PAR ORES. MINUTES OF MEETINGS. THE Nineteenth Annual Meeting of the Society was held on Wednesday, May 14, 1890, at 2 o’clock p.m., in the parlor of the Beebe House, Put-in-Bay, Ohio. Eugene G. Blackford, the President of the Association, promptly called the meeting to order, and, in the absence of the Recording Secretary, Fred. W. Brown, of Pennsyl- vania, Edward P. Doyle, of New York, was elected Secre- tary pro tem. Before proceeding with the regular business of the Asso- ciation, the President requested Mr. C. V. Osborne, of Ohio, to explain to the members the programme provided for their entertainment during the meeting. After Mr. Osborne’s explanation, the President, by unanimous consent, appointed C. V. Osborne and Dr. J. A. Henshall, of Ohio, a committee on local entertainment. Mr. Hasbrouck, of the Castalia Trout Club, extended an 4 invitation to the Association to visit the ponds of the Club and partake of a trout dinner. On motion of Dr. H. H. Cary, of Georgia, the thanks of the Society were given the members of the Castalia Trout Club for their kind invitation. The President read a letter from Mr. Frank Clark, of the United States Fish Commission, regretting his absence from the meeting. The President then addressed the meeting at length. PRESIDENT’S ADDRESS. Gentlemen of the American Fisheries Society : I congratulate you upon so large an attendance at so re- mote a place as Put-in-Bay, Ohio. For many of our mem- bers to come here involves a journey of some hardship and considerable expense; that we have here to-day gen- tlemen from Georgia, Pennsylvania, Michigan, Minne- sota, and Wisconsin is proof that interest in the Society and its work has by no means lessened. I hope that when we shall meet at some more central place, although none perhaps can equal this as to beauty of surroundings, a still larger number of our members may be present. All things considered, however, this promises to be one of the most successful of our meetings, and I have no doubt that the object of our Society will be grati- fyingly promoted. It may not be amiss at this point to say something about the original design of this Association, and to give some idea of the work it has accomplished. Eighteen years ago the Society was organized under the name of the American Fish Culturists Association by a few practical fish cul- turists, who hoped to make it an aid to the financial part of their business, and to secure, if possible, a better and more uniform price for the product of their skill. The aims and 5 scope of the Society’s work were enlarged from year to year, until we now have a Society embracing within its list of members the most distinguished tish culturists of the world. It has broadened out with its growth in membership un- til its original object has been forgotten, and the question of how to best advance purely scientific interests of fish culture and fish distribution and fish protection have be- come of paramount importance. It is unnecessary for me, perhaps, to remind you of how much we have accomplished in the past, for you have all shared in the labors and are acquainted with the facts. There can be no doubt but that the present United States Fish Commission, with its value and importance and its great success, owes its origin and development, in a great measure, to this Society. Papers read at our several an- nual meetings have done more than anything else to stim- ulate the growth of the interests in fish culture and fish protection throughout the United States, and I think we can say, without boasting, that the present advanced con- dition of this science in this country is due, in a large measure, to the work of the American Fisheries Society. As illustrative of the practical advance of fish culture and the great results now obtained by it, it may not be out of place for me to give you at this point a brief account of the work of the Commission of which Iam the President. This Commission has been remarkably successful, and the past year was one of the best in its history. Its work has been divided into three heads—first, fish propagation ; second, fish and game preservation; third, granting fran- chises for oyster cultivation and protecting natural-growth oyster-beds. The first and principal work of the Commission is, of course, the artificial propagation of fish. By the terms of the act creating the Commission, they are to examine the streams and lakes of the State, with a view to stocking . 6 them with fish. In this department the Commission is doing a great work. Last year they operated five hatch- eries, and the coming year two more will be added. This will give the Commission seven hatcheries, all capable of producing excellent results. These hatcheries are at Cale- donia, Cold Spring Harbor, Adirondack, Sacandaga, Fulton Chain, Clayton, and Chautauqua, and their importance is in the order I have given them. The total output last year of the five then in operation was 31,489,638 fry. Of this number there were 3,099,900 brook trout, 927,500 brown trout, 5,329,000 lake trout, 863,000 California trout, 1,350 quinnat salmon, 78,000 land- locked salmon, 687,188 salmon, 4,600,000 smelts, 30,000 shrimps, 4,100,000 tomcod, 1,900,000 white-fish, 6,053,200 shad, 3,780,000 frost-fish, and 2,625 adult fish of various kinds. This year’s distribution will be much larger than ever before, and an increase of at least 30 or 40 per cent. is looked for. The entire distribution for the past ten years was, in round numbers, 203,363,600 fry, of which the principal distribution was of lake trout, brook trout, and shad; 39,055,000 of lake trout were distributed, 18,140,000 brook trout, and 81,138,000 of shad. The correspondence of the Commission from various parts of the State shows conclusively that artificial propa- gation and stocking have been wonderfully successful. In spite of continuous fishing, consequent to the rapid in- crease of population, the Adirondack streams, stocked yearly by the Commission, are full of trout, the large lakes in the central part of the State afford excellent lake trout fishing, and shad and salmon are increasing in numbers in the Hudson every year. The Commissioners recently suc- ceeded in obtaining appropriations for the necessary fish- ways in the last-named river, and as soon as they can be built the work of the Commission in this stream will show a more abundant results. The last Legislature has made an appropriation of $3,500 for a fish-car for fish hatching and fish distribution, and this, it is also believed, will mate- rially aid our work in this department. The prospects for the future work of the Commission in fish propagation and in stocking streams are excellent, and great results will certainly be obtained. In the department of fish protection the Commission has been most successful. The Legislature of 1888 provided for the appointment of a corps of fish and game protectors forthe State, and created an executive head, to be known as the Chief Game and Fish Protector, all of whom are appointed by and subject to the Fish Commission. This is what the State most needed, and the enforcement of the fish and game laws has been much more thorough and satisfactory. During the year ending September 30, 1889, 180 suits for penalties were successfully prosecuted, the receipts from fines amounting to $4,104 51. The work this year has been even more successful, and the results have been most gratifying. At the last session of the Legislature the Commission succeeded in having passed an act for a commission to revise and codify the game-laws of the State. This commission will consist of one member from the Fish Commission, one from the Society for the Preservation of Game, and one Deputy Attorney-General of the State. The work of this Commis- sion will be most important, and the presentation by them to the Legislature and the subsequent adoption of a con- cise and consistent code of game-laws will do a great deal towards securing the successful and vigorous protection of game and fish. In the department of oyster culture great progress has been made, although the first surveys are not yet finished ; 261 franchises have been issued and $4,520 in fees have been paid into the State Treasury. 8 A large number of applications for oyster territory are now ready for favorable consideration, and the receipts by the State this year will be correspondingly large. In addition, the benefit derived by this important in- dustry from this law cannot be overestimated, and is thoroughly appreciated by the oystermen. We think that the Commission, in its various departments, can claim, without boasting, that valuable results have been obtained for the State, and that no investment made by it shows more gratifying returns. You will pardon me for the time I have taken in speak- ing of my own State, but the work done by the Commis- sion there is simply indicative of the progress of fish culture, and shows the great value of the work this Society may do and has done in stimulating the interests of the country in the artificial propagation of fish. Many other States have vigorous and successful commis- sions, perhaps, of greater efficiency than that in which I am possibly more particularly interested, and that all the State Commissions have been helped by our Society is beyond question. These meetings cannot fail to produce excellent results. Aside from the pleasures of social re- union and intercourse, the mutual expression of practical experiences in fish work is of great value to all of us. I thank you for the attention you have given me, and congratulate you upon the present standing and member- ship of the Society, and await your further pleasure. The Treasurer, Henry C. Ford, presented the financial report of the Society for the year ending May 14, 1890, which report was received, and, on motion, accepted. 9 TREASURER’S REPORT.

The President appointed W. L. May, of Nebraska, J. Vernon Long, of Pennsylvania, and Fred Mather, of New York, as such committee. Dr. R. O. Sweeny, of Minnesota, moved that the accounts of the Treasurer be audited and allowed. The motion was unanimously adopted. Hershel Whittaker, of Michigan, moved that a recess of ten minutes be taken to enable the Committee on Enter- tainment to prepare a list of papers to be read before the Association. On re-assembling, Dr. Henshall, from the Committee on Entertainment, reported as follows : That papers by the gentlemen whose names are given below would be read: Fred Mather, Hoyt Post, Dr. R. O. Sweeny, Hershel Whittaker, Emory D. Potter, Dr. J. A. Henshall, John M. Bissell, John Gay, and William P. Seal. On motion of Hershel Whittaker, of Michigan, the President was authorized to appoint a committee of three to draft resolutions expressing the sentiments of the Society as to the bill of Senator Paddock relating to the United States Fish Commission now before the Congress of the United States. The President appointed Hershel Whit- taker, of Michigan, C. V. Osborne, of Ohio, and W. L. Powell, of Pennsylvania, as such committee. The following persons were proposed for membership in the Society, and by unanimous consent were duly elected : Charles F. Imbry and George T. Moon, of New York (pro- posed by E. G. Blackford); Hon. Seymour Brown, of Deerfield, Mich. (proposed by Hershel Whittaker) ; William P. Seal, Washington, D. C., and A. H. Miller, 1020 Spring Garden Street, Philadelphia (proposed by Henry ©. Ford); Hon. J. J. Stranahan, Chagrin Falls; 11 Ohio (proposed by J. A. Henshall), and Hon. Emory D. Potter, Sandusky, Ohio (proposed by Fred Mather). On motion of Dr. R. O. Sweeny, Washington, D. C., was chosen as the place for holding the next meeting of the Association. On motion of Hershel Whittaker, of Michigan, the question as to the time for holding the next meeting was made a special order for the evening session. On motion of C. V. Osborne, of Ohio, the Secretary was directed to write the members of the Fishing Club at Middle Bass Island to attend the evening session of the Society. Dr. Sweeny, of Minnesota, moved that Mr. Hasbrouck, of the Castalia Trout Club, be invited to sit with the Society during its-sessions. The motion was unanimously adopted. The President read letters, regretting their inability to be present at the meeting, from Col. Marshall McDonald, W. T. Dennis, N. D. Tomlin, Charles G. Atkins, and W. P. Seal. The reading of papers then began and continued for some time. These papers will be found in full in Part Second of the proceedings. Dr. R. O. Sweeny moved that the question as to the advisability of printing an edition of the reports of the Society from its organization be referred to the Executive Committee. The motion was unanimously adopted. Henry C. Ford, President of the Fish Commission of Pennsylvania, addressed the meeting on the work of the Pennsylvania Fish Commission, and gave testimony as to the value of fish-ways. He said that large numbers of shad have been seen ascending the fish-ways at Lackawaxen. On motion, Dr. R. O. Sweeny was permitted to read two papers by title, which papers the Secretary was directed to print in the annual report. 12 A number of interesting papers were read, after which, on motion, a recess was taken until 8 P.M. Minutes of an adjourned meeting of the American Fish- eries Society, held Wednesday, May 14,at 8 p.m., in the parlor of the Beebe House, Put-in-Bay, Ohio. Reading of the minutes of the afternoon session was on motion dispensed with. Henry C. Ford, of Pennsylvania, proposed for member- ship C. T. Hasbrouck, of Cleveland, Ohio; Dr. J. A. Hen- shall, of Ohio, proposed Mr. J. E. Gunkell, of Toledo, Ohio. By unanimous consent the by-laws were set aside, and the gentlemen elected to membership by acclamation. Hershel Whittaker, of Michigan, from the committee appointed for the purpose, reported the following pream- ble and resolution, which, upon motion, were unanimously adopted : Whereas there is now pending before Congress a prop- osition to change the organization of the United States Fish Commission, attach it and make its chief and employes of every grade and position subject to the appointment and removal by the Secretary of Agriculture, which legisla- tion we feel to be directly inimical and prejudicial to the progress and proper consummation of the original intent and present practical and efficient work of the Commission ; Resolved, That the American Fisheries Society, which for the past twenty years has been actively interested both in the science and practical development of fish culture, does most earnestly and emphatically protest against such legislation, and therefore would respectfully urge our Senators and Representatives, by every proper means, to oppose and defeat such obnoxious enactment, On motion, the Secretary was instructed to have these resolutions printed and sent to every Senator and Repre- sentative in Congress. Mr, Mather, from the committee appointed to make nom- 13 inations for officers for the Society for the ensuing year, presented the following report: To the American Fisheries Society : Your Committee on Nominations for officers would re- spectfully report the following : President, EUGENE G. BLACKFORD....New York City. Vice-President, Dk. JAMES A. HENSHALL, Cincinnati, O. Treasurer, HENRY C. FORD........... Philadelphia, Pa. Recording Secretary, EDWARD P. DOYLE, New York City. Cor.

Upon motion, the Secretary was then directed to cast one ballot for the officers recommended by the Committee on Nominations, which was done, and the President declared the officers named duly elected. The special order for the evening session then came up, and it was moved and seconded that the next annual meet- ing of the Society be held at Washington, D. C., the second Wednesday in February, 1891. The motion was put and carried. 14 At this point Mr. Osborne, from the Committee on Enter- tainment, explained the character of the excursions to be made on the following day, and gave the necessary infor- mation to the members as to the time of leaving. A paper was then read by Hon. E. D. Potter, of Ohio (see Part Second), on Origin of Artificial Propagation of Fishes in the United States. On motion of Dr. Cary, thanks of the Society were voted Mr. Potter at the conclusion of his paper. Mr. Broman, of Put-in-Bay, one of the oldest fishermen of that place, gave the Society some interesting information as to the habits of white-fish. A paper was read by Dr. J. A. Henshall, as to fish pro- tection. (See Part Second.) A paper by John A. Bissell, of Michigan, entitled ‘‘ The Grayling,’ and one by the same gentleman entitled ‘* Mich- igan White-fish Hatchery,’’ were ordered printed. (See Part Second.) Mr. Ford, of Pennsylvania, read a paper prepared by John Gay and William P. Seal, of the U. 8S. White-fish Commission, entitled ‘‘ Past and Present Aspect of Fish- culture,’ with an inquiry of what may be done further to promote and develop the science. (See Part Second.) Mr. Fred Mather moved to reconsider the vote by whi the date of the next annual meeting was fixed. The motion was carried. The question then recurred on the original motion. Mr. Whittaker moved to amend so that the meeting should be held the last Wednesday in May. The amendment was adopted. The original motion was then carried. W. L. May, of Nebraska, offered the f ollowing reso lution, which, upon motion, was adopted : Resolved, That this Society urge upon the different State Fish Commissioners the necessity of sending to future annual meetings the Superintendents of their respective 15 State Hatcheries at the expense of proper funds under their control. On motion the meeting then adjourned. EDWARD P. DOYLE, Recording Secretary. Pei” aC WIN, EGGS OF PIKE-PERCH—S. Vitreum. By Frep MATHER. On April 25 of the current year I had some eggs of this fish in hand. They were not in good order on receipt, but there were hopes of some. On looking up the literature of the hatching of pike-perch, but little was to be found beyond statistics, and that little was in the reports of this Society, in an article by Mr. James Nevin. On measuring the eggs, my estimate of the number in 2 quart greatly exceeds that of Mr. Nevin, who gives it as 100,000. From my notes, taken at the time of receiving the eggs (in water), I find the following: the eggs measure thirteen to the linear inch, 169 to the square inch, and 2,197 to the eubic inch. As there are 57,775 cubic inches in a quart, there would seem to be 126,931 eggs in it; but the above calculation is made on the supposition that the eggs would be piled up in such a way that their diameters are in line, thereby wasting the greatest space in the interstices. As this is not the zase, I have, after careful counting and esti- mating, added 350 eggs to each thousand for this filling of chinks, land in this case the addition would be 44,450, making the total number of pike-perch eggs in a quart to be, in round numbers, 171,000, which I believe to be nearly 16 correct if the eggs measure thirteen to the linear inch, as mine did. In the last report of the New York Fishery Commission I gave an estimate of the number of eggs in a common sun- fish, but did not add for the filling of interstices. After- wards I gave the facts to a newspaper man at more length, and he printed the following: ‘‘Last summer Mr. Fred Mather, Superintendent of the New York Fishery Commission, computed the eggs in one of our common pond sun-fishes. The extreme length of the fish, including the caudal fin, was 64 inches, and its weight was 54 ounces. The fish was captured on June 16, and was nearly ready to spawn; the weight of the ovaries was 1} ounces. The eggs measured twenty-eight to the inch, making 21,962 to the cubic inch. The displacement of the ovaries in water was a trifle over two cubic inches, and the number was estimated, in round numbers, to be 44,000—a most enormous number forso small a fish. This fish makes a nest in the sand or gravel near the edge of ponds or on shallow spots, and, according to Mr. Mather, it is the male fish which guards off intruders after the eggs are laid—a fact not known to ichthyologists, who study fishes after they have been kept in alcohol.” Adding 350 eggs to each thousand, for closest packing, and the total in this smali fish would reach 58,000, a figure that I believe to be a more correct one. CoLp Spring Hargor, N. Y., April 30, 1890. THE. DETROIT WHITE-BISH SEA LION. By J. H. Bissett, or MICHIGAN. Among the notable fish-cultural establishments of the United States, there is one of which very little has been said in the public press outside of the State. It is the White-fish Hatching-house of the Michigan Fish Com- mission, located at Detroit. 17 The commercial value of the white-fish very early attracted attention to its artificial culture, after it began to be in- quired about and discussed whether any fishes could be advantageously cultivated by artificial methods. Even in the early sixties attempts were made at it—of course, crude and, in the main, unsuccessful—but still they were steps ahead and in the right direction. It was not, however, until a Fishery Commission had been reluctantly granted by the Legislature in 1873 that efforts were made in the systematic way necessary to insure success. After two years of hatching by contract with a private individual, Orren M. Chase came from Cale- donia, N. Y., and erected a humble building near the river front, in Detroit, on a rented lot. The house was about 20x50 feet, one story, and battoned. It was equipped with Holton boxes, which, in their day, were the best known apparatus for that work. A few years of observation on the working of the Holton box showed to the clear mind of Orren Chase a better way, one which has held its place for twelve years, and has not been improved upon yet—that is, the glass jar. There is not space here to go into the history of the evolution of Mr. Chase’s idea ; it was, like most inven- tions, a series of experiments which, step by step, led the seeker after truth, who steadfastly follows true principles, to a correct conclusion. The glass jar furnished the eggs a regulated flow of water upward, which gives constant motion, keeping the eggs clean and preventing the dead or imperfectly fecun- dated ones from injuring the sound ones. Besides enabling the handling of a very much greater number of eggs with a given water supply and a given room space, by using the Same water over and over; it allows two persons to take better care of 40,000,000 eggs than eight or ten persons could of 10,000,000. This house contained 212 jars, with a capacity each of about 140,000, making the aggregate of the house, if all were filled, of nearly 30,000,000. In 1883 the Legislature 18 furnished the means for erecting and equipping the present house. It is located at the corner of Champlain Street and Campau Avenue, in a nice residence neighborhood, and has often been mistaken for a plain church. Its dimen- sions are 40x 80 feet, with a wing 38x55 feet. The main building is a single room full length and width, excepting a small office and bedroom partitioned off from one corner. The floor is of solid concrete. The water supply is from the city water-supply pipes in the adjoining streets, the connections being equal to five one-inch pipes. The equipment was 312 glass jars of larger size than used in the old house, as they showed, by actual measurement and count for three seasons, an average of 156,000 to the jar, making a total for the house of 48,672,000 white-fish eggs. This house was very carefully constructed with a view to maintaining an equable temperature. Outside of the stud- ding it is sheathed with common boards, over which very heavy building-paper is placed, and the clapboards outside of that. The space above the ceiling being quite large, is opened at both ends and covered with sloping boards; three aper- tures were left from this space connecting with the main room of the house, which are controlled by hatches. The windows are all rather high, and on the inside are supplied with wooden slat-shades, which allow of regu- lating the light as desired. It is generally understood that no more light should be admitted than is necessary for the proper handling of the eggs. Over the wing are large storage-rooms for the cans and other apparatus necessary about such an establishment. The jars stand on frames about twelve feet high, placed the long way of the house, each frame carrying on its out- sides rows of the jars one above the other. Within the frame are alternate feed-troughs for water supply to the jars and the wasteways into which the water flows from the 19 lips of the jars, there being a feed-trough and waste for each row of jars. The jar-frames were about twenty-three feet apart at one end, and they were connected by cross-tanks or troughs, by which the waste water from one side was carried across the house to the feed-trough on the other frame. The large cross-tank on the floor into which the water finally flowed, and in which the young fish were gathered in hatching-time, was connected with a long tank extending between the jar-frames, 48 feet in length, 4 feet wide, and 23 feet deep. In 1888 a hatching-house on the Little Traverse Bay was given up, and its complement of jars were accommodated in the Detroit house, making its number of jars 520 and the house capacity over seventy millions. In 1889 the house was remodelled within by the erection of two addi- tional frames, taking out the central tanks, and making each frame carry four tiers of jars on each side. The number of jars was increased to 1,125, giving the house now a capacity of carrying 150,000,000 white-fish ova. By the new arrangement the storage-tanks for the young fish, four in number, are placed in the wing, or tank-house, the storage-tanks there being connected by siphons to the. collecting-tanks in the main or jar-house, for transferring the young fish. This house is supplied with a steam-boiler and pump. The boiler answers the double purpose of heating in ex- tremely cold weather, and furnishes power for the pump in case of accident to the water supply occasioning a stop- page of water from the city mains; the pump will lift the water from the tanks on the floor to the upper trough, and use the same water over and over as long as needed. The house is furnished with a stove, and that most necessary ad- junct for ventilation—an open fire. Every hatching-house ought to be provided with a good, large, open fireplace to keep it dry by proper ventilation. There is no provision that can be made for the comfort of the men equal to that. 20 The present season there are about 900 jars filled in this house, the take of eggs in Detroit River in November last not being sufficient to fill the jars. However, with the average hatch, the house will turn out about 121,566,000 white-fish fry, to be planted in April and May, 1890, in Michigan waters. The Detroit hatching-house, as constructed and equipped in 1883, cost about $6,500; its subsequent improvement and alteration, with increased apparatus, about $4,000 more. How such an establishment is stocked with eggs, as it requires nearly one hundred solid bushels, and how its millions of product are planted, it will take another article to tell. ON THE DESIRABILITY OF THE ESTABLISHMENT, OF GREAT PUBLIC AQUARIA IN THE UNITED 'SDATES: By WituiaAM P. SEAL. The beginning of the development of great public aquaria in the United States will undoubtedly be hailed by anglers, fish-culturists, biologists, and as well by the general public, as a ‘‘consummation devoutly to be wished.’’ Some past experiences in this direction offer but little encouragement if not positive discouragement, in this direction. But, as in all advances in human knowledge, there is an experi- mental stage of development by which, through repeated failure, there comes finally a general knowledge of the conditions required for success. In the case of fishes, living in another element, the difficulties in providing them with suitable conditions are apparently greater than with land animals. There is the necessity of providing for fishes in an artificial condition an abundance of oxygen, or air, the amount of which, in suspension in water, from various causes, is exceedingly variable, therefore requiring an artificial system of aeration. 21 There is, no doubt, a more rapid accumulation of car- bonic acid gas and other deleterious gases in the water. There is the difficulty of providing suitable food. There is also the delicate nature of fishes to contend against ; the fun- gus growths which infect them wherever scratched or bruised, or in weak or diseased condition, and the numbers of parasites infesting them, some of which are very destructive. And yet, upon a fair examination, it may be said that, in the present state of our knowledge, the handling of fish, or the keeping of them in captivity, is probably attended with but little, if any, greater mortality than is usual in the keep- ing of any but domestic animals. And even among do- mestic animals the ravages of epidemics are frequent, and the unaccountable deaths occur at times in quite as great a proportion as ever occur among wild animals in captivity. The fact that some species of animals are more amenable to the conditions of captivity than others, and that the same is true of the individuals of a species, is, of course, generally understood; but it is not usually recognized in such a way as to make the knowledge of practical value by providing for each the conditions necessary for their comfort and happiness. We recognize this necessity in providing for our pet animals or our stock, because this is a matter that comes home to the individual; but in our aggregations of animals for purposes of exhibition or obser- vation, through a false economy generally, or, perhaps, often through ignorance of the real necessities (for such work is often taken up by inexperienced persons), we provide what may be called comfortable prisons for the confinement of animals whose natures chafe at all restraint, and whose natural instincts are thus wholly checked and thwarted; the sexual instinct, that of migration, hiber- nation, the variation of food and temperature, and, in the case of certain fishes, perhaps, a necessity for a change of character of water—fresh, salt, or brackish, as required— and the activity possible in greater space, ete. 22 When we consider that we may confine the smaller species of fishes, such as the gold-fish, minnows, shiners, sticklebacks, darters, and others, in ordinary aquaria, which, owing to the small size of the fish, give them considerable room, and have them to live contentedly, spawn naturally, and live in every respect, apparently as happily as in their native waters, it becomes ap- parent that when we provide conditions proportionately adequate, we may expect the same results with any of our fishes. The desirability of the accomplishment of such results needs no argument to the mind of the fish culturist. It is, in fact, the only way in which we may obtain a knowledge of the habits of many of our fishes, hidden as they are from our view in the depths of the waters. To the biologist the opportunities afforded for investigation by such means are very great and of increasing necessity. To the general public, as a means of recreation and educa- tion in a branch of knowledge in which the ignorance is very great, but in which the popular interest is equally great, the value of great public aquaria would be well worthy a general popular support. It is quite apparent that in most of the attempts hereto- fore made to establish aquaria in the United States, the con- ditions established were such as from our present knowl- edge we can say were inimical to any permanent success. Of course, it should be understood that we are at present but on the threshold of our knowledge in this direction ; but we may claim that there are certain great principles underlying success in the keeping of living things in healthy and happy condition, and that a violation of these plain requirements invites certain failure. From a standpoint of practical experience established by years of observation, in accordance with these principles, and in view of minor results actually achieved, we may now confidently proceed to the successful establishment of great aquaria. 23 A brief explanation of these fundamental principles may be necessary for a proper understanding of the subject from the writer’s standpoint. It is well known that many ani- mals, when held in restraint, exhibit all the symptoms of fear, grief, rage, etc., and frequently refuse all food, and pine and die. Many birds will beat themselves to death on the wires of their cages. All such restraint, evidently involving great suffering, is necessarily cruel and objectionable from that standpointalone. From a financial standpoint it is altogether objectionable, because the great mortality resulting from keeping animals in an unhealthy or unhappy condition makes the expense of maintenance of great collections of animals of any kind too great for financial return for private enterprise, or for popular sup- port for educational purposes, The attempts heretofore made in this direction in the United States, as well as the known financial aspects of the establishment of aquaria abroad, and of zoological gardens as well abroad and at home, justify the statements herein made. There is nothing to be gained by ignoring them. Whatever advance is made in the future must come from a recognition of the general principles herein sought to be explained. The establishment of the National Zoological Garden at Washington, under the direct management of a naturalist who has studied animals in their natural homes and haunts, instead of in books, promises to make a departure in such work in many re- spects, in a closer approximation of natural conditions, as far, at least, as the limited extent of space provided will allow. A much greater park, such as the entire Rock Creek Valley would make, affording all the room and vari- ability of surroundings necessary to the contentment of animals of widely divergent natures, would only be worthy of so great a country. In the establishment of great aquaria, when the subject assumes an importance deserving consideration, it will be 24 found that to follow in the methods of the past will, as heretofore, be to invite failure. The question of, in a measure at least, imitating natural conditions underlies all success. There can be no further question of its necessity, whether with aquatic or terrestrial animals. In regard to the mere question of space, it has been found with fishes that those which it is impossible to keep in an aquarium of a certain size, will live comfortably in one considerably larger. This has been tested in the cases of a number of species very difficult to keep, and it may be emphatically stated as a principle that as the area or space allotted to animals in captivity increases, the symptoms of depression will decrease and the difficulties in keeping them diminish in a like ratio. In the question of fishes, the question of the purity of the aquarium is one of the greatest importance. The oxida- tion of metals, the decomposition of paints, and the gal- vanic action resulting from the use of more than one metal in salt water, are all inimical to success. The further inju- rious effects of the decomposition of organic matter, the food or excreta of fishes, etc., in combination with the first-mentioned elements of injury, still further increase the difficulty. Thus the necessity for purity or freedom from injurious chemical action in tanks or circulatory apparatus is one of the principles upon which success depends. It has been satisfactorily demonstrated that an abundance of light, and at least some sunlight, is necessary for the healthy development of aquatic plants. This is probably true of almost all living things. The healthy development of plant-life in its turn has its beneficial effect on the de- velopment of animal life, aside from the direct benefits conferred by the action of sunlight in liberating oxygen. Even where animals live in a state of semi-darkness, con- cealed among stones or plants, the air or the water pene- trating to their homes is revivitied by the potent influence 25 of sunlight. The establishment of an aquarium therefore demands, as one of the conditions of success, an abundance of light, the same conditions, in fact, necessary to life in the pond. The closer we approach this ideal, the greater the success will be. The establishment of a marine aquarium at Washington by the United States Fish Commission has furnished the means of making many interesting observations, and has practically demonstrated that it is possible to maintain marine aquaria away from the sea without very great diifi- culty and without greater mortality, probably, than is usnal where the water may be pumped directly from the sea. The chief difficulties are in the transportation of fishes from the sea without injury, some of them being of very delicate nature. This is more easily accomplished at a time when the temperature is moderate, being neither at one extreme nor the other. The control of temperature in the aquarium, owing to our extremes of heat and cold, is a matter of some difficulty, but must be overcome as an element of success. The more nearly we can approach an equalization of temperature, the more satisfactory will be the results, no doubt. The Washington Marine Aquarium is built ina green- house-like annex to the central station of the United States Fish Commission. This style of structure affords the necessary light. Twenty-four aquaria, of from sixty to seventy tive-gallons capacity each, are arranged to form a gallery in a cavern or grotto built in imitation of rock, which is lighted wholly by the daylight passing through the water from above; 6,000) gallons of water are used. This is pumped from a brick reservoir outside to a tank at an elevation of about forty feet, from which it descends under the resulting pressure—about twenty pounds—into the aquaria through very small glass nozzles, thus effect- inga most efficient aeration. The materials of construction of aquaria, reservoir tanks, circulatory apparatus, ete.— ‘ 26 everything with which the water comes in contact—are hard and soft rubber, wood, slate, glass, and brick, nothing whatever of an injurious character. Most of the loss of salt water is supplied by water made sufficiently salt by the use of sea salt. Asa result of the abundance of light afforded, the slate backs and sides of the aquarinm, and the bare stones placed in them, are being gradually covered with a dense growth of alge developed directly from the spores of alge brought from the sea, just as it is seen de- veloping on sea-walls and rocks, something, perhaps, alto- gether unknown under the usual unfavorable conditions. The observations of the habits of fishes afforded by these aquaria have been of great popular interest, while the advantages of the observations to the general work of fish culture in opening up new avenues for experiment in prac- tical work may prove to be considerable. Some recent statements concerning the breeding habits of the common sunfish elicited the fact that the knowledge of the subject is not positive. Referring to this, Prof. Theodore N. Gill was led to say to the writer that ‘‘ it is a Shame that we know so little of the habits of our com- monest fishes.’”? To which might be pertinently added, it is ashame that the facilities afforded for observation of fishes are so limited. It is to be hoped that a great aquarium may be developed in connection with the work of the United States Fish Commission, inasmuch as in addition to its practical use- fulness to that organization, and its great popular interest, the experience there afforded will be of general public benefit in affording a sure basis of practical knowledge upon which the great cities of the country or institutions of learning may draw when they decide to take up such work. 27 GRAYLING IN MICHIGAN. BY JOHN H. BISSELL, OF MICHIGAN. Having been asked some questions about this rare member of the salmon family, I assume that the subject may be of interest to your readers who are anglers. Where is the Michigan grayling found to-day? Any one really wishing to know may take a map of Michi- gan to follow my answer. Begin at a point on Sag- inaw Bay at the mouth of Saginaw River, and draw a line west by southwest to the mouth of the Muskegon River, on Lake Michigan, and all of the grayling waters are to the north and west of your line. Let us start again at the same point on Saginaw Bay and fo low the coast northward towards the Straits. The first stream of any size is the Rifle River. I am informed upon good authority that grayling have been found within the past three or four years in the Rifle and its tributaries. I am not sure that the appearance of the fish there is of so recent a date as my informant believed, but with a fairly extended knowledge of such matters I had never before heard of their being there. There is no reason why they might not live and flourish in the Rifle, as its waters are suitable. The next river to the north is the Au Sable, where gray- ling have been known since 1841. This is one of the most famous of fishing-grounds. While to those who fifteen years ago used to kill from one to two hundred grayling a day, this river seems to be ‘‘ fished out ;’’ it still furnishes fair sport to the humble philosopher who is satisfied with a moderate reward for his day’s work. To the north, in Presque Isle, Montmorency, and Alpena counties, is the Thunder Bay River, with its numerous branches of fine water. I have never heard of grayling in any of them, but from their situation and the character of the waters, Ishould want good proof that grayling were not to be found in the head-waters of this system. This is des- 28 tined to be a great brook-trout region, as the railway facil- ities now permit its being stocked. The Pigeon and Sturgeon rivers, flowing nearly north into the Straits of Mackinac, at Sheboygan, are well stocked with grayling. From the Straits around to the head of Grand Traverse Bay are the rivers and brooks which contained brook-trout before any were planted by the State. Originally there were grayling in all these streams, but for twenty years or more these fish have been so scarce here that they have really ceased to be grayling streams. South of the Board- man River, which flows into Grand Traverse Bay to our imaginary line, is a distinctively ‘‘ grayling country.”’ The main rivers are the Manistee and the Muskegon, the whole region spoken of being drained by their tributaries, except two much shorter streams, the Pere Marquette and W hite rivers. This comprises the grayling region of Michigan. There is one stream on the Upper Peninsula, about twenty miles from Houghton, where grayling are found—the east or north branch of the Ontonogon River, crossed by the DeS25; we. Rai. The rivers and their branches above mentioned are most conveniently reached from the interior of the State by the Michigan Central Railway (Mackinaw Division) for the eastern and northern, and by the Grand Rapids, Indiana, & Chicago and West Michigan for the western streams. Over a large part of the territory described the grayling has beyond question become very scarce, mainly by reason of the indiscriminate fishing of the citizens, lumbermen, and hunters, as well as fishermen from other States. The lumbermen and hunter have speared and netted and used dynamite for meat during the close season. The others have killed more than they could use. The running of logs has undoubtedly done great injury to the grayling by the disturbance of their spawning beds, as they use the 29 channel of the main stream, not seeking the brooklets and shoals, as the trout usually do. Still there are grayling yet to be had, and most delightful sport it is to capture them with delicate tackle. Nothing has been done by the State for preserving the grayling beyond experiments to determine to what extent the grayling can be bred in captivity like the brook-trout. The experiments have not been successful. Grayling kept in stock-ponds have gone for several seasons without show- ing any signs of spawning. The experiment is now being prosecuted in a large wild-pond—that is, a portion of a natural grayling stream screened off, where the fish re- main in entirely natural conditions of bottom and shade without any molestation. Unless the approaching spawn- ing season turns out better than 1888 and 1889, I think the State Fishery Commission will conclude that the only feasible way to increase the grayling will be to establish one or more camps on the Manistee, or other stream where spawners can be secured, and handle the fish there, taking the eggs from fish caught in spawning season, as is done with white-fish and shad, and hatching in shad-boxes or some similar appliance, in the river, turning loose the fry intended for the stream where operations are conducted and transporting to other localities in carrying-cans. There is no doubt that if nothing is done to save them they will become practically extinct in the next five or ten years. There are some inaccessible places where they will un- doubtedly linger many years; but they are or will become practically extinct when they are so few and so scattered that their pursuit no longer furnishes reasonable sport to a reasonable and modest angler. The grayling waters of Michigan are cold, clear, rapid streams, flowing through bottom-lands and sand regions, and in no case, to my knowledge, over rock formations, an alternation of the most beautiful ripples and pools. 30 EXPERIMENTS IN THE IMPREGNATION OF PIKE- PERCH EGGS. By HersCHEL WHITAKER, OF MICHIGAN. The eggs of the wall-eyed pike, after having been for some time in water, measure about two millimeters (about 1-12th of an inch) indiameter. The egg has an‘enveloping membrane (or zona radiata) of the usual form. Outside this is a second thinner membrane, which wrinkles and stains more deeply in the hematoxylin than does the inner zona radiata. The eggs are very adhesive, and it is to this outer membrane that the adhesiveness is due. ‘There is probably also a third membrane within the zone, but this has not been determined with certainty. Within these membranes is the yolk, having a diameter of 1.4 mm. (about 1-18th of an inch). The yolk is spherical, and in one side of it is imbedded a spherical oil-drop having a diameter of .8 mm. (about 1-31st of an inch). The oil- drop causes the surface of the yolk-sphere to protrude to one side. The oil-drop being lighter than the yolk, is always turned upward, so that in looking at the egg from above the oil-drop appears to be in the middle of the yolk, while in looking at the egg from the side the oil-drop appears to be at the top of the yolk. I shall speak of that pole of the yolk in which the oil- drop is imbedded as the upper pole, and of the opposite side as the lower pole. A line drawn about the yolk, half way between these two poles, will be spoken of as the equator. When the egg is at rest the lower pole of the yolk rests upon the egg membranes, so that the space which separates the yolk from the zona is altogether above and at the side of the yolk and oil-drop. This space may be spoken of as the breathing space. Surrounding the yolk and oil-drop is a layer of protoplasm, which forms an investment for them and separates them from the water in the breathing space. 31 This layer of protoplasm is extremely thin over the greater part of the yolk, and is tightly stretched over the protuberance formed by the oil-globule. It is not, how- ever, uniformly thin, but in one place has a disk-shaped thickening. This thick disk of protoplasm (germinal disk) is concave towards the yolk and convex on its opposite side, and is fitted like a saucer against one side of the yolk. Its position is such that its center is upon the equator of the yolk, so that in looking at the egg from above one sees the edge of the germinal disk. Outside the disk the layer of enveloping protoplasm is so thin that it cannot be easily seen except by the use of reagents. So long as the yolk is within this enveloping layer of proto- plasm it is entirely transparent and colorless. If the en- veloping layer be ruptured so that the yolk passes out and comes into contact with the water, it becomes instantly opaque and of a milk-white color. The foregoing description applies to the egg after it has been some time in the water. As the egg leaves the female the egg membranes are not separated from the yolk by a water-filled space, but are everywhere in close contact with the layer of protoplasm which invests the yolk. When the egg is placed in water, the water passes rapidly through the egg membranes and accumulates between them and the yolk. In this way the membrane becomes gradually separated from the yolk by a water-filled space —‘‘ the breathing space.”’ By this passage of water through the membranes they become tightly stretched and tense, so that an egg which at first feels under the finger like a piece of soft putty, becomes hard to the touch by the absorption of water, and feels like a shot. This ‘‘filling’’ of the egg takes about two hours. The foregoing account of the structure of the egg is sufficient to an understanding of the mechanical arrange- ments that it presents. 32 As it seemed likely that forsome reason a large per cent. of the eggs failed to be impregnated, my attention was first directed to determining the first differences between impregnated and unimpregnated eggs. In order to determine the question with certainty for this particular animal, the following experiment was tried (quoted from note-book) : APRIL 16, 8:45 A.M. After washing the surface of the body of a female fish in the region of the external opening with weak acetic acid, in order to destroy any spermatozoa, the eggs were stripped into dishes containing water. Into one dish milt was immediately stripped ; the other was left without milt. These were marked lot 1 and lot 2 respectively. Lot 1. Examined at 1:45 p.m. (the eggs having been kept in a cold room), and found segmentation going on. The germinal disk is divided into either two or four cells. Lot 2. Examined 8 a.m., April 17th, twenty-four hours after impregnating lot 1. The eggs were firmly set in a mass on the bottom of the dish. One hundred taken at random were examined with following results: Showing normal germinal disk without trace OF SCOMENtAMON 6 chee. mye ee 82— 824 Showing abnormal germinal disk with aac laile traces of first or second segmentation. .... 4— 4% Injured by rupture of protoplasmic invest- ment of yolk, so that yolk had escaped and egg had ‘turned white’... -.. 6s: +. 14— 144% Dota se: SRR ES LD ese 100 100% This experiment was pceigaieds repeated without, how- ever, counting the eggs, and always with the same result. Segmentation of the germinal disk is, therefore, the first easily recognized sign of impregnation. In order to determine the percentage of unimpregnated eggs among those taken by the men and ready for ship- 33 ment to the Detroit hatchery, the following counts were made : April 17th, 1 p.m., 252 eggs taken at random from a tub, after stirring the eggs in the tub, were examined with the following results : Segmented normally (i.e., impregnated)......... 141— 56% Unsegmented, normally (not impregnated)...... 26— 11% Injured by escape of yolk (white eggs)....... 85— 33% Potala dias. Shae hes cats - . ...-202=1004 The eggs marked as unimpregnated were set aside, and were found to be still unsegmented after twenty-four hours. This was several times repeated on other lots of eggs, with similar results. It shows that about 33% of the eggs are injured mechan- ically by the rupture of the protoplasmic investment of the yolk, while only about 11% perish from lack of impregna- tion. Even superficial examination shows that in nearly every case this rupture of the yolk takes place over the oil-globule. A consideration of the mechanical arrange- ment of the parts of the eggs shows that this is its weak spot. In the natural position the yolk sphere lies with its lower half against the egg membranes. These membranes, therefore, support this half of the yolk, surrounding it as if it were resting at the bottom of a cup. The upper half of the yolk is, on the contrary, not of the same form as the investing membranes; its spherical surface is interrupted by the protruding oil-globule. The result of this arrangement is that when any pressure is brought to bear on the egg membranes, so that the space within which the yolk lies is reduced, the yolk is able to resist this pressure by fitting itself against the egg mem- brane at every part of its surface except over the oil- 34 globule. The strain, therefore, comes on that part of the protoplasmic investment of the yolk which covers the oil- globule, and here it bursts. In almost every case the white spot which indicates the rupture of the yolk investment makes its appearance at the oil-globule, usually at its equator. Owing to the fact that the eggs are adhesive, it is the practice of the men in taking them to stir the eggs with the hand. By this means they detach the eggs that have adhered to the sides of the pail, and separate from one another those that have adhered together in bunches. This stirring takes place shortly after the eggs are placed in the pail and before they have filled with water. In this condition the space between the membranes and yolk is either absent or it is so small that it forms rather an aid than a hinderance to the bursting of the yolk investment. It is therefore desirable to find some means of handling the eggs so they will not adhere to the vessel in which they are placed, and so they will not adhere to one another to such an extent as to render it necessary to separate them by the hand. As to the first point, the men handling the eggs have found that they do not adhere to an ordinary unpainted wooden pail which by use has become rough inside, while they do adhere to the galvanized iron pails now in use. I have observed that while the eggs adhere strongly to glass, they adhere but slightly to cloth. I have no doubt that by the substitution of wooden pails for metal this difficulty will be overcome. It is likely that a metal surface might be oiled or other- wise so prepared as to prevent the adhering of the eggs. With regard to the second point, it has been found that if water be added to the eggs very slowly, while at the same time they are kept in motion by rocking the con- taining vessel, they do not then adhere to one another. This is true whether or not milt be mixed with the water. 35 Two lots of eggs were taken from the female and placed in two similar glass dishes, and to one milt was added. Water was then gradually added to each lot with con- tinual agitation of the eggs by rocking the dishes. This was continued until the dishes had been tilled with water and until the eggs had ‘‘filled.’’ In neither dish did the eggs adhere to one another or to the dishes. Eggs taken from either dish and transferred to another dish containing a larger quantity of water adhered at once. In order to test the effect on the eggs of not introducing the hand, about two quarts of eggs were impregnated in a galvanized iron pail. The water was added slowly and the pail kept in motion. The eggs did not adhere to one another, but adhered in a layer one or two eggs thick over the bottom and sides of the pail. Without distrib- uting those eggs that had adhered to the pail, those in the center were removed, and 154, taken at random, were examined with results as follows: Pryarede esr. 90 Se Re TT as 15= 10¢ Mot. uipresnated . 00550.

About a quart of eggs was used, and they were examined shortly after being impregnated. They had not adhered to the pail nor to one another, and the percentage of injured eggs did not appear to be more than five. Unfortunately, the eggs 36 were afterwards mixed with others and the whole lot roughly handled before an opportunity was had of making a careful examination of them. The suspension of opera- tions shortly after this prevented a repetition of the ex- periment. It is to be noted that when the eggs are permitted to adhere to the pail and to one another, so that the percentage of those injured is large, the percentage of those impreg- nated is also greater. The same method of handling that reduces the percentage of injured eggs reduces also the per- centage of those unimpregnated. From the two causes about 45% of the eggs examined could never have developed. Since the percentage of eggs lost during the present year is estimated at 40, there remains 15% still to be accounted for. A lot of eggs, 45% of which are dead, requires much more handling than would be the case if all were sound. Such a lot of eggs also invites the attacks of the fungus which spreads from the dead eggs to the living ones, and is likely to kill those in turn. In such a lot many living eggs become clogged among the dead ones, and are probably either smothered or poisoned. In short, if the loss of eggs which takes place at first from mechanical injury and lack of impregnation can be stopped, it is fair to expect that the subsequent loss will be much reduced. THE STURGEON ; SOME EXPERIMENTS IN HATCHING. By Hoyr Post, oF MICHIGAN. Of the numerous fish which abound in the great lakes and deep rivers that surround the State of Michigan, one of the most valuable, commercially, is the sturgeon. Nearly every part of it is utilized in some way; the flesh 37 is eaten, either fresh or pickled, and when dried and smoked is sold as halibut. The bladder, which is large, is converted into isinglass and glue. The skin is sometimes tanned, and even the dorsal cord is cut and dried and used as food. Every bit of waste is tried out for oil. The head is cooked and eaten by the Indians. The roe is much the most valuable part of the fish. In the full-grown fish it weighs from fifteen to forty pounds and upwards, and at times constitutes nearly one-third the weight of the fish. From this caviare is made. The eggs are rubbed with the hand through a sieve until they are separated from the connecting membrane, and then a fine German salt is added, and the product thoroughly stirred with the hand and drained. It is then dried and packed in kegs for shipment. It is eaten as a relish and used as a substitute for meat in sandwiches. It is quite rich, and hasa decided fishy, oily, and salty flavor. It is highly prized by the Russians, and is said to be much used in fast seasons in Italy, Greece, and Turkey. It finds a ready market in this country in St. Louis, Sandusky, New York, Philadel- phia, and Pittsburgh. The sturgeon is taken largely in pond-nets, and a good many are caught by set lines in the narrow, deep channels that traverse the St. Claire Flats, near Detroit. A strong line is stretched upon stakes on either bank of these chan- nels, and from this depend many shorter lines to which are attached large hooks which rest on the bottom. The sturgeon, in rolling upon the bottom, becqmes entangled in these hooks and is captured with a gaff. The Michigan Fish Commission last year tried the ex- periment of artificial propagation of this valuable fish. A station was selected at Algonac, a small village on the St. Clair River, where a caviare factory was in operation. The fish that are handled there are caught principally in the channels of the St. Clair Flats by the Indians, Canucks- and half-breeds in the manner above described ; they are 38 towed by a tugina covered yawl from the places of capture —a distance of from three to ten miles—to the station at Algonac. In the early part of June a pen about forty feet square was made adjoining the factory, by means of an old seine, between the bank of the river and some old spiles which had once been part of the dock; this pen was from one to five feet deep, with sandy bottom, and a swift current of clear water swept through it. On June 6th six females were placed in this pen, and on the next day eight males, and on the 18th of June ten more were added ; but they did not do well in confinement, on account of the injuries they had received from the gaff when captured. On June 17th the fish commenced dying, and six were taken out, when it was found the eggs had become hard and baked, and were almost the color of gold. The milt of some of the males had shrunk to almost nothing, and in others appeared to have ripened some- what. On June 27th the remainder of these fish, having become very weak, were all taken out. Up to this time only six spent fish had been taken, though upwards of 4,000 were handled ; and none were captured that were ripe except two that were taken on the 20th nearby, in the North Channel. Of these two, one was nearly spent and the other was about half gone. The fish were but just alive. A male that was taken in the same catch was cut open and the milt-bags crushed into a tub containing about six gallons (say four inches deep) of water, and the half-spent female was laid across the tub and split next to the vent, and the eggs allowed to fall into the milt. The tub was then kept in motion in the water for three and one-half hours, until the eggs became pretty well separated and ceased sticking. Two tubs were used, and one man handled each tub, standing in the water above his knees. There were probably in all about 40,000 eggs, of which perhaps one-half were thoroughly separated and fertilized. 39 The fertilized eggs measure about forty-nine to the square inch, while the eggs in caviare go about sixty-eight to the square inch. These eggs were taken from the tub and put into about a dozen Seth Green shad-hatching boxes and placed in the river, harnessed together and attached at the upper end to the dock and anchored at the lower end, so as to float freely in a swift current of clear water of about twelve feet indepth. The temperature of the water was about fifty- nine to sixty-one degrees. For two days the eggs appeared to be doing well, but on the third day a fungus began to appear and spread rapidly, and thereafter it was difficult to tell the good eggs from the bad ones; on the fourth day the good eggs showed a brown side with a yellow streak through it; on the fifth day the young fish could be seen in the egg; on the seventh day motion could be detected, and on the eighth day hatching commenced, and was com- plete on the ninth day. The number hatched was estimated at from eight to ten thousand, and they were released in the river at the place of hatching, on July 2d, the twelfth day after they were taken. The eggs are a rich, dark bronze color, and are very tender, so that they will not bear hard stirring or rough usage ; this necessitates great care and patience in the first handling. The milt seemed to form a heavy coating on the eggs that were fertilized, which would stick the egg to everything it came in contact with. The adhering of good eggs to each other did not seem to hinder hatching, but wherever a dead egg came in contact with good ones it destroyed them all; and many good eggs were lost in removing the fungused ones. Afterwards, about July 5th, eighteen sturgeon—twelve females and six males—caught in nets, were procured at La Butte’s Point, in Canada, above Detroit, and were towed by row-boat in a crate about ten or twelve miles toa . 40 large fish-pond made of sheet piling, in Detroit River, at the Fort Wayne fishery, below the city of Detroit. This pond was in clear water, in the current, and detached from the shore, with soft bottom and of an average depth of about six feet. The fish arrived in apparent good con- dition. One small male, supposed to be about four years old, was killed to ascertain the growth of the milt, which was found to be well developed. A small platform or slide was erected at one end of the pond. and a small seine was used to handle the fish. They were carefully handled twice a week for more than two months without any suc- cess. No eggs were taken from them. Finally, upon opening a female, the eggs were appar- ently blasted. The milt of the males also appeared to have dried up or shrunk away. A male and a female were left in the pond until October, and at that time, when taken out, the female had shot her eggs, and appeared in good shape, with new eggs forming. The facts stated in this paper as to the experiment in hatching sturgeon eggs are principally derived from Mr. Aaron W. Marks, the assistant superintendent in charge of the work. He was formerly a pupil of Seth Green, and assisted him in about the year 1876 in, perhaps, the first successful hatch of sturgeon in this country. That hatch was made at New Hamburg, on the Hudson. The number of eggs taken was about 200,000, and they were taken from a single fish. The hatch was about 140,000. The manner of treating the eggs was about the same described above, as adopted at Algonac last year. Further experiments in this line will doubtless be made in Michigan the coming season. 4] THE ORIGIN OF ARTIFICIAL FISH CULTURE IN THE UNITED STATES.
