By N. B. SCOFIELD. As the question of removing the restrictions on the Chinese shrimp or bag nets periodically arises at each session of the legislature, it is thought best to give a brief history of the shrimp fishery in the state and to describe the fishery as it has existed in the past in order that those who care to can learn of the great destruction to young fish and young shrimps by the Chinese method of fishing. The only account of the earliest shrimp fishing operations in the state is supplied by Mr. A. Paladini, the venerable fish dealer of San Francisco. He came to San Francisco in 1869 and engaged in shrimp fishing. There were eight boats on San Francisco Bay engaged in this 42768 •j CALIFORNIA PISH AND GAM] business, each boal manned bj white men. They easily caughl enough shrimps to Bupply the demand, besides many flounders, sole, tomtod, etc., for the fresh fish market. Pish and shrimps were very plentiful in the bay a1 the time. The shrimps caughl were the same species as now, bul were much Larger than those caughl in Later years during the intensive fishing by the Chinese. This Later reduction of the Larger and older shrimps as aoted by Mr. Paladini is good evidence that the sin-imps were being subjected to overfishing. The early fishing of the eighl boats of Italian fishermen was carried OD with small-meshed seines, sixty feet Long and eighl feel deep, with a bag at the center. They used the nets iii the deeper water of the hay for there the catch was liver of young fish and of the small unmarketable shrimps. The manner of fishing was to lay out the net. then anchor the hoat down the tide and pull the net along the bottom toward the hoat by means of lines, always pulling with the tide. The net was pulled directly into the boat. The} would make from three to five hauls on each tide ami they caughl from fifty to seventy-five pounds of shrimps at a haul. This method of fish- ing was far less destructive tit young fish than that employed later by the Chinese. They could fish in deeper water, where young fish and young shrimps were fewer, and unlike the Chinese nets which are set during the whole tide and kill practically all the young fish caught, they were in the water only a short time — Less than one-half hour and the small per cent of young fish caughl were still alive and could be returned to the water. The shrimps thus caughl were sold fresh at the Long Wharf. Little thought was then taken as to whether a method of fishing was destructive or not and there were few laws protecting fish, for it was thoughl that the supply of fish in the bay and rivers was inexhaustible. The Chinese had for some years been in the fish- ing business and with their destructive methods of fishing hail already begun the extermination of the Sacramento perch and with their fiendish sturgeon lines had inaugurated a method of fishing that has resulted in the commercial extinction of that valuable fish which in the early days was here in apparently inexhaustible numbers. In 1871 the Chinese began fishing for shrimps and introduced the destructive Chinese shrimp net. They made enormous catches with these fine-meshed set nets and found it profitable to supply the markets with shrimps at one and one half cents per pound. The original eighl Italian shrimp boats were driven out of business and since that time shrimp fishing has been almost entirely carried on by Chinese. Prom the very start the Chinese dried the hulk of their catch for the Oriental export trade. The shrimp fishery quickly grew to Large proportions and fishine- was carried on al many places in San Francisco Bay and in Tomales Bay in .Marin County. The firsl printed account of the shrimp fisherx is contained in Vol. II of " History and Methods of the Fisheries " by Goode, printed in 1885 by the United states Bureau of Fisheries. A more extensive investiga lion of the fishery was made by the author for the California Fish and Game Commission in 1897. A subsequent invest Ration was made by the author in 1!>H>. There has always been serious objection to the Chinese method of catching shrimps, and much of the Legislature's time lias been taken up by listening to discussions between those who would CALIFORNIA KISII AND GAME. d conserve the fisheries resources of San Francisco Bay and rivers, on the one hand, and the interested defenders of the Chinese, on the other. Closed seasons were finally resorted to and the drying of shrimps was prohibited, without greatly reducing the destruction of young fish. At the 1910-1911 session of the legislature the use of Chinese shrimp nets was prohibited entirely. The shrimps had been so reduced in numbers that it was found unprofitable to catch them by the method formerly employed by the Italians. It was also found to be unprofitable to employ the shrimp trawl which was in successful use on Puget Sound. In 1915 the legislature removed the restriction against the Chinese net in South San Francisco Bay on the ground that in that part of the bay the destruction to young fish was much less than in the upper bay and for the further reason that in that part of the bay the kinds of fish destroyed did not include the young of herring, smelt, shad and striped bass as was the case in the upper bay. At the 1916-1917 session of the Chinese shrimp fishing junk on San Francisco Bay. Photograph hy H. B. Nidever, legislature a very strong effort was made to reestablish the fishery in the upper bay by those who would be benefited in the way of rents, selling of supplies, etc.. and by those who would have the picturesque industry for sentimental reasons. As this effort is sure to be resumed at the 1918-1919 session it is believed an intimate description of the industry as it existed up to the year 1910 will be of interest, especially as tlie Chinese now operating in South San Francisco Bay are using identically the same methods, with the single exception that they do not catch so many young fish in that part of* the bay and the young fish caught are not of the more valuable species. Gamps: The fishing has been carried on by what has been termed "camps." Each of these camps is a separate unit, which has its own boat, wharf, boiling vat and drying ground, separate living quarters and storehouses. Although one Chinese company may have owned or controlled several camps, even side by side at the water's edge, they I C \l ll'OKM \ FISH \N|. C, \MK. did not co-operate in an\ way. The camps were very similar in charac ter, consisting of ;i group of small, rude shacks of rough, unpainted boards, placed oear ill Ige of the water, with a rough wooden wharf tunning out into the shallow water <»n hand-driven piling which answered as a landing place for the camp's junk. Very few of the camps could be approached a1 Low tide, for which reason they usually fished the flood tide in order that they might more easily bring their catch to the Landing. The shacks which constituted, the living quarters and storehouses were, in the majority of cases, crowded on a oarrow beach between t he water and the hills. The dry grounds of each camp covered about an acre of the slope of the hills for the wanl of a better Fig. 2. Scenes on board Chinese shrimp junk on San Francisco Bay. Photographs by H. B. Nidcver. place, and were usually floored with boards. In two or three of the camps the drying ground was partly on a platform built out over the water. In 1897 there were 26 camps operating on San Francisco Bay and in 1910 this number had been reduced to 19. The camps on Tomales Bay were abandoned some years prior to 1897. Of the 19 camps found in 1910 three were in the cove just above South San Francisco, five were at Hunter's Point, four in Contra Costa Counly south of Point San Pablo in Marin County. The three camps near South San Francisco were controlled by one company, the Fook On Lung Company of San Francisco. They furnished no fresh shrimps for the market but dried their entire catch. Their fishing ground was in Alameda County about three miles east of San Bruno Point. Each CALIFORNIA FISH AND GAME. 0 of their three junks used sixty Chinese shrimp nets such as are described under "Methods of Operating Nets." Two of the five Hunter's Point camps, located on the south side of the point, were owned by the Quong Lee Chong Company of San Francisco. Each of the two boats fished forty nets and they dried their entire catch. Their fishing ground was about a mile off shore, a little west of south from the point, which brought them within San Francisco County. Of the three camps on the north side of the point, the two camps nearest the point were controlled by the Fook On Lung Company, also known as the California Shrimp .Company. The third camp on the north side of the point belonged to the Union Shrimp Company, a Chinese company of San Francisco. The three last-named camps sent part of their catch to the fresh shrimp market and dried the rest. They fished in Alameda County a mile south of the Alameda mole. The four Red Rock camps were located in a cove on the Contra Costa shore about two miles to the south of Point San Pablo. These camps belonged to the Union Shrimp Company of San Francisco and their four boats fished just to the north of Red Rock in water from four to six fathoms deep. This depth is greater than that fished by any of the other boats and it was not possible for them. on account of the depth and tide, to use more than thirty nets to eaeli boat. Part of their catch went to the fresh market but the main part was dried. Of the seven camps near Point San Pedro, Marin County, one was situated in the first cove to the south of the point near the rock quarry. It was an independent company drying most of its catch but selling a few to the Union Shrimp Company, for the fresh market. Their boat fished about one-half mile southwest of the point. The next camp to the north of the point belonged to the Union Shrimp Company. Its boat fished about one-half mile off shore and sometimes across the channel in Contra Costa County. This camp sent part of its catch to the fresh market but dried most of it. One-half mile further to the north was a Quong Lee Chong Company camp and next to it in the same cove a Quong Sing Lung Company camp, while just to the north in the next cove was a second camp of the Quong Sing Lung Company and next to this two other Quong Lee Chong camps. These last five outfits named, dried their entire catch and their five boats operated sixty nets each. They fished far out on what is known as the "Petaluma Flats," the furthest boat fishing one-half mile due south of the outer Petaluma Creek Beacon, the other near but to the southwest. All five fished within the county of Marin. The following description of the boats, nets and fishing methods applies to the industry today just as it does to the industry as it existed twenty years ago: Boats. The boats used by these camps are of Chinese pattern and make. They vary in size, but the majority are about fifty feet long and twelve feet beam, with rounded bottoms without a keel, and with square sterns and rather blunt bows. They have one mast which carries a Chinese cleated sail. About fourteen feet of the stern is decked in and constitutes the living quarters of the crew. This com- partment is entered through a small sliding hatch and there the five men of the crew cook their meals, eat and sleep. Just forward of this is the open shrimp locker, about twelve feet square, for holding the catch, and next forward is a looker of similar size for holding the nets. (• CALIFORNIA PISH AND GAME. The remaining space forward is used for lines and gear. (>n the deck between the crew's quarters and the shrimp locker is :i crude wooden windlass placed horizontally and with four wooden spokes projecting by which it is turned by the hands and feel of the operator. From the drum of this windlass a line pusses forward through a notch in the elongated how posl of the boat. This windlass and line is used to lifl the series of nets from their fishing position at the bottom of the bay. The boats are of sufficient size to carry sixly wet nets and ten to twelve tons of catch. Nets. Eaeh separate net is constructed in the shape of a funnel. They are usually thirty-two feet long, with the larger opening or month about eighteen feel in diameter, from which the net tapers to the narrow opening a loot and one-half in diameter at the end of the sack. This narrow or cod end of the net is closed |>\ a st ring which can be untied to remove the catch when the nets are pulled up. The nets are made in China from a very strong and durable twisted grass-like fibre. The net has a mesh of three and one-half inches near the month bu1 the size rapidly diminishes toward the small end until the sack has meshes of one-half inch or lesss This small-meshed end of the net, which has to sustain the weight of the catch when the nel is pulled from the water, is usually reinforced by a net of coarse twine placed around the outside. In making the webbing of these nets square knots are usc{] instead of the usual knot used by fishermen the world over. The nets are dried and tanned ahont once a month and with care they will last a year. Their cost is ahont $25 Mexican in China. After paying freighl and other charges and adding the hanging line around the larger opening they cost here ahont the same amount in gold. Method of (>/>< mlintf Nets. Each junk operates a set of nets, thirty to sixty in number, which are set side by side at the bottom of the bay with their larger openings or mouths open to the current. The nets are held in place by a series of brails or speaders — 2x.'{ inch sticks of pine five feet long— each of which is held lo'a short stake driven in the bottom of the bay by a line from either end. of sufficient lenglh to permit of the brails with the nets attached being lifted to the surface during the slack water between t ides, without detaching them from 1 he stake. The stakes to which the brails are attached are driven t went y-l'onr feel apart across the current in the muddy bottom of the hay in a very ingenious manner. For driving these stakes a very long tapering pole is used with a foiir-inch iron pipe fitted on the larger end so that a hollow end of the pipe projects a couple of fee) beyond the end of the pole. Selecting a stake with lines and brail attached, ils head is inserted in the hollow end of the pipe where it fits loosely bid is kept from falling out by holding on to the brail lines while the pole is held in the vertical position over the spot where it is to he driven. The pole with the stake in place is then lowered from the boat until the stake is pressed into the mnd. The stake is then driven home by repeatedly lifting the pole a short distance and then lowering it forcibly. The stakes are driven twenty-four feet apart across the current so thai each brail when it is in position with nets attached will stand vertically on the bottom in each space between the mouths of the nets. Attached in this way. the nel months instead of being circular are now rectangular in shape, the opening being twenty-four feet across and about four and one-half feet CALIFORNIA KISII AND GAME. / deep. To remove any uneven strain on the nets and 1<> prevent their being carried away by the swift tide, a heavy anchor or stake is placed about fifty feet out from each end of the row of stakes and in line with them, from which runs a heavy line which is tied with a clove hitch to the center of eacli of the brails. By anchoring this heavy line in line with the stakes and sufficiently far out. the arrangement does not inter- fere with lifting the brails and nets to the surface of the water when the catch is to be removed just before the slack water at the end of the tide. Besides the heavy anchor line running from brail to brail, there is another and lighter one, the buoy line, which facilitates in lifting the nets. This line, when the nets are set in fishing position, extends from a floating buoy at one end of the string of nets to the first or end brail, to which it is tied by a bight about a foot from its top. From thence it runs to each brail in succession until the last brail at the end of the string of nets is reached, from whence it extends up to another buoy on the surface of the water. This buoy line is in place only when the nets are set. The nets are fastened to the brails < \\ |! • • ■•Vjp pjp 1*"-— 5^5l^P^^v~'* 1 - — ■Lmm"- 1 ** ' mmr —^ Fig. 3.

Scofield. and the buoy line is attached just after the turn of the tide before the current has become swift. The force of the current swings the series of nets down onto the bottom where they are held by the brail lines to the row of stakes, reinforced by the heavy anchor line. Here they are left during the entire tide, the time varying from four to eight hours, with their mouths open against the tide while the current carries the shrimps and young fish into them. With this manner of fastening the nets they can be used on either a flood or ebb tide. When the nets are to be lifted at the end of the tide after the force of the current has slackened sufficiently, an end of the buoy line is taken at one of the buoys, passed through the notch in the bow post of the boat and thence carried back to the windlass, where it is reeled in by one man, thus bringing the first brail to the surface and lifting the net with it. The other members of the crew detach the net and the buoy line from the brail while the man at the windlass reels up the next brail. Thus the nets are detached in succession, the catch being emptied into the shrimp locker and the nets placed in the net locker. The 8 < Al.iroKXJA PISH AND G \All. Chinese are verj experl in handling the nets and work rapidly, each man with a particular duty to perform. The time in which the nets have to be lifted is limited usually to about half an hour. They can not begin sooner for the nets can not be lifted when the currenl is strong. If they arc not gotten out before the tide turns the nets begin to swing the other way and they become tangled ami the catch is lost. When tides are so strong that there is danger of carrying the nets away they reduce the currenl pressure by tying the upper edge of the nets farther down on the brails. If the tides are exl remely swift t hey reduce the number of nets. Shrimp Drying. After the nets are all lifted the junk sails back to the dock at its camp, where the catch is carried in baskets.

This vat is about four by eight feel and eighteen inches deep, with wooden sides, the bottom being of sheet iron bent up around the sides. It is built in with bricks and mud and to heat the water both wood and coal is used. Fresh water to which rock salt has been added is used in the vats. The shrimps, together with the fish caugh.1 with them, are poured in. ten or twelve baskets at a time, and boiled from ten to fifteen minutes. They are then dipped out with a strainer and put into baskets to be carried to the drying ground. Ilei-e the shrimps and fish, the latter usually small and delicate with t!ie flesh boiled from the bones. ;i re spread out together to dry in the sun.

The whole mass is then carried to a shed where it is run through a small fanning mill to separate the Loose shells, fish bones and pulverized fish flesh from the heavier shrimp meats. By screening and hand picking the shrimp meats are divided into two grades, the unbroken meats in one and the broken meats in the other. They are then sacked. 280 pounds to the sack. The shells fish bones and fish flesh, and all fine particles and dust are saved and pu1 in sacks. 810 pounds to the sack, and sold for use as a fertilizer. The loss in drying is about 65 per cent, and for each pound of shrimp meals there are two pounds of fertilizer or "shells." Drying Fish. The amount of young fish taken in I he Chinese nets is always large, varying from 10 to 75 per cent of the entire catch. Form- erly large quantities of. these fish were dried. The larger fish were picked out and hung on strings to dry while the very small fish, princi- pally the young smelt (Osmerus thaleichthys) were dried on trays which had been covered with discarded net webbing. The small fish were separated from the shrimps by dumping a basket of the catch in a small vat of cold water where the live shrimps sank to the bottom, thus allowing the small dead fish to be easily skimmed from the top. After being prosecuted for catching young fish they ceased to dry the small fish and boiled them with the shrimps to get rid of the evidence as quickly as possible. They were nearly as valuable as a fertilizer as they Avere as a food product. There has always been this incentive to catch the young fish and experience has shown that it is impossible to operate the Chinese net without catching great quantities of immature Jish, thus causing great damage to the fisheries of the bay and rivers. Fresh Shrimps. In the camps that sent fresh shrimps to the markets they had a special shed at the wharf where part of the catch was taken and the larger shrimps screened out by hand and all fish, seaweed and dirt carefully picked out. The shrimps for the market were boiled before the rest of the catch, in the same way as were those to be dried except that less salt was used and they were not boiled (piite so long. After boiling, the shrimps were spread on matting on the sorting room floor where they could cool and the surplus moisture evaporate. They were then placed in baskets and conveyed by power launch to San Francisco. Three Species of Shrimps. Three species of shrimps are taken in San Francisco Bay. Fully 90 per cent of them are of one species, Crago franciscorum. The remaining 10 per cent is made up of the two species. Crago nigricauda and Crago nigrimaculata. The shrimps drift back and forth along the bottom of the bay with the tides but have the power in some measure to select their environment, for in the winter time when the fresh water is entering the bay in larger quantities they move farther down the bay. In the summer when the blue sea water encroaches on the flats they move farther up toward the river mouths. They appear to go on the shallower Hats when they are carrying their eggs. The smaller individuals are found mostly in shallow water and in the deeper and swifter water more large ones are found. They have a wide range, however, for they are found in the deepest water as well as the shallowest and can be found in water per- fectly fresh as well as in pure sea water. Very little is known about their life history. Females may be found carrying eggs attached to 2 -12760 1(1 CALIFORNIA FISH \.\|> Q \.\IK. her swimmerets al ;ill spinous of the y>-.n-.

Scofield. fresh shrimps marketed has increased each year until now the amount is equal to that of any former year when shrimp fishing was at its height. The shrimps have increased in numbers in all portions of the bays, as also have the number of small fish, especially the young of the striped bass. It has now become profitable to use the shrimp beam trawl which, towed with the tide, catches the shrimp with a very small per cent of young fish. As illustrative of the damage done by the Chinese nets in former years the following is quoted from my note book of 1897 : "The average catch per day for each boat at the San Rafael (Point San Pedro) fishery, during the last two weeks of duly, was seventy baskets, each basket weighing about ninety pounds, making in all six thousand three hundred pounds. The average number of boats out each day was seven, making in all a daily eateh of forty-four thousand one hundred pounds. For thirteen days (the time they were under continual observation) this number is swelled 12 CALIFORNIA PISH \M» GAM] to six hundred sixty one thousand, five hundred pounds. One-half • of this catch consisted of small fish, the principal species being smelt, California anchovy and sculpin. The small smell, two and one-half to three and one-half inches long, were very abundant, making up over one-fourth of the entire catch. The estimated amount of these young smelt taken in the hist fifteen days of July is 165,375 pounds, or about 16,537,500 small fish. When the nets are broughl to the surface of the water, these small smelt are dead, so that to throw them back would do no good.'" Later, in the year 1!>1<). we made the following notes: "Oct. 25, 1910: Visited two San Pedro Point boats as they lifted their nets. One had 30 per cent of young fish, mostly smelt and sole. They also had a good many undersized female edible crabs, which were alive, but they had not attempted to throw them back. The other boat had 20 per cent of young fish. Oct. 28, 1910: Six boats out of San Pedro Point. Ming's boat had eighty baskets on this tide, of which 30 per cent was fish, mostly young smelt, young sole, and tomcod. One boat had forty baskets, two boats fifty baskets each, and the remaining two had seventy-five each. The amount of young fish was about 20 per cent. Ming says he uses forty nets and has averaged seventy bas- kets a day for September and October. The five camps above him use sixty nets each and their catch is much larger. Oct. 29, 1910: Again visited San Pedro Point boats. Five boats out. The catch the same as yesterday. Three boat crews have been arrested in the last few days for catching young fish, but when visited yesterday and today they made no attempt what- ever to throw back even the few fish that were alive. Wing had used a screen to get out the fish, but his catch was still 30 per cent fish. Their nets were all set wide open, as the tides are not so strong now." The above notes are selected to give a conservative idea of what the average catch consists in upper San Francisco Bay. The greatest damage is done on the shallow San Pablo Bay flats. During the winter months large numbers of small striped bass are killed in the nets. The boats which fished below San Pablo Bay in the deeper water near Red Rock and the Stone Quarry caught smaller quantities of young fish than those above, but they caught more of the young striped bass than any others. The late increase in the number of striped bass is undoubtedly in large part due to the abolition of the Chinese nets in the upper bay, and if we value that fine food and game fish the destructive shrimp nets should be kept out. The Chinese operating in South San Francisco Bay catch fewer young fish and the varieties caught are not of the valuable species The lower bay can easily supply the fresh markets without serious injury to any of the other fisheries. But even there, the nets should be prohibited as soon as a less destructive method of shrimp fishing can be developed. CALIFORN I V FISH AND GAME. L3 THE FISHES OF THE CROAKER FAMILY (SCIAENIDAE) OF CALIFORNIA. By EDWIN CHAPIN STARKS, Stanford University. The fishes of this family have a peculiar silvery skin thai is unlike the bright, burnished silver of some fishes, the herrings for instance. lnii suggests rather frosted silver. The head is closely covered with scales, more or less irregular in size and shape, and the pore-bearing scales of the lateral line extend onto the caudal fin. The bones of the skull are variously excavated with tunnels and open channels (cav- ernous), and the chin is usually provided with large pores or barbels. Two dorsal fins are present; the first composed of spines and more or less triangular in shape. The anal fin has one or two spines, sometimes very small and slender or sometimes the second one is very much enlarged. The croakers are carnivorous fishes rather distantly related to the basses. Many of them make a peculiar noise from which the common names of croaker, grunter, and drum have been derived. The noise is supposed to be made by forcing the air (or more properly, gas) from one part of the swim bladder to another. The species are numerous on sandy shores, and are most abundant in warm and tropic seas. At Panama, for instance, there are between 40 and 4"> representatives of this family. Of the eight that occur on our coast only two are found in abundance as far north as San Francisco. Most of the others occa- sionally stray that far. but are common only on the southern coast. All of them are very good food fishes, and some are classed as game fishes. The common or popular names of these fishes are even more mixed up and poorly applied than usual. Gynoscion nobilis, the "sea bass," is not a bass, and Seriphus, sometimes called the herring, does not even remotely resemble the herring. The young "sea bass' is known as "sea trout." No possible stretch of the imagination could make it suggesl a trout, and having wrongly called its parent a bass, to call it a trout is a xwy good commentary on how loosely common names are used. Genyonemus, the fish thai is usually known as the kingfish, is some- times called "lomcod"' on the southern California coast, it resembles a, tomcod as little as Seriphus, the queenfish, resembles a herring. When Genyonemus, the kingfish, is called "tomcod" the name kingfish is transferred to Seriphus, the queenfish. or white croaker. Gynoscion parvipinnis, a close relative of the "sea bass." is sometimes called "bluefish," though it has nothing whatever in common with the famous bluefish of the Atlantic. The names croaker, roncador, and corvina are not at all consistently applied, but are shuffled back and forth between various of these fishes. Hence in the use of vernacular names among these or any other fishes the reader is again cautioned that there is no constancy nor rule for their application, and he can only be sure of definitely indicating a given fish by using its scientific name. Though such names will probably never be used by people al large, and certainly not by unlet- tered fishermen, the scientific name is nevertheless the one true name for a species, and a name I hat will be recognized by scientific men in all countries 1he world over 14 CALIFORNIA PISH AND GAME.

CALIFORNIA FI8II AND GAME. 15 Snout : The part of the head that lies in front of the eyes except the lower jaw. Ventral fins: The paired fins on the lower part of the breast; close under the pectorals in these fishes. The Queenfish, or White Croaker (Seriphus politus). The length of the base of the second dorsal fin is about equal in length to the base of the anal fin. The tip of the snout is rather sharp and the tip of the lower jaw projects beyond it when the mouth is closed. The mouth is long and narrow, and the maxillary does not quite reach to vertically below the hind border of the eye. The dorsal fins are well separated, and the .spines of the first dorsal are slender. The color is bluish above with the sides and belly bright silvery, the tins yellow, and the base of the pectoral dusky. Fig. 6. The queenfish (Seriphus politus). On the southern California coast this fish is ridiculously called her- ring, a name that should decidedly be discouraged, for it has nothing in common with the herring, is not related to it, and does not even look like it. It also in the same region shares with Genyonemus lineatus, the name of kingfish. The latter is almost universally so known and hence has the best right to the name. This fish reaches a length of about a foot, and is an excellent pan-fish. It is salted and smoked to some extent in southern California and marketed as herring. It is common on sandy shores of the southern and Lower California coasts, and has been taken as far northward as San Francisco. The White "Sea Bass" (Cynoscion nobilis). The snout is sharp and the tip of the lower jaw projects beyond it when the mouth is closed, while the length of the base of the second dorsal is three or more times the length of the anal base. The length of the pectoral fin is more than half the length of the head, and the tip of the pectoral reaches about to opposite the tips of the ventrals. There are no greatly enlarged teeth pointing backwards at the front of the upper jaw. The mouth is large and the maxillary nearly or quite reaches to vertically below the hind border of the eve. The caudal fin 16 CALIFORNIA KIS1J AND UAME. is concave behind. Very fine dark points are everywhere dusted over the silvery color, making it more or less dusky bluish. The inner sur- faces of the pectoral and ventral fins are dusky. Fig. The while- sea bass (Cynoscion nobilis). Though lids fish is only distantly related to the bass, it is in ( 'alifornia almost universally known as the sea bass or white sea bass. On the Atlantic coast fishes of this group are known as weakfishes. This species is one of our most valuable food fishes, reaching a weight of 90 or more pounds, and having firm white flesh. It is found in con- siderable abundance along the California coast and southward to Lower California. It has been reported as far north as Puget Sound. The young has dusky bands extending down from the hack onto the sides. Fishermen call the small ones sea trout. The California "Bluefish" (Cynoscion parvipinnis). As in the white sea bass the snout is sharp; the tip of the lower jaw projects beyond it when the mouth is (dosed ; and the base of the second dorsal fin is much longer than that of the anal fin. It may be known from the white sea bass by (he pectoral fin being less than half the length Pig. 8. The California bluefish (.Cynoscion parvipinnis). of the head, and its tip qoI nearly reaching as far back as the tips of the ventrals. It is also distinguished by having one or two long sharp teeth pointing backwards from the middle of the upper jaw. The dor- sal tins are close together. 'Idle color is steel blue above and silvery on 1he lower parts and sides. This fish closely resembles the white sea bass — in fact it is not recog- nized as different bv many lishennen. It does not reach as large a size., CALIFORNIA PISH AND GAME. 17 probably not exceeding a couple of feel in length, and it is said to be much inferior to it. Its flesh is soft and it does not bear transportation well. It is found from southern California southward along the coast of Lower California. The name bluefish as applied to this species probably is on account of its color, and not because it is thought to be the same as the famous bluefish of the Atlantic. The latter is a very different fish, not at all related to this species. The Yellowfin Croaker (Umbrina roncador). This fish may be known from its relatives by a short fleshy barbel. or appendage, that projects from the chin, and, in addition, by a large thick spine at the front of the anal fin. The enlarged spine is the second anal spine, there being a very short one in front of it. Its snout is blunt and projects over and above the tip of the lower jaw. The mouth is nearly horizontal, and the maxillary reaches to under the middle of the eye. The edge' of the bone that bounds the cheek behind Fig. 9. The yellow-fin croaker (Umbrina roncador). (preoperculum) is set with fine spines. The spinous dorsal is triangu- lar in shape but rounded at its upper angle at the points of the first spines. The pectorals are rather short and do not reach as far back as the ventrals do. The caudal is concave behind; and the upper lobe is longer than the lower. Brassy and golden reflections overlie the silvery color. The back is bluish, and over the back and sides are many wavy dark lines that extend upward and backward following the rows of scales. The fins are mostly yellow. This fish reaches a length of 15 or 10 inches, and it is rather common on the southern California coast. Its range extends southward into the Gulf of California while an occasional one strays northward as far as San Francisco. It is a very good food fish, and is caught in considerable abundance by the anglers on the piers and beaches of southern Califor- nia. It is a very handsome fish when it is first drawn from the water, but its iridescent colors soon fade. The California Whiting or Corvina (Menticirrhus undulatus). This is a well marked fish that may be known by a fleshy barbel, or appendage, that projects from the chin, the first dorsal spine longer than 3 42789 L8 CALIPORN] \ PISH AND (i VME. the others, making the tin sharply pointed above, and the caudal fin with its lower angle rounded and its upper sharp. The barbel at the chin is longer than in the yellow-fin croaker. It may be known from thai species at once by its lacking an enlarged spine at the front of the anal. The upper jaw projects considerably over the lower, the mouth is hori- zontal, and the maxillary barely, or scarcely, reaches to below the Eronl edge of the pupil. The edge of the preoperculum is divided into tine points which are membranous and not bony spines as in the yellowfbi croaker. The pectoral is rather long and reaches to about the tips of Fig. 10. The California whiting (Mcnticcrrhus undulati the ventrals. The color is grayish with brighl reflections. On the back and side are many dark wavy lines that run upwards and backwards. The back sometimes lias faint dark bars crosswise to the body. This fish is rather common on sandy shores of southern California, and is known southward into the Gulf of California, while individuals are sometimes taken as far northward as San Francisco. It is a yen good food fish and reaches a length of 18 or 20 inches. The Spot, or Spotfin Croaker (Roncador stearnsi). This fish may be known at once by the large black spot at the base of the pectoral fin. It is not only on both sides of the pectoral, but is also somewhat on the body behind the pectoral base. As in most of the Fig. 11. The spot (.Roncador stearnsi). CALIFORNIA KISll AND GAME. 19 croakers, a Muni snoul extends over a horizontal mouth. The mouth is moderate in size, and the maxillary reaches to below the middle of the eye. The preopcreuluni is sel with fine sharp spines. The iirsl dorsal has stout spines and the second spine of the anal is enlarged, the first spine being-, as usual, small. The pectoral is as long as the head, and reaches considerably past the tips of the ventrals. The color is grayish silvery, lighter below. Wavy dark lines follow the rows of scales extending upwards and backwards. These are less conspicuous than in the yellowfin roncador. Two dusky streaks usually run back from the throat to the ventrals and thence to each side of the anal. This fish is abundant on the southern California coast, and, like most of the others, has occasionally been taken as far north as San Fran- cisco. It is of some importance as a food fish, and reaches a weight of 5 or 6 pounds. The Black Croaker, or Chinese Croaker (Sciaena saturna). The following combination of characters will identify this fish from its relatives: The snout blunt and projecting over the tip of the lower jaw; no barbel at the chin; the second anal spine large and thick; oo Fig. 12. The black croaker (Sciana saturna). black spot at base of pectoral ; the pectoral shorter than the head and not reaching to the tips of the ventrals. The month is small, the lower jaw closes within the upper, and the maxillary reaches to below the middle of the eye. The scales on the head are small, rough and uneven. The preoperculum has a membranous edge that is divided into very fine points which are scarcely noticeable without the aid of a magnifier. The dorsal spines are rather stout, but not nearly so stout as the second anal spine. The caudal is slightly convex, or with its middle rays the longest. The color is dusky with reddish coppery reflections. A pale band usually extends downward from between the dorsals to opposite the tips of the ventrals. This often fades with age. The lower parts are silvery but dusted over and obscured by dark specks. The side of the head is more brilliantly coppery color than elsewhere. The ventral fins are dusky or black. A black spot is present at the edge of the gill cover just above its angle. 20 CALIFORNIA MM I AND G \ Ml.. 1'liis iirsli lias not been reported aortli of Santa Barbara, tts range extends southward alonge the eoasl of Lower California.

The blunt snoiil projecting over the tip of the lower jaw; no barbel at the chin; no enlarged spine a1 the fronl of the anal. The mouth is rather oblique. The lower jaw doses within the upper, and the maxillary reaches to under the middle of the eye or ;i trifle farther. The edge of the preoperculum is membranous and without fine bony points. On each side of the lower jaw just behind the chin are several very small barbels, so small that they scarcely show withoul the aid of a magnifier. The spines of the dorsal are slender. The pectoral ends opposite to the very slender points of the ventrals, or reaches a little past. The caudal fin is slightly concave behind. Brassy reflections Fig. 13. The kingfish (Genyonemus lineatus). overlie the bright silvery color. Very faint wavy lines follow the rows of scales upwards and backwards. The fins are usually yellowish, and there is a small dark spot just behind the base of the upper pectoral '•ays. < l < This fish and the white sea bass are the only ones of this family that are found in any abundance as far north as San Francisco. It runs southward along the Lower California coast. It is commoner in sum- mer than in winter, and more abnndanl on the southern eoasl than the northern. It scarcely exceeds a foot in length, but its abundance makes it a food fish of considerable importance. When fresh it is a very good food fish, but its flesh is rather soft and it does not keep very well. It is sometimes called tomcod in southern California. This name should not be used, for it in no way, shape, nor manner resembles the tomcod. CALIFORNIA PISH AND GAME. 21 NOTE ON THE SAND DAB. By EDWIN C. STARKS. Through an oversight in the paper on flat-fishes that appeared in the last number of California Fish and Game the old name of soft flounder was used as a common name of the fish that has in recent years been known as the sand dab (Citharichthys sordidus). This name, sand dab, lias almost entirely supplanted the older name on our coast and for thai reason should be used. It is, however, one of those unfortunate names borrowed from another fish from another part of the world. The sand dab of the Atlantic coast (Hippoglossoides platessoides) has the best right to the mime, for it was first so called. It bears little resemblance to our sand dab. So in your copy of California Fish and Game please write sand dab in place of soft flounder. THE STICKLEBACK: A FISH EMINENTLY FITTED BY NATURE AS A MOSQUITO DESTROYER. By CARL L. HUBBS. Since it has been proved that malaria, yellow fever, and other dread diseases are carried by mosquitoes, there has developed a wide interest in these little insects, which hitherto had been regarded more as a nuisance than as a menace. Many studies have been undertaken in order to determine the best methods by which mosquitoes may be exterminated or at least greatly reduced in numbers. 'I'lie use of window screens, the draining of .swamps, and the oiling of waters, as well as the spread of natural enemies, are methods of control that have received attention with very notable success. For instance, the building of the Panama Canal has been made possible by the destruction of mosquitoes and the consequent control of yellow fever. A word as to the main methods of mosquito control. The use of screens does not eliminate the evil. The draining of swamps has been very successfully practiced in New Jersey, and is applicable to other regions where large, swampy tracts occur. The use of oil. which spreads as a film over the wafer, forms a sufficient control, but requires continued attention and expense, and can scarcely be applied to most ornamental ponds or reservoirs or to pools from which animals drink. There is thus need for other methods, and of these the spread of the natural enemies of the mosquitoes is by far the most import ant, These natural enemies are numerous, and the most valuable of them all for the purpose are fishes, which destroy the young stages of the mosquitoes as well as the adults when they alight on the surface of the water. Among the fishes extensively used in mosquito control, the little killifishes or topminnows may be mentioned, but there are others which can be strongly recommended. This short report is written to call further attention to the value of the stickleback (Gasterosteus) as a mosquito destroyer in California, particularly in the coastal regions. 22 CALIFORNIA PISH \M> GAME. FACTORS RENDERING THE STICKLEBACK AN EFFICIENT MOSQUITO DESTROYER. L. Tin stickleback uses mosquitoes as food. This poinl is to be proved firsl of all. The evidence is convincing. The stickleback has been seen snapping up adult mosquitoes tin-own into the water. Mos- quitoes are unable to breed in waters inhabited by sticklebacks. This conclusion, previously arrived al in regard to the stickleback and the salt-marsh mosquito of San Francisco Bay, has been rigidly tested out in many of the si reams from San Francisco south to the Mexican border. Only a few examples from the observations can be made here. In San Prancisquito Creek, near I\ilo Alto; pools were repeatedly found near one another and apparently similar except in this respect: in the one pool sticklebacks were plentiful, bul qo mosquito wrigglers could be detected, while in the other pool sticklebacks were absent, while mosquitoes were breeding in abundance. The swamps, pools and streams of the coasl region of San Luis Obispo and Santa Barbara counties appear as ideal breeding waters for mosquitoes, yet the people there enjoy unusual freedom from these pests and dangers. A study of the region makes it almost certain that these people have the stickleback to thank for the service thus rendered. But, even in these regions mosquitoes breed in abundance in the moun tain canyons into which the sticklebacks can no1 penetrate because of the sleep descent of the bouldery stream beds. The mosquitoes are forced back, however, into the mountains where there arc fewer people for them to torment In Mission Valley in San Diego sticklebacks are. for some unknown reason, entirely absent, but mosquitoes and gnats are very troublesome during the summer months. From the valley the mosquitoes arc blown up the canyons to the city on the mesa above. During the summer the surface waters of the San Diego River, which flows through Mis- sion Valley, are reduced to a series of pools. In these pools three introduced fishes, the golden bream (Notemigomus crysoleucas) , the bullhead (Ameiurus nebulosus), and the green sunfish (Lepomis cya- nellus) are generally abundant. It seems that the stickleback is more efficient in the control of mosquitoes than are these thr ther fishes together. During an entire summer's study of this problem. I never aoted ;i considerable number of either mosquito wrigglers or stieklehacks in the same pool together. Wherever the stickleback can penetrate, and they go as far as they can, the mosquitoes are effectively destroyed. 2. Abundanci of other food will not deter II" stickleback from feed- ing on lh< iin>s(j)iih, wrigglers. This conclusion is evident from field observations, and is confirmed by the size and structure of the fish: its mouth, small even for such tiny fishes, will not permit it to feed on large insect larva- such as those of dragon flies, which, by the way. upon emerging as the adult insect, feed upon the mosquitoes in the air. 3.
