Fish-passage research. Review of Prog- ress. 1961-66. By Parker S. Trefethen. Oc- tober 1968, 23 pp., 37 figs. ABSTRACT Results of accelerated laboratory and field exper- iments to investigate problems of anadromous fish passage at high dams are summarized. Studies were made on: the passage of adult and juvenile fish through large, medium, and small impound- ments; design and operation of adult fish-passage facilities at dams; mortalities of juvenile fish pas- sing through turbines and methods of reducing losses; collection of juvenile fish from rivers, streams, and reservoirs; transportation of juvenile fish; and the effect of the changing environment on passage and survival. Publications by the staff are listed. 255. Published in 1967. 256. Design of the fishery research vessel Oregon II. By Francis J. Captiva. April 1968, 27 pp., 10 figs., 21 apps. figs., 2 apps. tables. ABSTRACT This paper describes the United States Fish and Wildlife Service, Bureau of Commercial Fisheries research vessel Oregon II. The vessel has been de- signed for exploratory fishing and gear development studies in the tropical and subtropical portions of the western Atlantic, Gulf of Mexico, and Caribbean Sea. It will be 170 feet long, will have a mean draft of 12'/2 feet, and a beam of 34 feet. Two 800-horse- power engines will propel it through a single pro- peller. The vessel incorporates many innovations for ease, safety, and flexibility in gear handling. 257. Published in 1967. 258. Monthly mean charts sea surface temper- ature north Pacific Ocean 1949-62. By L. E. Eber, J. F. T. Saur, and 0. E. Sette. June 1968, vi + 168 pp. of charts. ABSTRACT This atlas contains 168 monthly sea surface tem- perature charts for the Pacific Ocean north of lat 20° S. The series extends from January 1949 through December 1962. Each monthly chart con- tains isotherms for intervals of 1° C and plotted values representing the density of observations by grid "squares" (about 86 nautical miles to a side). The data were taken from the marine weather observations stored in Punched Card Deck 116 at the National Weather Records Center, Asheville, N.C. The amount of data available per chart ranged from about 5,000 observations at the start of the series to 15,000 at the end. The observations were distributed more abundantly along trade routes and were generally sparse in tropical regions. Editing procedures exercised for quality control included rejection of erroneous values and the ap- plication of corrections to temperature values re- ported by ships which were determined to be syste- matically biased, relative to other ships. A nu- merical analysis technique, based on Carstensen's Relaxation Method, was used to obtain digital rep- resentation of the temperature fields. The isotherms were smoothed to reduce small-scale irregularities. 259-266. Published in 1967. 267. Progress in exploratory fishing and gear research in Region 2 Fiscal year 1967. By John R. Thompson.

Organizing the technical article. By F. Bruce Sanford. March 1968, 41 pp., 36 figs., 1 app. ABSTRACT No article can be more efficient than the outline from which it is written. This manual presents a technique for devising an efficient outline by either deductive or inductive reasoning, whichever is more appropriate to the circumstances. The technique is based on strict adherence to the principles of logic. 270-282. Published in 1967. 283. Heading-introduction technique. By F. Bruce Sanford. February 1968, 32 pp., 49 figs., 1 table. ABSTRACT Because of the vast increase in the scientific lit- erature, technical writers must help the reader grasp ideas quickly. For this purpose, headings and introductions are two of the most useful devices. Headings give the reader immediate insight into large blocks of information and help him digest them rapidly. Accordingly, they are an exceedingly val- uable aid to speed reading. Although headings are greatly helpful, they are not sufficient. They sometimes are ambiguous, they do not give reasons, and they look neither backward nor forward in the article — they are concerned only with the present. They therefore need supplemen- tation by introductions, which supply this informa- tion that headings, because of their brevity, cannot give. Introductions, in contrast to headings, are com- plex devices. They have five transitional functions; therefore, a complete introduction is made up of five parts. This manual defines the functions, names the parts, and shows how to use them. The manual thus is concerned with the heading- introduction technique, and its aim is to show how we can use this technique to help the reader grasp our idea fast. 284. Microbiological study of iced shrimp: ex- cerpts from the 1965 iced-shrimp symposium. By B. J. Carroll, G. B. Reese, and B. Q. Ward. May 1968, 17 pp., 8 figs., 1 table. ABSTRACT The presentations of studies of microbiology and summarized results of the abridged histological studies are reported. How marine and land bacteria cause spoilage under refrigerated conditions is ex- plained. Total numbers of bacteria, the changing makeup of bacterial populations, and organoleptic grades are given for pink, white, and brown shrimps through 14 days of iced storage. The effects of thorough washing are contrasted to those of average washing and the superior quality of well-washed shrimp in the second week of iced storage is shown by lower bacterial counts and the prolongation of grade. Practical recommendations, based upon ex- perimental observations or reports in the literature, are offered. A series of photomicrographs show how the tissues of shrimps of all three species dis- integrate in much the same way during 14 days of iced storage. A selection of suggested references for additional reading is provided. 285. Hypocholesterolemic effects of marine oils. By James J. Peifer. April 1968, 16 pp., tables 40 and 43. (No abstract.) 286.

Welch. June 1968, 14 pp., 7 figs., 1 table. ABSTRACT The surf clam, Spisula solidissima solidissima (Dillwyn), supports an important commercial fish- ery along the coasts of the Middle Atlantic States. The major portion of the catch has been taken off New Jersey since 1949. Surf clam fishing vessels, equipped with hydraulic jet dredges, take the clams from depths of 100 feet or less and land them the same day. Most of the catch is processed for use as food; a minor portion is used as bait for fish. The total catch in 1965 was 44.1 million pounds of meat. Surf clams are found in waters of oceanic salinity and sand or gravel bottoms from the low-tide to depths of 480 feet. They range from the Gulf of Saint Lawrence to Cape Hatteras, N.C. The sexes are separate. Spawning usually occurs twice a year. Eggs, under experimental conditions, failed to develop in salinities below 23 parts per thousand. Young clams may reach a length of 1% inches in 1 year. Mature clams are commonly 6 to 7 inches long. Surf clams are very abundant in some areas. Populations of 1 to 2 million juvenile clams per mile of beach have been found at Wallops Island, Va., and Sandy Hook, N.J. As many as 5 million mature clams per mile of beach have been washed up on Long Island, N.Y., by a storm. 289. Annual Report of the Bureau of Com- mercial Fisheries Radiobiological Laboratory Beaufort, N.C. For the fiscal year ending June 30, 1967. ByT. R.Rice. February 1968, 45 pp., 26 figs., 18 tables.

Report of the Bureau of Commercial Fish- eries Biological Laboratory St. Petersburg Beach, Florida fiscal year 1967. By James E. Sykes. June 1968, 17 pp., 17 figs., 1 table. ABSTRACT The major goals of the Laboratory are to explore the relatively unknown scope of biological produc- tivity in the coastal zone of the eastern Gulf of Mexico, to measure the effect of changes in that zone, and to develop methods of increasing estu- arine fishery resources. The report describes cur- rent research on projects in the Estuarine and Red- Tide Programs. The projects include studies of sediments and organisms in bay bottoms, plankton crops and fishes residing in and transferring be- tween estuaries and the Gulf of Mexico, toxicity of the red-tide organism, and experimental rearing of pompano in an impounded lagoon. A physical, hy- drological, biological, and sedimentological inven- tory of Florida estuaries is also in progress as part of a cooperative effort with the National Oceano- graphic Data Center and the States of Alabama, Mississippi, and Louisiana. 291. Sea floor topography of the central eastern Pacific Ocean. By Thomas E. Chase. June 1968, 8 pp., 19 figs., 26 app charts. ABSTRACT The offshore configuration of the floor of the eastern Pacific Ocean is presented on 26 topographic charts. A description of the methods and data used in their preparation is included with a general out- line of the major topographic features of the region. Innovations incorporated in the series of charts in- clude a search and evaluation of all existing data pertinent to the sea floor topography, contouring of the region in detail, and labelling of prominent undersea geological features. 292.

November 1968, 33 pp., 2 figs. ABSTRACT This atlas was prepared in response to interest expressed by the Gulf fishing industry for surface temperature information. It shows that sea surface temperatures fluctuate greatly seasonally and lat- itudinally with a yearly average of 77° F. This temperature fluctuation causes a seasonal fluctu- ation in the composition of the shallow-water fauna in the northern Gulf. The atlas also shows that surface temperatures extend deeper in winter than in summer and that upwelling occurs along the north coast of Yucatan during summer. In addi- tion to monthly maps for mean surface isotherms, monthly maps for maximum, minimum, and aver- age surface temperatures are also given. 301-302. Published in 1969. 293.

Proximate composition and sodi- um potassium contents of four species of tuna. By Neva L. Karrick and Claude E. Thurston. April 1968, pp. 73-81, 10 tables. ABSTRACT The following species of tuna were studied; al- bacore (Germo alalunga), bluefin (Thunnus thyn- nus), skipjack (Katsuwonus pelamis) , and yellow- fin (Neothunnus macropterus) . Data are reported for the light and dark meat of the nape, center, and tail sections of the fish. Vol. 4, No. 2. Use of sodium acid pyrophosphate to retain natural moisture and reduce struvite in canned king crab. By Robert Jones. April 1968, pp. 83-89, 1 fig., 3 tables. ABSTRACT Sodium acid pyrophosphate in varying concen- trations was added at two levels of pH to king crab during canning. Salt also was added. Adding 0.25 and 0.35 percent of sodium acid py- rophosphate increased the retention of moisture by almost 2 percent. Struvite either did not develop or developed very little during storage of the product for 1 year. Addition of pyrophosphate in concentrations greater than 0.35 percent adversely affected the taste of the product. Addition of pyrophosphate in concentrations less than 0.25 percent did not im- prove the product. Vol. 4, No. 2. Mechanized haul seine for use in farm ponds. By Kenneth L. Coon, Alfred Larsen, and James E. Ellis. April 1968, pp. 91-108, 14 figs., 2 tables. ABSTRACT Present methods of harvesting fish from farm ponds are time consuming, laborious, and wasteful of water. This paper supplies information on a mechanized system in which a haul seine and asso- ciated equipment are used to capture fish in farm ponds and a conveyor and associated equipment are used to load and weigh the fish into trucks for ship- ment to market. The mechanized seine works well both in ponds of small or large size and water as deep as 8 feet. Vol. 4, No. 3. Effect of special handling of had- dock on the postirradiation shelf life of had- dock fillets. By Vincent G. Ampola and Louis J. Ronsivalli. June 1968, pp. 109-111, 1 table. ABSTRACT Improved techniques for handling eviscerated haddock after capture resulted in superior quality of the fish prior to irradiation and a significant ex- tension in the post-irradiation shelf life of fillets cut from them. Vol. 4, No. 3. Sonic system for determining dis- tances between selected points of an otter trawl. By Leon E. French, Jr. June 1968, pp. 113-125, 9 figs. ABSTRACT Trawl gear is rigged with several sonic trans- ducers connected to a shipboard recording-type echo sounder by means of a special cable. Trawl dimen- sions are recorded continuously and simultaneously under a specially calibrated scale. Vol. 4, No. 3. Echo reflector for sonic measur- ing system on an otter trawl. By Leon E. French, Jr. June 1968, pp. 127-131, 3 figs. ABSTRACT Sonically measuring distances between points in an otter trawl during operation by use of trans- ducers and an echograph recorder presents prob- lems. For example, when the headrope height of an otter trawl is about one-half the wing-end spread, the head-rope and wing-end measurement traces ap- pear at the same location upon the recording paper. The simultaneous overlay of signals can be corrected by use of a sonic echo reflector to replace one of the wing-positioned transducers in the measuring system and by use of the echo-signal method instead of the direct-signal method. The echo signals, how- ever, are weaker than the direct signals. This paper reports on a test of three reflectors: plain wood, aluminum sheet, checkered aluminum. All three reflectors gave usably strong echo signals. The best quality signal was given, however, by the aluminum reflector. Vol. 4, No. 4. Effect of gamma radiation on thiaminase activity in freshwater fish. By- Richard A. Krzeczkowski. July 1968, pp. 133- 138, 2 figs., 5 tables. ABSTRACT Sensitivity to gamma radiation of the antime- tabolite thiaminase in whole fish was studied so that the potential usefulness of this radiation for con- trolling the activity of thiaminase in fishery products could be estimated. Although gamma radiation will partially inactivate thiaminase in the species stud- ied, its use for complete inactivation does not appear to be economically feasible. Vol. 4, No. 4. Relation of temperature, time, and moisture to the production of afiatoxin in fish meal. By Travis D. Love. July 1968, pp. 139-142. ABSTRACT Numerous instances have been reported in which moldly vegetable meals, when incorporated into feeds, have produced symptoms of acute toxicity in animals. The several toxin principles (aflatoxins) produced by the mold Aspergillus flavus have been isolated in crystalline form and chemically identified as lactones, epoxides, or hydroperoxides. Commercial fish meal has never been reported to contain aflatoxins. In this study fish meal was heavily inoculated with Aspergillus flavus, and the concentration of moisture was artificially increased to 18 percent. The meal developed aflatoxins after being held at 28°C for 35 days. The control meals, which had a normal moisture concentration of 10 percent, did not produce aflatoxins at any temper- ature studied, though they were heavily inoculated with Aspergillus flavus and held for 35 days. Vol. 4, No. 4. Variation in the fatty acid com- position of Pacific herring (Clupea harengus pallasi) oil in Alaska during 1964 and 1965. By Paul A. Robisch and Edward H. Gruger, Jr. July 1968, pp. 143-150, 9 tables. ABSTRACT Industrial users need knowledge about the vari- ability in the fatty acid composition of Alaska her- ring oil. Accordingly, oil from the 1964 and 1965 catch seasons was analyzed for certain of its chem- ical properties — individual fatty acid composition, total concentration of the saturated, monoenoic, and polyenoic fatty acids, iodine value, saponification value, free fatty acid value, and peroxide value. The individual fatty acid components varied to some extent. Ranges in the concentration of the monoenoic fatty acids for the 2 years did not over- lap; the average differed by 4.8 percent. Differen- ces in the averages for the saturated and polyenoic fatty acids were only 1.7 percent. Data on iodine value indicated that the total unsaturation of the oil was somewhat greater in 1964 than in 1965; data on the other chemical properties indicated that the oil had not undergone appreciable alteration prior to being analyzed. The reasons for the above variations could not be determined, since several variables were operating simultaneously. Vol. 4, No. 4. Author index of publications and addresses — 1966.

Shrimp-behavior studies underly- ing the development of the electric shrimp- trawl system. By Edward F. Klima. Decem- ber 1968, pp. 165-181, 16 figs., 9 tables. ABSTRACT Observation of how shrimp react to different amounts of electrical energy and repetition rates of pulsating direct current in the laboratory and the field provided information on the electric char- acteristics needed for an effective electric shrimp trawl. The laboratory studies showed the electric thresh- old voltage of shrimp oriented at different positions to the electrodes and the effect of different voltages on the shrimp's responses. Threshold voltages were affected by the animal's position relative to the elec- tric field, and the shrimp's reaction increased with an increase in voltage. The field studies provided information on the elec- trical output needed to force burrowed shrimp out of the substrate. Capacitor-discharge pulses of 4 per second with a potential of 3.0 volts or more across 100 millimeters parallel to the electric field were best for forcing shrimp out of the types of bottom on some of the commercial shrimping grounds in the Eastern Gulf of Mexico.

ABSTRACT In the Eastern Tropical Pacific Ocean, about 50 percent of the purse seine sets for tuna are unsuc- cessful, owing mostly to the fish's escaping the net during setting and pursing operations. Described here is the design of a proposed purse seine that will largely retain the desirable features of the presently used seine but that will sink faster and use the webbing with greater economy. In comparative tests with scale models (1:25), the model built ac- cording to the proposed design sank nearly three times as fast as did the model of the presently used Fishery Leaflet 606.

ABSTRACT Salmon traps, now nearly extinct, are the most efficient fishing gear ever developed for the capture and impoundment of salmon. The first salmon trap was built in Cook Inlet about 1885, but floating traps were not introduced until after 1890. The number of traps varied annually until the State Legislature abolished them in 1959. In 1967, only three traps were operated in Alaska in a Federal Fishing Reserve set aside by President Woodrow Wilson for the Metlakatla Indians on Annette Island. A floating salmon trap consists of a lead, outer and inner hearts, pot, and two spillers. Meth- ods of hanging, setting, and brailing a trap are given. 612. Published in 1967. 613.

Water quality of streams tributary to Lakes Superior and Michigan, by Jerome W. Zimmerman. January 1968, iii + 41 pp., 2 figs., 11 tables, 1 app. ABSTRACT Water quality of streams tributary to Lakes Su- perior and Michigan was analyzed for 142 stations on 99 streams tributary to Lake Superior and 83 stations on 56 streams tributary to Lake Michigan during 1962-65. Concentrations of aluminum, copper, and iron were not affected greatly by flow or season. Mag- nesium, calcium, chlorides, total alkalinity, total hardness, and conductivity varied with the flow, tem- perature, and season; the lowest values were dur- ing the spring runoff and heavy rains, and the high- est were during low water in late summer and the colder periods of winter. Concentrations of nitrate, silica, and sulfates were lowest in the spring and summer. Concentrations of tanninlike and lignin- like compounds were highest during the spring run- off and other high-water periods, and were lowest during freezeup when surface runoff was minimal. The pH values were highest from June to Sep- tember and lowest during the spring runoff. Phenol- phthalein alkalinity was detected primarily in the summer and coincided occasionally with low flows just before the spring thaw. Total hardness usually was lower in streams tributary to Lake Superior than in streams tributary to Lake Michigan. The total hardness was higher in the streams in Wis- consin than in the streams in Michigan along the west shore of Lake Michigan. It was lowest in the northernmost streams. The water quality of the streams in an area was related to the geological characteristics of the land. 560. Published in 1967. 561. Diel and seasonal occurrence of pink shrimp, Penaeus duorarum Burkenroad, in two divergent habitats of Tampa Bay, Florida, by Carl H. Saloman. January 1968, iii + 6pp., 4 figs., 6 tables. ABSTRACT Pink shrimp, Penaeus duorarum, were sampled for 17 months in two divergent habitats in Tampa Bay, Fla. Information was obtained on size and sex of the shrimp, water temperature, salinity, light transmission, and activity in relation to moon phase. Catches were larger during darkness and rose as temperature decreased from about 30° C to 14° C. Larger shrimp were caught in darkness than in day- light throughout the period. Larger shrimp were also caught at the station having lowest salinity and incidence of transmitted light. In dark phases of the moon greater numbers of shrimp were caught than during light phases. The size of shrimp reached a peak in April and May after an average increase in length of about 1 mm carapace length per month. Female shrimp were larger than males in all samples except two. 562. Seasonal and areal distribution of zoo- plankton in coastal waters of the Gulf of Maine, 1965 and 1966, by Kenneth Sherman. March 1968, iii + 11 pp., 6 figs., 6 tables. ABSTRACT A description is given of the abundance, compo- sition, and seasonal variations in distribution of zooplankton. Eleven major taxa were represented in the samples. Six were holoplanktonic, and five were meroplanktonic. Copepods were the dominant zooplankters during all seasons in both years. Zoo- plankton volumes in both years followed similar areal trends. Mean annual volumes were highest in the western area (Cape Ann to Cape Elizabeth), moderate in the central area (Cape Elizabeth to Mt. Desert Island), and low in the eastern sector (Mt. Desert Island to Machias Bay). Zooplankton volumes were generally lower in 1966 than in 1965. Areal and annual variations in the abundance of zooplankters are discussed in relation to hydro- graphy. 563. Bibliography of oyster parasites and di- seases, by Carl J. Sindermann. April 1968, 13 pp. ABSTRACT The bibliography is oriented toward the diseases that affect oysters and is not concerned with human diseases that may be transmitted by raw shellfish. References to parasites and diseases of pearl oysters (Pteriidae) have been included, even though such bivalves are not true oysters (Ostreidae). Refer- ences to mortalities of oysters have been included only if a pathogen was associated or suspected. Particular emphasis has been placed on disease states resulting from an infectious agent or para- site invasion. 564. Description and evaluation of methods for determining incident solar radiation, subma- rine daylight, chlorophyll a, and primary pro- duction — Used by Scripps Tuna Oceanogra- phy Research Program in the eastern tropical Pacific, by Robert W. Holmes . December 1968, iii + 31 pp., 5 figs., 15 tables. ABSTRACT A detailed account and evaluation are presented for certain methods used by the STOR (Scripps Tuna Oceanography Research) Program. This de- scription should assist readers and users of the STOR data and be of general interest to workers in the field. An Eppley 10-junction 180° pyranometer was used in conjunction with a Speedomax recorder for the measurement of incident solar radiation. Daily incident radiation was obtained by integration of the daily record with a polar planimeter. Errors due to integration and failure of the gimbals to stabilize the pyranometer completely are estimated to be ± 1 percent and ± 5 percent, respectively. A comparison between observed daily radiation and computed radiation from four standard climatologi- cal equations revealed the inaccuracy of using in- direct methods for daily totals. The deck and submarine irradiance meters were equipped with cosine collectors; their construction, calibration, and operation are described. A blue- green Wratten filter (No. 45) was routinely used with both detectors. The relative spectral sensitiv- ity in air and Jerlov ocean water type I was cal- culated. In air, the maximum transmittance was at 490 m/i and the half-band width was roughly 63 m/x. At 100-m depth in type I water, this value shifted to 475 m/z with a 50 m/i band width. By assuming the universal validity of the Jerlov sea- water transmission curves, it was possible to obtain estimates of total visible downwelling irradiance at depth from a single attenuation coefficient measure- ment. Under ideal conditions and with no depth measurement error, a coefficient of variation of ± 10.5 percent was obtained for the attenuation co- efficient. This error increased appreciably when vessel motion and errors of depth measurement oc- curred. Chlorophyll a measurements were obtained by spectrophotometric method with acetone extracts of membrane-filtered water samples. Corrections for blank values at 750 m/x were applied, and con- centrations computed with the equations of Richards with Thompson. The coefficient of variation for surface samples varied between 14 and 27 percent and increased with depth. Primary production was measured with C14; the details of the methodology and standardization are given. Because a number of different incubation techniques were used (i.e., in situ, deck incubator, trailing bottle, and laboratory incubator) , an at- tempt was made to compare these procedures with the in situ method. All of the methods yielded results which were correlated with those obtained by the in situ method. Thus unbiased estimates of in situ production may be obtained from the different incubation techniques. 565. Passage conditions and counts of fish at the Snake Island fishway, Little Falls Dam, Potomac River, Md., 1960-63, by Paul R. Nichols. February 1968, iii + 14 pp., 7 figs., 5 tables. ABSTRACT Resident fish such as sucker, carp, channel cat- fish, bluegill, and black crappie travelled through the fishway, but apparently no anadromous fish ascended the river far enough to reach the fishway. It is possible that: (1) the runs of anadromous fish are now at such a low level that the spawning area above Little Falls is not needed as in former years; (2) the stocks with the instinct to move above Little Falls which were blocked from their natural spawning ground when the Little Falls Dam was rebuilt in 1949 have since disappeared; and (3) the rapids between Chain Bridge and the fish- way may deter the upstream progress of migrating fish. Success in reestablishing runs of anadromous fish above Little Falls may require the planting of fertilized eggs and adult fish in the upper river and the construction of fish-passage facilities at the rapids above Chain Bridge. Successful hatch- ing of shad eggs and the collection of young shad above Little Falls indicate that the river is suitable for the restoration of this species. 566. Horizontal and vertical distribution of juvenile salmonids in upper Mayfield Reser- voir, Washington, by Jim Ross Smith, John R. Pugh, and Gerald E. Monan. April 1968, iii + 11 pp., 6 figs., 6 tables. ABSTRACT The proposed installation of a fish collecting de- vice in the upper end of Mossyrock Reservoir, soon to be created on the Cowlitz River in southwestern Washington, prompted this study to determine the horizontal and vertical distribution of juvenile salmonids in such an environment. A section of the upper end of Mayfield Reservoir, an existing body of water on the Cowlitz River, was systemat- ically sampled with gill nets and a trawl from April 1964 to June 1965. Eighty-seven percent of the 11,467 salmonids captured were taken in the upper 7.3 m of water, which constituted 52.8 percent of the total sampling area. If the distribution of fish in upper Mossyrock Reservoir is similar to the distribution in Mayfield Reservoir, a collecting device running from shore to shore, extending to a depth of 7.3 m, and designed to collect fish approaching from both the upstream and the downstream sides should collect over 80 percent of all migrating salmonids. 567. Setting and first season survival of the American oyster, Crassostrea virginica, near Oxford, Maryland, 1961-62, by J. R. Webster and W. N. Shaw. July 1968, iii + 6 pp., 2 figs., 4 tables. 10 ABSTRACT The setting of oysters in Broad Creek and Tred Avon River, on the eastern shore of Chesapeake Bay, was monitored during 1961 and 1962. Setting was substantially greater both years in Broad Creek, and the highest number of spat were found on shells suspended from 0.3 to 9 meters below the surface. Three times more spat were caught on shells in bags than on shells broadcast on the bottom. In Tred Avon River setting was very light in 1961 and light in 1962, except during the week of 30 July to 6 August. In Broad Creek setting was heaviest during the week of 17 to 24 July 1961 and during each week from 25 June to 13 August 1962. First-season survival rates were 1 to 27 percent. There was some indication, especially in Broad Creek during 1962, that the greater the setting rates the lower the first-season survival rates. 568. The Japanese Atlantic longline fishery, 1964, and the status of the yellowfin tuna stocks, by John P. Wise. August 1968, 5 pp., 1 fig., 5 tables. ABSTRACT The Japanese Atlantic longline fishery increased in 1964 to nearly 85 million hooks. Catches of yel- lowfin tuna decreased slightly, while catches of al- bacore increased markedly. Even though fishing has decreased since 1964, the effort is still greater than necessary for optimum yield in numbers of yellowfin tuna. 569. Oyster mortalities, with particular refer- ence to Chesapeake Bay and the Atlantic coast, of North America, by Carl J. Sindermann. July 1968, iii + 10 pp., 7 figs. ABSTRACT A number of recent mass mortalities of oysters of the Middle Atlantic States and elsewhere in the world have been attributed to the effects of disease. Oyster production in Delaware Bay and lower Chesapeake Bay has been seriously reduced during the past decade by an epizootic of a protozoan path- ogen, Minchinia nelsoni. Other recent disease-as- sociated mortalities of oysters have occurred in the Gulf of Saint Lawrence and the Gulf of Mexico. Man may have aided spread of diseases by transfers and overcrowding of beds. Reduction of this threat to oyster production could be effected by quaran- tines, development of disease-resistant strains of oysters, and use of environmental barriers (such as low salinity) to the pathogens involved. 570. Fishes taken during shrimp trawling along the south Atlantic coast of the United States, 1931-35, by William W. Anderson. July 1968, iv + 60 pp., 9 figs., 13 tables. ABSTRACT Fish of numerous families and species are taken with shrimp on the shrimping grounds. Records of the fish taken during a study of the white shrimp by the U.S. Bureau of Fisheries, are provided. These records cover the coast from Cape Romain, S.C., to Cape Kennedy, Fla., and are organized under four basic areas : South Carolina Outside, Georgia Out- side, Georgia Inside, and Florida Outside. The en- tire region is treated also as a unit. Yearly and monthly average numbers of fish taken per hour of trawling and percentages of the catch are provided for all species for the region and for the several basic areas. Seasonal variation in the numbers of fish on the shrimp fishing grounds is large; numbers are low- est during the late winter and spring, build up rap- idly in the summer and early fall, and are highest in the late fall and early winter. The croaker family (Sciaenidae) was the most abundant and important found on the shrimp fish- ing grounds. Croakers were captured in greater numbers than all other families of fish combined in every month of the year. Four families of fish — The Sciaenidae (croakers), Carangidae (jacks), Ariidae (sea catfish), and Bothidae (flounders) — were taken in greatest num- bers per hour of trawling and together contributed almost 87 percent of the yearly average catch in the region. Seven species of fish — Stellifer lanceolatus (star drum), Micropagon undulatus (Atlantic croaker), Leiostomas xanthurus (spot), Menticirrhus spp. (king whiting), Chloroscombrus chrysuriis (bump- er), Cyyioscion regalis (gray seatrout) , and Etropus crossotus (fringed flounder) — each contributed 3 percent or more of the yearly average catch for the region, and together represented over 76 percent of the yearly average catch in the region. 571. Spawning areas and abundance of chinook salmon (Oncorhynchus tshmvytscha) in the Columbia River Basin — past and present, by Leonard A. Fulton. October 1968, iii + 26 pp., 5 figs., 8 tables. ABSTRACT Chinook salmon, the most abundant species of salmon in the Columbia Basin, formerly spawned in nearly all tributaries of the Columbia River and in many areas of the main river. Over the past 60 years, the construction of dams has inundated, im- peded, or blocked access to spawning areas. Despite these heavy losses, large areas of spawn- ing grounds in the middle and lower portions of the drainage are still available to chinook salmon. Stream improvements by State and Federal fishery agencies have rehabilitated some areas and have brought others into production for the first time. Important spawning areas are listed and charted in this report according to their past use (before 1965) and present use (1966). Estimates of recent spawning populations in major tributaries and in segments of the main stem are also given. Former 11 and present levels of abundance are listed according to three major runs — spring, summer, and fall. 572. Effects of lamprey larvicides on inverte- brates in streams, by Richard L. Torblaa. August 1968, iii + 13 pp., 2 figs., 11 tables. ABSTRACT The study was conducted on five streams tribu- tary to Lake Superior and four tributary to Lake Michigan. Samples of the bottom fauna before and after chemical treatment revealed that most groups of aquatic organisms were not adversely affected by exposure to larvicides. The total number of in- vertebrates was smaller 1 week after treatment than before treatment, increased somewhat by 6 weeks after treatment, and had returned to pretreatment levels 1 year after treatment. Aquatic insects were affected less than other organisms, and invertebrates were more severely affected and recovered more slowly in areas of sand and detritus than in riffle areas. 573. Physical, chemical, and biological ocean- ography of the entrance to the Gulf of Cali- fornia, spring of 1960, by Raymond C. Grif- fiths. December 1968, iii + 47 pp., 40 figs., 1 table. ABSTRACT The whole area at the entrance to the Gulf of California and off southwestern Lower California in the spring of 1960 was underlain by Intermediate Water (marked by a salinity minimum of about 34.5 ppt at about 800 m) and, above that, by Subtropical Subsurface Water (marked by a sa- linity maximum of 34.80 ppt at about 200 m). Above these waters were: to the northwest, Cal- ifornia Current Surface Water (marked by a shal- low salinity minimum of about 34.10 ppt at about 100 m) ; to the northeast, Gulf Surface Water (marked by high surface salinities that obscure the maximum of the Subtropical Subsurface Water) ; and, to the south, Subtropical Surface Water (marked by intermediate salinities and high tem- peratures). The most important oceanographic feature of the area was a strong front between California Current and Gulf Surface Waters. At Cape San Lucas this front was roughly vertical, but to the south and west it became more sinuous and much weaker and was formed more and more by California and Sub- tropical Surface Waters. At the Cape the stronger flow of the California Current Water seemed to hold back the Gulf outflow at the surface, and to the south of the Cape it penetrated Gulf Surface Water at depths between 50 and 100 m, spreading horizontally or affecting in some way the entire Gulf entrance, often in a complicated manner. The vertical front at Cape San Lucas thus became a horizontal one offshore at depth. The frontal sys- tem was very clearly shown in the distributions of temperature and salinity in the upper 100 m, but only between 50 and 100 m in the oxygen distribu- tion. The Subtropical Subsurface Water was in the ex- tensive oxygen minimum of the eastern Pacific, and the oxygen content of the surface waters was af- fected by upwelling and probably by phytoplankton activity. The second important feature of the area was upwelling. Distributions of temperature, salinity, and oxygen showed it to be strong off western Lower California and weaker off Cape Corrientes and other parts of the eastern side of the Gulf entrance. The water upwelled off Lower California was ini- tially low in oxygen content, but this content in- creased as the water moved south. The distribu- tions of temperature and, particularly, salinity showed this transport. The standing crop of zoo- plankton was generally highest in the areas in which upwelled water occurred. 574. Some operational aspects of the Hawaiian live-bait fishery for skipjack tuna {Katsuivon- us pelamis) , by Vernon E. Brock and Richard N. Uchida. September 1968, iii + 9 pp., 1 fig., 5 tables. ABSTRACT An analysis of detailed operating records of two Hawaiian skipjack tuna vessels during 1952 and 1953 indicated consistent patterns of time utiliza- tion and activities that probably were representa- tive for the Hawaiian skipjack tuna fleet during these 2 years. Availability of skipjack tuna appears to be lowest during the winter; hence, the vessels are drydocked and repaired then. The pattern of fishing was marked by a period of bait collection lasting a day or more, followed by a period of fishing that lasted from 1 to 5 days, but generally was 3 days or less. Baitfish mortality rates were so high that it was difficult to maintain a large quantity of live bait, or to fish successfully for more than 3 days. The design of the skipjack tuna vessels and their operating procedure reflected these constraints in the use of bait. Long-range vessels with refriger- ation, possibly able to fish more efficiently during the winter, would be impractical without the devel- opment of methods to reduce baitfish mortalities. A fishery for live bait, independent of the tuna fish- ing vessels, would require the same techniques to be successful. Much of the time at sea was spent in searching for fish rather than in fishing. A reduction in time spent searching would reduce the loss of baitfishes in the baitwells and increase the catch of skipjack tuna for baitfish used. Hence, knowledge of areas where skipjack tuna are concentrated would be of substantial value to the fishery. 575. Length relations of some marine fishes 12 from coastal Georgia, by Sherrell C. Jorgen- son and Grant L. Miller. November 1968, iii + 16 pp., 3 tables.

Oceanographic surveys of Traitors Cove Revillagigedo Island, Alaska, by Douglas R. McLain. December 1968, iii + 15 pp., 15 figs., 2 tables. ABSTRACT Traitors Cove is a small fiordlike estuary in south- eastern Alaska. It is divided into two basins by a narrow constriction, where a reversing tidal falls forms. Four oceanographic surveys of the estuary between 1963 and 1965 showed that this tidal falls creates a region of strong turbulence and destroys the stratification of the water near it. Surface cur- rents in the estuary are predominantly seaward on ebb tide and toward the head of the estuary on flood tide. 577-578. Published in 1969. 579. A list of the marine mammals of the world, by Dale W. Rice and Victor B. Scheffer.
