310. Japanese, Soviet, and South Korean fish- 

 eries off Alaska. Development and history 

 throug-h 1966. By Philip E. Chitwood. Jan- 

 uary 1969, 34 pp., 19 figs., 8 tables. 



ABSTRACT 



The history of fisheries off Alaska by a nation 

 from across the Pacific Ocean dates back to 1930. 

 In that year Japan dispatched a king crab expe- 

 dition into the eastern Bering Sea. Japanese ex- 

 ploitation of the eastern Bering Sea fishery resources 

 was expanded in 1933 when a groundfish fishery was 

 initialed. By 1941, Japan's fisheries in the eastern 

 Bering Sea had been halted because the Imperial 

 Navy had requisitioned most of Japan's vessels for 

 use in World War II. 



In 1952, after a lapse of 11 years, Japanese fishing 

 off .\laska resumed. In that year the Japanese be- 

 gan fishing for salmon along the western Aleutian 

 Islands. In 1953, they resumed their prewar fish- 

 eries in the eastern Bering Sea. 



The Japanese fleets off Alaska were joined in 1959 

 by U.S.S.R. fleets, which began fishing flounder and 

 king crab in the eastern Bering Sea and whaling 

 along the Aleutian Islands. 



During the early 1960's, both the Japanese and 

 the Soviets accelerated their exploitation of the fish- 

 ery resources off Alaska, working new grounds and 

 taking additional species. By the close of 1966, 

 fisheries of these two nations engulfed nearly all 

 the 550,000 square nautical miles of the Continental 

 Shelf off Alaska. Their fleets ranged from Dixon 

 Entrance in the south and east, to beyond Attu 

 Island in the west, and into the Arctic Ocean in the 

 north. Also in 1966, another Asian nation, South 

 Korea, made preparations to enter the fisheries oflf 

 Alaska. 



311. Billfishes of the Central Pacific Ocean. 

 By Donald W. Strasburg. April 1969, 11 pp., 

 7 figs. 



ABSTRACT 

 The billfishes are found in all warm seas. In the 

 central Pacific, the striped and blue marlins are 

 common or abundant; the black marlin is uncom- 

 mon; the Pacific sailfish, broadbill swordfish, and 

 shortbill spearfish are rarely caught. These fishes 

 feed broadly on fish, squid, crustaceans, and other 

 foods available on the high seas. In commercial 

 catches of blue marlin in Hawaii, males and females 

 appear in about equal numbers; but on a short- 

 term basis, one sex can predominate. During the 

 Hawaiian International Billfish Tournaments, which 

 are held during the summer, more males are usually 

 caught than females. In the commercial catch, 

 the heaviest blue marlin (300-500 pounds) were 

 taken in the spring, the lightest in the summer. 

 Striped marlin show two peaks of abundance 

 through part of the year. Blue marlin are most 

 abundant in the summer. Striped marlin tend to 



occur in large numbers just when the blue marlin 

 are least abundant. The longest migration recorded 

 in the central Pacific was 3,000 miles, by a striped 

 marlin that was tagged off Baja California, Mexico, 

 later caught near the Hawaiian Islands.

 eries Biological Laboratory, St. Petersburg 

 Beach, Florida, Fiscal Year 1968. By James 

 E. Sykes. May 1969, 2.5 pp., 19 figs., 8 tables. 



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 estuarine 

 fishery resources. The report describes current 

 research on projects in the Estuarine, Red-Tide, 

 and Industrial Schoolfishes Programs. The projects 

 include studies of sediments and organisms in bay 

 bottoms, plankton crops and fishes residing in and 

 transferring between estuaries and the Gulf of Mex- 

 ico, toxicity of the red-tide organism, and exper- 

 imental rearing of pompano in an impounded lagoon. 

 A physical, hydrological, biological, and sedimento- 

 logical inventory of Florida estuaries is also in pro- 

 gress as part of a cooperative effort with the Na- 

 tional Oceanographic Data Center and the States 

 of Alabama, Mississippi, and Louisiana.
