 States, 1969-70. By U.S. Department of the

ABSTRACT 

 Seventy-eight fishery cooperatives in 15 States 

 and Puerto Rico are listed. Also included in most 

 instances are the name of one of the officers of each 

 co-op, the number of members, the number of boats 

 owned by members, the type of cooperative, and 

 the major species offish and shellfish caught.

ABSTRACT 

 Fishery Bulletins are technical reports on scien- 

 tific investigations of fishery biology. The Bulletin 

 of the United States Fish Commission was begun 

 in 1881; it became the Bulletin of the Bureau of 

 Fisheries in 1904 and the Fisheiy Bulletin of the 

 Fish and Wildlife Service in 1941. Separates were 

 issued as documents through volume 46; the last 

 document was No. 1103. Beginning with volume 

 47 in 1931 and continuing through volume 62 in 

 1963, each separate appeared as a numbered Bul- 

 letin. A new system began in 1963 with volume 63, 

 in which papers are bound together in a single 

 number of the Bulletin. Available Bulletins are 

 distrubuted free to libraries and to a limited 

 number of universities and other scientific co- 

 operators. A listing of all Bulletins in volumes 47 

 through 6.5 is distributed free by the Division of 

 Publications, Bureau of Commercial Fisheries, 1801 

 N. Moore St., Arlington, VA. 22209. If you need

630. A Brief History of Commercial Fishing in 

 Lake Erie. By Vernon C. Applegate and 

 Harry D. Van Meter. April 1970, iii + 28 pp., 

 8 figs., 16 photos, 1 app. table. 



ABSTRACT 

 Salient features of the development of the industry 

 from about 1815 to 1968, changes in fishing gears 

 and methods, changes in the kinds and abundance 

 of fishes caught, and the attendant effects of disap- 

 pearing species on the stability of the fishery are 

 described. The history and present status of the 

 walleye, yellow perch, and eight other fishes, still 

 taken in commercial quantities, are presented in 

 more detail and are considered in the context of 

 their effect on the current moribund state of the 

 U.S. fishery. Past and present contributions of 

 Lake Erie's tributaries and northerly connecting 

 waters to the fishery are outlined briefly. The "out- 

 look" for the fishery under present conditions of 

 selective overfishing for high-value species, ex- 

 cessive pollution, ineffective and uncoordinated 

 regulation, and antiquated methods of handling, 

 processing, and marketing fish are discussed, and 

 possible solutions to these problems are suggested. 



631. Alaska's Fishery Resources — The Shrimps. 

 By Louis Barr. January 1970, iii + 10 pp., 

 7 figs., 1 table. 



ABSTRACT 



Shrimp fishing began in Alaska over 50 years 

 ago. Recently the annual domestic catch has been 

 as high as 40 million pounds. Japanese and Soviet 

 Union fishermen operating in Alaska waters have 

 caught as much as 70 million pounds annually in 

 recent years. 



The five commercially important shrimp of Alaska 

 belong to the family Pandalidae; the most important 

 is the pink shrimp, P<nid(iliis borealis. The com- 

 plicated life histories of these shrimp are all similar. 

 The shrimp develop first as males and after several 

 years transform to females, which they remain for 

 the rest of their lives. 



United States fishermen use otter trawls, beam 

 trawls, and pots, and deliver their catch to ports 

 in Alaska; foreign fishermen use larger otter trawls 

 and process the catch at sea. 



The Alaska Department of Fish and Game and 

 the Bureau of Commercial Fisheries are studying 

 shrimp. They are sampling the commercial catch, 

 trying to improve the product, and conducting ex- 

 ploratory fishing and biological research. 



632. Alaska's Fishery Resources — The Chum 

 Salmon. By Theodore R. Merrell, Jr. June 

 1970, iii -I- 7 pp., 6 figs., 2 tables. 



ABSTRACT 

 The chum salmon, Oticorhy)ichiis ketit. is the 

 most widely distributed and second most abundant 

 of the five Pacific salmon. It is one of Alaska's 

 valuable fishery resources. Chum salmon spawn in 

 late summer and fall — some in small streams near 

 the ocean and others in large rivers in which they 

 travel as far as 1,500 miles from the ocean. The 

 young hatch in midwinter but stay in the stream 

 gravel until spring, when they emerge and migrate 

 to sea. They spend 2 to 4 years in the sea and weigh
