 (Pisces, Scombridae) in the Northwestern 

 Gulf of Guinea and Off Sierra Leone, Geronitno 

 Cruise 5, 10 February to 19 April 1965. United 

 States Department of the Interior, Bureau of 

 Commercial Fisheries. By W. J. Richards, 

 David C. Simmons. Ann Jensen, and Walter 

 C. Mann. April 1970, 24 pp. on 1 microfiche. 



ABSTRACT 

 The number of tuna and frigate mackerel larvae 

 are given by size class, and associated station 

 data are listed.

 River System, Alaska. United States De- 

 partment of the Interior. Bureau of Commer- 

 cial Fisheries. Duane E. Phinney. January 

 1970, 147 pp. on 3 microfiche. 



ABSTRACT 

 All known information about the sockeye salmon 

 runs and the spawning grounds of the Chignik 

 River System, Alaska, is cataloged in this report. 

 The system, which is composed of two lakes, Chignik 

 and Black, supports the largest run of sockeye 

 salmon on the south side of the Alaska Peninsula. 

 The catalog lists for each spawning stream or beach 

 the name, location, physical description, description 

 of the sockeye salmon runs, and a chronological 

 listing of the spawning ground surveys. 



42. Temperature, Salinity, and Transparency 

 Observations, Coastal Gulf of Maine. 1962- 

 65. United States Department of the Interior, 

 Bureau of Commercial Fisheries. By Joseph 

 J. Graham. January 1970, 44 pp. on 1 micro- 

 fiche. 



ABSTRACT 

 The observations are plotted for 11 cruises. 

 Temperature usually increased and salinity de- 

 creased from east to west along the coast. These 

 trends were complicated vertically by less tidal 

 mixing and larger river discharges in the west, 

 causing a more pronounced vertical stratification 

 there than in the east. Transparency usually in- 

 creased from inshore to offshore, and at times the 

 distribution of isolines of transparency agreed 

 closely with those of temperature. 



43. Temperature, Dissolved Oxygen, Total Alka- 

 linity, and Biochemical Oxygen Demand in 

 the Columbia River Estuary, 1966-67. United 

 States Department of the Interior. Bureau of 

 Commercial Fisheries. By Carl W. Sims, and 

 Carl J. Cederholm. January 1970, 34 pp. on 

 1 microfiche. 



ABSTRACT 

 These data collected at 19 locations in the Co- 



lumbia River estuary are presented as a reference 

 for researchers in fisheries or in water quality. 



44. Stream Catalog of Southeastern Alaska 

 Regulatory Districts Nos. 10 and 11. United 

 States Department of the Interior, Bureau of 

 Commercial Fisheries. By E. J. Huizer, T. 

 H. Richardson, and Norman Johnston. Febru- 

 ary 1970, 268 pp. on 4 microfiche. 



ABSTRACT 

 Information about part of Southeastern Alaska 

 salmon streams is cataloged from the voluminous 

 records of the Alaska Department of Fish and Game; 

 the Alaska Salmon Industry; the Fisheries Re- 

 search Institute of the University of Washington; 

 the U.S. Fish and Wildlife Service, Bureau of Com- 

 mercial Fisheries; and other agencies. Stream des- 

 criptions, maps, and historical records of salmon 

 escapement data are compiled for 71 salmon streams 

 in Southeastern Alaska Regulatory Districts 10 

 and 11. Each stream is located geogi-aphically by 

 latitude and longitude and by orientation to prom- 

 inent landmasses. A standard numbering system, 

 number designations formerly in use, and common 

 names of streams are listed. Physical descriptions 

 are presented for the intertidal zone and the up- 

 stream area of each stream. Available records of 

 weather, water temperatures, and information 

 useful to ground and aerial stream surveyors are 

 presented in brief form. The species of salmon 

 using the spawning grounds and estimates of the 

 escapements each year for many years are given.
