521. Bureau of Commercial Fisheries Sympo- 

 sium on Red Tide. By James E. Sykes. Sep- 

 tember 1965, 11 pp. 



ABSTRACT 

 In October 1964, the Bureau of Commercial Fish- 

 eries held a Red-Tide Symposium at St. Petersburg 

 Beach, Fla. Purposes were to review progress on 

 red-tide research in recent years, to exchange views 

 on the nature of current investigations, and to de- 

 termine where emphasis should be placed in further 

 studies. .Abstracts of presentations by 14 partici- 

 pating scientists are included in this report. Eleven 

 areas of red-tide research were cited as needing at- 

 tention in continuing studies.

ABSTRACT 

 The seventh year of pelagic research on the fur 

 seal {Callorhinus ursinus) , under the terms of the 

 Interim Convention of North Pacific Fur Seals was 

 carried out off California, Oregon, and Washington 

 from 7 April to 1 June, and in the Bering Sea from 

 4 July to 8 September 1964. Seals collected off Cal- 

 ifornia totaled 305 ; off Oregon, 10; off Washington, 

 28; and in the Bering Sea, 533. Fewer seals were 

 seen off California in April and May 1964 than dur- 

 ing similar research in January to March in 1958, 

 1959, and 1961 ; young females formed a larger pro- 

 portion of the collections in 1964 (21-30 percent) 

 than in previous years (10, 9, and 15 percent) ; 76 

 percent of the total males taken in all 4 years off 

 California were collected in 1964. Summer distri- 

 bution of seals in the Bering Sea was similar to that 

 in 1962 and 1963. Females, predominantly mature, 

 made up 91 percent of the Bering Sea collections. 

 The percentage of tagged seals in pelagic samples 

 increased progressively from 0.9 in 1958 to 4.9 in 

 1964. A seal tagged by the U.S.S.R. and recovered 

 by a U.S. vessel was collected on 28 -August about 

 60 miles northeast of St. Paul Island. The preg- 

 nancy rate (76.4 percent) was lower than in pre- 

 vious years because samples were taken off Califor- 

 nia during a period when a higher proportion of 

 nulliparous and nonpregnant females were present. 

 Gooseneck barnacles {Lepas sp.) and algae (Fc- 

 tocarpus sp.) growing on the guard hairs of seals 

 were more common in the spring of 1964 than in 

 winter collections of other years. Thirty-three food 

 species were identified in 876 stomachs in 1964. 

 Merluceius prodiictris was the major food off Cal- 

 ifornia, Oregon, and Washington. Squids, Clupea 



harengus pallasi, Theragra chalcogrammus, Bathyl- 

 agidae, and Mallotus villos7(S were the leading foods 

 in the Bering Sea.

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 

 Research Institute of the University of Washing- 

 ton; the U.S. Fi.sh and Wildlife Service, Bureau 

 of Commercial Fisheries; and other agencies. 

 Stream descriptions, maps, and historical records 

 of salmon escapement data are compiled for 130 

 salmon streams in Southeastern Alaska Regulatory 

 Districts Nos. 5, 6, 7, and 8. Each stream is lo- 

 cated geographically by latitude and longitude and 

 by orientation to prominent landmasses. A stan- 

 dard numbering system, number designations for- 

 merly in use, and common names of each stream are 

 listed. Physical descriptions are presented for the 

 intertidal zone and the upstream area of each 

 stream. Available records of weather, water tem- 

 peratures, and information useful to ground and 

 aerial stream surveyors are presented in brief form. 

 The species of salmon utilizing the spawning 

 grounds and estimates of the escapements each year 

 for many years are given.

 Information about part of Southeastern Alaska 

 salmon streams is cataloged from the voluminous 

 records of the Alaska Department of Fish and

 Research Institute of the University of Washington; 

 the U.S. Fish and Wildlife Ser^dce, Bureau of Com-

 scriptions, maps, and historical records of salmon 

 escapement data are compiled for 53 salmon streams 

 in Southeastern Alaska Regulatory District No. 9. 

 Each stream is located geographically by latitude 

 and longitude and by orientation to prominent land- 

 masses. A standard numbering system, number 

 designations formerly in use, and common names 

 of each stream are listed. Physical descriptions 

 are presented for the intertidal zone and the up-
