FOODS OF JUVENILE SOCKEYE 

 SALMON, ONCORHYNCHUS NERKA, IN 

 THE INSHORE COASTAL WATERS OF 



BRISTOL BAY, ALASKA, 1966-67 



For most living organisms the early portion of life 

 is most critical in determining survival. Anad- 

 romous fishes such as Pacific salmon have two 

 critical periods during early life — development 

 and growth in fresh water and subsequent adap- 

 tation to a marine environment. The food of 

 juvenile salmon during the first few months of 

 marine life influences growth and condition, 

 which in turn probably influences parasitism, 

 predation, and other factors which ultimately 

 determine marine survival. 



Although the sockeye salmon, Oncorhynchus 

 nerka (Walbaum), is one of the most valuable 

 commercial fishes in Alaska and has been the ob- 

 ject of extensive research, little is knovm of its 

 early life in the sea. Straty (1974) and Straty and 

 Jaenicke^ have made the only comprehensive 

 study of early marine life of the sockeye salmon 

 in Bristol Bay, historically the largest sockeye 

 fishery in the North Pacific. Documented studies 

 of sockeye salmon food habits during this period 

 of life are generally limited to brief accounts of 

 Soviet research in Kamchatka waters (Synkova 

 1951), a study in British Columbia (Manzer 

 1969), examination of a few specimens from Aleu- 

 tian and Kodiak waters (Chamberlain 1907), and 

 45 specimens taken off Cape Seniavin in lower
