Ecology of Spirinchus thaleichthys
 
Main Ref. Scott, W.B. and E.J. Crossman, 1973
Remarks Found close to shore, in bays and estuaries and ascends coastal streams to spawn (Ref. 5723). There are landlocked populations (Ref. 5723) but these do not reach as great a size as sea-run fish (Ref. 27547). Individuals found in brackish and salt water feed on small crustaceans (Ref. 1998).
