Abstract

The principal patterns of feeding of downstream-migrant and coastal young of the year of coho salmon are considered. The so-called potential downstream migrants and residents, which differ in size and feeding patterns, were distinguished among coastal fry. It is assumed that identification of particular coastal specimens to phenotypic groups of downstream migrants or nonmigrants of young of the year of coho salmon may be determined even in the daytime by such parameters as the body length, feeding intensity, and food spectrum.
