Juveniles of pink and chum salmon in the southern Okhotsk Sea in their late marine stage (August-October 2012). Distribution, feeding, patterns of growth
Ontogeny of one generation of pink and chum salmons is described for the period after their juveniles redistribution from coastal waters to deep-water areas in the central and southern Okhotsk Sea in August-November, 2012. The juveniles fed very intensively in August when their diet had about 85 % o...
