Temporal Changes in Physiological Condition of Juvenile Chum Salmon and Zooplankton Biomass in a Coastal Water of the Okhotsk Sea

摘要

Japanese chum salmon (Oncorhynchus keta) are distributed along the coastal waters of Hokkaido for several weeks before their offshore migrations. Their survivals in the initial coastal life may be influenced by various factors. The aim of our research is to evaluate effects of coastal water temperature and zooplankton biomass on the physiological condition of juvenile chum salmon in a coastal water along the Okhotsk Sea.
