Influence of Water Salinity on the Physiological Status and Distribution of Juvenile Chum Salmon in the Estuary of the Ola River of the Northeast Coast of the Okhotsk Sea

摘要

Identification of individual fishes by their specific features, natural or artificial markers, is the basis for differentiating between individual populations and fish groups in mixed stocks. The significant number of thermally marked fish released from the Ola Salmon Hatchery gives us an opportunity to conduct a large-scale research of various salmon stocks on the basis of their identification at any stage of their life cycle.
