Kuril Islands of the Sea of Okhotsk and the western part of the Bering Sea are an area of natural feeding of Pacific
salmon, and the catch area of ones for food market. Food safety of products is an important task of aquaculture.
Сoncentrations of HCHs (α-, β-, γ-) and DDT and its metabolites (DDD and DDE) were determined in organs of
the pink (Oncorhynchus gorbuscha), chum (O. keta), chinook (O. tshawytscha), and sockeye (O. nerka), which
caught from the natural aquaculture region of Russia (near the Kuril Islands (the northern-western part of the
Pacific Ocean), the Sea of Okhotsk and the Bering Sea). The average total concentration of OCPs in organs of salmon
from Western Pacific is lower than that in salmon from the North Pacific American coast and the Atlantic
Ocean. The region can be used to grow smolts, which will be later released into the ocean.
