Investigation of Pacific squid fishing processes in the Russian waters of the Sea of Japan

The development of the Pacific squid fishery in the economic zone of the Russian Federation of the Sea of Japan was studied. The accumulations of squid were studied and shown both in the daytime and at night, which determine the technique and technology of fishing for the Pacific squid with trawls. Dense aggregations of squid form in the daytime over highlands, catches per haul can be up to 45 tons, and at night they are distributed in the water column, such behavior is typical for other pelagic objects, such as mackerel and sardines of iwasi. Warming of the surface waters of the Sea of Japan in the domestic economic zone was revealed, which contributes to the development of the Pacific squid trawl fishery.
