Abstract
The process of fishing for the Commander squid and its features related to the hydrology of the Sea of Japan are considered. The areas and time of fishing in the Russian zone have been determined. The periodicity of the approach of commercial aggregations of the Commander squid by months along the continental slopes from the south of Western Sakhalin to the north of the Tatar Strait and further along the coast of Primorye to the south was revealed. Studies of the processes of interaction between trawls and aggregations of squid showed a calm behavior of the squid when interacting with the trawl and the squid leaving at a low speed into the pelagial. This made it possible to determine the choice of the parameters of the net cloths in the front part of the trawls (mesh pitch 100 mm and 60 mm), the speed of trawling more than 3 knots, as well as the minimum vertical openings of bottom trawls of 10-12 m. A scheme for the operation of small vessels using a single-wire system is proposed.
