Abstract
The purpose of the work is to study the features of specialized pollock fishing in the North Pacific Ocean.
Identification of ways to increase the selectivity of specialized pollock fishing.
Methods used: features of specialized pollock fishing in the North Pacific Ocean were investigated by analyzing regulatory documents governing fishing in Russia, the USA and Canada. The study of the selectivity of specialized pollock fishing and ways to increase it was carried out by analyzing the results of experimental work on the pollock fishing.
Novelty: materials were obtained on the selectivity of specialized pollock fishing by Russian fishermen. Methods are proposed to increase selectivity of specialized pollock fishery.
Result: non-compliance of trawl bag parameters with the requirements of fishing rules in the Far Eastern fishery basin for by-catch of fish of non-mental length was revealed.
Practical significance: the obtained materials made it possible to assert that for the extraction (catch) of pollock in the North Pacific Ocean, which meets the requirements of fishing rules in the Far Eastern Fisheries Basin, there are a number of ways: an increase in the mesh size in a trawl bag to 120 mm or more, use in a trawl bag and with the landing of “T90,” use in a trawl bag flexible selective devices.
