Monitoring of the blue crab fishery (Paralithodes platypus Brandt) in the throat of Shelikhov Bay in January 2018

Abstract

It is stated that January there is the most intensive blue crab fishing period in the Shelikhov Bay during the year. At the same time, the catch of males of commercial size per day was 13.474 tons or 7600 pcs. However, this value does not reflect the real possibility of catching per day, since it is limited to the possibility of raw material processing per day (15–16 tons). Information on the size-weight composition of catches and the biological state of crabs is given, as well as the species composition of the by-catch of other species of fish and invertebrates in trap fishing is analyzed.
