Materials of studies of the brown king crab and other crab species in the operational monitoring of the fishery (Aniva Bay, December 2017)
Abstract
The materials of the research of crab fishery in the southwestern part of the Sea of Okhotsk in December 2017 were presented. During the operational monitoring of the fishery of the brown king crab (Paralithodes brevipes), other species of commercial crab encountered in by-catch were studied simultaneously: the red king crab (P. camtschaticus) and the korean horsehair crab (Erimacrus isenbeckii). Also, data were collected on a small the helmet or horse crab (Teimessus cheiragonus). The tools of the trap were Japanesetype cone traps, arranged in order. The species observed in the catch were counted according to the size-sex groups, and a random sample of crabs was taken from several traps to perform the biological analysis. To describe the relationship between the filling of limbs with muscle tissue in crabs and the protein content in the hemolymph, relevant data are collected. The results of the conducted studies indicate that in the Aniva Bay area the commercial part in populations of the brown king crab and the korean horsehair crab is in a satisfactory state, and the population of the red king crab is characterized by the beginning of the restoration of numbers.
