Abstract
The purpose of this work is to assess the state of the red king crab population, as well as to collect related information about other types of invertebrates found in the study area. Materials and methods: a total of 114 trawl stations were made onboard the R/V Professor Boyko at depths from 42 to 185 m, which made it possible to cover a water area of 46.6 thousand square meters. km. Calculations of population density and biomass of organisms are given. Also, for the densest concentrations of invertebrates, the temperature and distribution depths were determined. Results of the study: the basis of trawl catches on the shelf of the south-eastern part of the Barents Sea was 8 species of commercial and by-catch of 34 species of non-commercial invertebrates, assigned to 6 groups of different taxa. The paper provides information on the biological state, distribution and biomass. The practical significance lies in the provision of annual forecasting materials on the total allowable catches of bottom commercial aquatic species for the Barents Sea.
