Fishery resources of commercial invertebrates of Russian Seas and it’s use during 2000–2020

Abstract

The purpose of the work is to describe the changes of resources of commercial invertebrates in Russia and to analyze its use over the mentioned period.The research methods consisted in summarizing information on the state of the resources of commercial invertebrates in the seas of Russia and analyzing of the data of fishing statistics for 2000–2020.Results of the study are a description of the changes that have occurred with the main stocks of commercial invertebrates in the seas of Russia and the features of fishery, with an assessment of the current state of stocks.Discussion. The number of stocks for fishery prediction increased during the first two decades of the XXI century due to finding of new commercial fishery subjects. At the same time, a number of invertebrate stock units have lost their commercial significance over the past two decades of the XXI century. Сhanges in the structure of the resources and fishery of commercial invertebrates happened. The structure of invertebrates resources of the Far Eastern Fisheries basin proved to be the most conservative, while the importance of new fishing subjects significantly increased in the Northern and Azov-Black Sea fisheries basins.The novelty of the work lies in the analysis of the state invertebrates resources in the seas of Russia and their fishery in 2000–2020.Conclusion. In general, the fishery resources of invertebrates in the Russian Seas were fairly stable during 2000 to 2020, and ensured an increase in catch due to more full use.
