Modern Dynamics and Perspectives of Crab Fishery in Russia

Abstract
In the Russian Far East, the maximum catches of commercial crabs (37%) are registered in the North Okhotsk Sea sub-zone. From 2001 to 2017, the total annual crab catches increased at a 40% level and reached 69000 t. In the Prymorie sub-zone, landings of snow crab increased considerably, while in the northern part of the Sea of Okhotsk, the same pattern was registered for golden king crab and triangle tanner crab. Snow crab catches’ increase and blue king crab catches’ decrease were registered in the western part of the Bering Sea. These changes are associated with high fishing pressure and climate change. In the Northern Basin, commercial crab fisheries of the Russian Federation are supported by two non-indigenous species, red king crab and snow crab. The geography of the red king crab local fishery demonstrated displacement of the fishery outside the 12-mile zone and distribution of main fishing areas from the west to the east. In the last years, the total catches reached 9000–10000 t for king crabs and 8000 t for snow crabs. Positive tendencies in stock parameters let scientists predict further increasing the total allowable catches for both crab species.
Supporting agencies: The study was funded by the Ministry of Science and Higher Education of the Russian Federation within the framework of the state-ordered research themes of MMBI RAS and SSC RAS.
