The raw material base of fisheries and its use in the Russian waters of the Bering Sea. Message 2. Interannual dynamics of the projected and actual catch of aquatic biological resources at the present stage and in historical perspective

Based on many years of field data from the early 2000s. the inter-annual dynamics of the predicted and actual catch of aquatic biological resources (ABR) in the Russian waters of the Bering Sea is analyzed. With the tendency to reduce the forecast figures for ABR catch, their actual catches increased. On average, the annual catch of marine fish, including salmon, reached 602 thousand tons, which is 65 times more than the average number of years of invertebrates (9.3 thousand tons). The invertebrate fishery is actively developing: in 2000–2009 Their average annual catch was 5.1 thousand tons, in 2010–2015–16.1 thousand tons. The growth of catches was shown by the Commander squid, blue king crab, snow crab and bairdi tanner crab. The basis of the catch of marine fish was represented by cods, salmonids, herrings, righteye flounders and frenadiers, totaling 98.6 % of the catch, or 594 thousand tons per year. The catches of fish of other families in some years did not exceed 22.4 thousand tons, with an average catch of 8.1 thousand tons per year. Since2010, there has been a significant increase in catches of sculpins, greenlings, softnose skates, and to a lesser extent the production of smelts and rockfishes increased. When comparing the current catch of fish and the results of past fisheries (1910–2000) in the western part of the Bering Sea, an increase was observed in the fishing indices halibuts, greenlings, grenadiers, softnose skates, sculpins, and smelts. The current dynamics of the catch of marine fish and invertebrates is due to the natural fluctuations of the ABR stocks and the changes in the fishing industry occurring in historical perspective. For most ABR, there has been a trend towards an increase in recommended and actual catches, which suggests a favorable state of stocks of fish and invertebrates and an increase in their efficient use. The current state of fisheries in the western part of the Bering Sea indicates the absence of a significant field press on most fish and other objects
