摘要
本文介绍了1980年至2019年对堪察加西海岸黄貂鱼捕捞动态、生物量和大小组成的长期研究结果。正如我们所展示的，近年来，大部分黄貂鱼是在堪察加-库里尔斯卡亚地区捕获的。他们提取的主要工具是底层，占82.7%。5年的多年平均生物量为3 071.7 t (1996-2000) ~ 12 323.6 t(1986-1990)，平均为5 954.0 t。由于蓄积量的原因，最重要的物种是斑竹、白桦和紫桦。
NEW DATA ON FISHERIES AND STOCKS OF STINGRAYS (FAMILY ARHYNCHOBATIDAE) FROM WESTERN COAST OF KAMCHATKA
The results of long-term studies of fishing catch dynamics, biomass and size composition of stingrays off the western coast of Kamchatka from 1980 to 2019 are presented. As we show, in recent years the largest part of stingrays has been caught in the Kamchatka-Kurilskaya subzone. The main tool of their extraction is the bottom layer, as it made 82.7%. The multiyear biomass averaged over 5 years ranged from 3 071.7 tons (1996–2000) to 12 323.6 tons (1986–1990), and made 5 954.0 tons on average. The most significant species due to the stock volume are Bathyraja maculata, B. parmifera, and B. violacea.
