Abstract

The status of the aggregation of the Pacific oyster Crassostrea gigas (Thunberg, 1793) in the Busse Lagoon (Sakhalin Island) was assessed in 2019. The uncontrolled harvesting of this bivalve species caused its abundance to decline. The total oyster stock in the lagoon is estimated at 24.1 t; the commercial stock is estimated at 3.8 t; the aggregation is dominated (84.4%) by nonharvestable individuals with a shell height smaller than 120 mm. For the conservation of the C. gigas population, it is suggested to restrict any use of oyster beds for 2–3 years until a new generation of oysters is produced.

太平洋牡蛎的状况，Crassostrea gigas（Thunberg，1793年），萨哈林岛布斯泻湖中的人口

摘要

在2019年评估了Busse泻湖（萨哈林岛）中的太平洋牡蛎Crassostrea gigas（Thunberg，1793年）的聚集状况。这种双壳类鱼类的无节制收获导致其丰度下降。泻湖中的牡蛎总存量估计为24.1吨。商业库存估计为3.8吨；壳层高度小于120毫米的不可采伐的个体主导了这一聚集（占84.4％）。为了保护长尾。（C。gigas）种群，建议限制使用牡蛎床2-3年，直到生产出新一代牡蛎为止。
