摘要
本文根据1986~1989年,对浙江近海(26°30'~31°30'N、125°E以西)拖虾调查资料,根据虾类的分布特点计算了标准拖网船数据,用密度法评估了主要虾类和总体的资源量和可捕量。其结果为:20~90米水涂海域的现存资源量为100.4千吨,可捕量为80.3千吨,其中哈氏仿对虾和鹰爪虾的数量最大。为合理利用和管理东海区浙江近海的虾类资源提供基础资料。
According to the shrimp trawl data of Zhejiang coastal area(west of26°30′~31°30′N,125°E)in l986~1989 and the characteristics of shrimp dist-ribution,the standardized trawl data were calculated.The resource andcatchability of main shrimps were estimated by using the density method.As the results,in the area at a depth of 20~90 meters,the current resourceabundance is 100.4 k tons and the catchable quantity 80.3 k tons;P. hardw-ickii(Wiers)and T. curvirostris(Stimpson)being lion share. These dataare useful in reasonable utilization and management of the shrimp resourceof Zhejiang coastal area.
