闽东渔场是我国东南沿海带鱼群南北洄游必经之地,每年冬季大批鱼群由浙江沿海南下进入本渔场,形成冬季带鱼汛,其产量一般占本渔场带鱼年产量的80%左右,最高占90%以上,是本渔场带鱼生产的主要渔汛。本文根据1959—1966年和1971—1979年计十六年对10,034尾冬汛带鱼进行生物学测定的资料,就越冬鱼群的群体结构及其特性加以分析,提供有关单位参考。
The fishing ground of Mindong is a necessary part of north-south migration of the octopus in the southeast coast of China. Each year a large number of fish in winter come into the fishery from south of Zhejiang along the coast to form winter flooding. The output of octopus is about 80% Over 90% is the main fishing season for octopus production in this fishing ground. Based on the data of 10,034 fish in the winter flood season from 1959 to 1966 and from 1971 to 1979, the population structure and characteristics of the overwintering fish population were analyzed and the relevant units were provided for reference.
