中文摘要:
      大黄鱼、小黄鱼和带鱼,是中国近海最重要的三种传统经济鱼类。本文主要论述了它们的分布,洄游和生物学特性,以及1955~1984年期间的开发利用经过和产量、资源变化。作者认为:近期这三种鱼产量的剧烈波动和种群年龄结构的显著变化,主要是由于过去20~30年捕捞过度引起的。根据实践经验,把长寿命鱼种的最适年可捕量定为1/3·M·Pf(种群可捕资源)或1/3·5·M·B6更为妥当。如果期望本海区渔业资源状况得到根本好转,必须对目前的捕捞强度作大幅度压缩。而要实现这一点,前面还有大量的社会、经济和立法问题亟待解决,且需国际上更广泛的协作。
英文摘要:
      Large yellow croaker Pseudosciaena crocea, little yellow croakerP.polyactis and largehead hairtail Trichiurus lepturus were three most impotantcommercial fishes in Chinese marine fishery. This paper mianly deals with the dis-tribution, migration of these fishes and their biological characteristics. The paper alsolooks back the process of exploitation and the changes in the yield and abundance ofresources from 1955 fo 1984. The conclusion points out that the violent fluctuationin the yields and the remarkable changes in the population structure were mainly dueto overfishing during the receni 20--30 years. It is more soitable to define the potential yield of long life-span fishes as 1/3 .M.P, (fishable population abundance)or 1/3. 5.M. B. according to our own experiment. In order to improve radically thefish resource status of the sea area, recent fishing intensity should be reduced on alarge scale. To realise this, a great number of problems should be solved such as thoseconcerned with socity, economics and legslation as well as international cooperationwith other countries or regions.
