福建省鳀鳁鱼、带鱼和毛虾年生产量非周期性彼此交替变化规律及其变化原因的探讨

ALTERNATIVE CHANGES OF ANNUAL CATCH OF ANCHOVY, SARDINE, HAIRTAIL AND ACETES FISHERIES IN FUJIAN PROVINCE AND ITS VARIATION MECHANISMS

鳀鳁鱼、带鱼和毛虾是福建省三大主要渔业资源,年产量都在2.5万吨以上,尤其鳀鳁鱼,最高年产量超过6.7万吨,而近来跃居首位,因而搞清福建海区鳀鳁鱼年生产量变化规律,及其上述三大渔业资源变化相互间关系,对于合理利用其资源和指导当前该海区捕捞生产具有重要意义。笔者根据有关资料,试对上述重要问题,作一些初步分析研究,提出一些粗浅的看法。

Anchovy, Sardine, Hairtail and Acetes fisheries are the most importante fishery resources of Fujian Province, their annual catches are more than 25 thousand tons respectively. In recent years, Anchovy and Sardine fisheries became predominance with an annual catch of more than 67 thousand tons. It was found that the hydrological and meteorological anomalies with related to the El-Nino events along the Min-Je coastal water were closely associated with the yield of Anchovy and Sardine fisheries, and also the alternative changes of annual catch among Anchovy, Sardine, Hairtail and Acetes fisheries. Therefore, it is necessary to study the relation between the fishery and environmental variations from the ecological point of views for the benefit of fisheries and resources utilization.
