| 摘 要： | 根据1971-1982年渤、黄、东海的统计资料研究近海白姑鱼数量空间格局的变化。研究结果表明:我国东黄渤海白姑鱼渔场一共有3类:即产卵场渔场,主要位于春季东海沿海水域;索饵场渔场主要位于夏季的东海北部和黄海南部;越冬场渔场有两个,北部越冬场在冬季的东黄海外海,南部越冬场主要集中在东海南部近海。自1978年后,东海白姑鱼产量明显上升,并且超过黄渤海区。通过对不同渔场白姑鱼产量对整个渔场产量贡献的分布格局分析显示,东海白姑鱼主要渔场有两个:其中东黄海渔场位于长江口附近,渔讯为5-9月;黄渤海的渔场位于黄海北部近海和渤海中央,主要渔讯在11月。在渔汛时,白姑鱼渔场中的鱼群密集,产量集中,是捕捞白姑鱼的理想渔场。1971-1982年白姑鱼鱼群的分布与近年来分布格局类似,因此论文有关白姑鱼渔场特征、渔汛时间和渔场贡献率分布格局模式等重要结论对现今白姑鱼资源保护仍然具有重要的参考价值。

| Abstract: | The distribution and spatial patters of white-croaker fishing grounds in Bohai,Yellow and East China Seas were studied according to the capture production from 1971 to 1982.It shows that there are three types of white-croaker fishing ground,that is the spawning grounds which were mainly located in coastal waters of the East China Sea during spring,feeding grounds which were concentrated on the northern part of the East China Sea and the southern of the Yellow Sea during summer,and the wintering grounds,incl... |
