摘要
在浙南飞云江口海域5月份棘头梅童鱼(Collichthys lucidus)繁殖期,进行了2次休闲渔船渔获物调查。调查结果表明,个体数量的优势种主要为棘头梅童鱼、三疣梭子蟹(Portunus trituberculatus);结合社会调查结果对棘头梅童鱼资源量变化进行分析后发现,飞云江口海域的棘头梅童鱼的资源量大幅增加。通过2次调查发现,休闲渔船渔获物调查简单方便,可作为海洋渔业资源调查的补充,尤其适宜特定海域特定渔业资源的长期跟踪调查。
In May during the spawning season of the Collichthys lucidus in the Feiyunjiang Estuary waters of southern Zhejiang,two recreational fishing vessel catch surveys were conducted.The survey results indicated that the dominant species by abundance were primarily the Collichthys lucidus and the Portunus trituberculatus.Analysis combining social survey data revealed a significant increase in the Collichthys lucidus population in the Feiyunjiang Estuary.The two surveys demonstrated that recreational fishing vessel catch surveys are simple and convenient,making them suitable as a supplementary method for marine fishery resource investigations.They are particularly appropriate for long-term monitoring of specific fishery resources in defined marine areas.
