摘要
2014年9月笔者对衢山岛海域渔业资源进行调查,分析了衢山岛周围海域渔业资源的种类组成、数量分布、群落结构。结果表明,该海域共捕获游泳生物29种,隶属8目23科,主要优势种为脊尾白虾和葛氏长臂虾。秋季的重量多样性指数大于尾数多样性指数,调查海域游泳生物多样性指数和丰度指数偏低,均匀度分布水平低。
Fishery resources in sea area around Qushan Island in Sep.2014 were investigated, the species composition, quantity distribution, community structure of fishery resource were analyzed.The results showed that a total of 29 nekton species were captured, belonging to 23 fami-lies and 8 orders.The dominant species were Exopalaemon carinicauda and Palaemon gravieri.Weight diversity index was greater than number diversity index in autumn, so the biodiversity, abundance and the evenness index distribution were all low in the survey sea area.
