厦门东海域流刺网渔获鱼类种类组成及其多样性分析

Study on fish species composition and diversities captured by drift net from Xiamen eastern sea

2005年7月至2006年6月对厦门东海域的流刺网渔获鱼类的种类组成及其多样性进行采样分析.总共获得鱼类67种,隶属于14目40科50属.以鲈形目种类最多,共计29种,占总数的43.3%.主要的优势种有:皮氏叫姑鱼、黄鳍鲷、杜氏棱鳀、棱鮻、中华海鲶、斑鰶、黄斑鲾和褐蓝子鱼等.渔获种类的季节变化比较明显,种类的月更替率比较高,与海洋表层水温变化有关.

Fish samples captured by drift net from Xiamen eastern seawaters from July 2003 to June 2004 were analyzed. The result showed that there were at least 67 species of fish captured by drift net, which belongs to 50 genuses in 40 families of 14 orders. The species of Perciformes is the most abundant accounting for 29 species and for 43.3% of the total species. The dominant species were Johnius belengeri, Sparus latus, Thrissa dussumieri, Liza carinatus （Cuvier et Valenciennes）, Clupanodon punctatus （Schlegel）, Leiognathus bindus , and Siganus fuscescens, etc. The species composition of fish varied significantly with seasons, particularly high with monthly alternatives, and associated with changes of water temperature.
