摘    要:根据1997~2000年东海区底拖网渔业资源调查资料,分析和讨论了东海区小型鱼类的种类组成和季节变化。结果表明,东海区小型鱼类共有98种,优势种为发光鲷(Acropomajaponicum)、鳄齿鱼(Champsodon capensis)、鳀鱼(Engraulis japonicus)、七星底灯鱼(Benthosema pterotum)、细条天竺鲷(Apogon lineatus)、尖牙鲈(Synagrops japonicus)、黄鲫(Setipinna taty)、麦氏犀鳕(Bregmaceros macclellandi),各季节小型鱼类出现种类数及出现频率变化较小,渔获尾数和渔获质量变化显著。

关 键 词:小型鱼类  东海区  种类组成  季节变化

Abstract:According to the data selected from bottom trawl fishery resource monitoring in the East China Sea from 1997 to 2000,the species composition and seasonal variation of small-sized fish were analysed.The results indicated that there were 98 species of small-sized fish in the East China Sea,the dominant species were lanternbelly(Acropoma japonicum),gaper(Champsodon capensis),Japanese anchovy(Engraulis japonicus),skinnycheek lanternfish(Benthosema pterotum),cardinal fish(Apogon lineatus),blackmouth splitfin(Synagrops japonicus),scaly hairfin anchovy(Setipinna taty),macclelland's codlet(Bregmaceros macclellandi).Every season the species and occurrence frequency of small-sized fish changed a little,but the abundances and biomasses changed greatly.
Keywords:small-sized fish  the East China Sea  species composition  seasonal variation
