摘　　要：2010年1～5月和8～11月在闽南海区桁杆虾拖网作业渔船上每月采样一次,分析样品9批,样品数量15833个,累计重量79.66kg。对渔获物进行种类鉴定、组成分析,结果表明:闽南渔场桁杆虾拖网作业渔获种类共有62种,其中鱼类35种、虾类17种、蟹类4种、头足类4种、口足类2种;渔获物以虾类为主,占总渔获重量的69.85%、鱼类占17.09%、口足类占11.00%、头足类占1.94%、蟹类占0.11%。虾类渔获以哈氏仿对虾(Parapenaeopsis hardwickii)为主,占虾类渔获重量的比例为58.29%,主要出现在1～5月和10～11月,其次鹰爪虾(Trachypenaeus curvirostris),占29.13%,主要出现在8～9月。8月份渔获物中出现较多幼鱼,其中二长棘鲷(Parargyrops edita)幼鱼重量比例达13.70%。总体而言,桁杆虾拖网作业对资源利用比较合理。9 batchs of catch samples （the total weight was 79. 66kg, the total numbers was 15833 individuals）, were collect- ed from shrimp beam trawl from January to May and August to November in 2010 in Miunan fishing ground. By species identifica- tion and catch sample analysis, the results showed that the total species of catches were 62 kinds, including 35 kinds of fishes, 17 kinds of shrimps, 4 kinds of crabs, 4 kinds of cephalopod and 2 kinds of squillas. Based on weight pmportiun analyzing, shrimps was the main catch species, which accounted for 69. 85 percentages, fishes 17.09 percentages, squilla 11.00 percenta- ges, cephalopod 1.94 percentages and crabs 0. 11 percentages.
