摘    要:2010年4月和5月,采用灯光围网作业在南沙群岛的永暑、赤瓜、美济、安塘、华阳和南薰等6座珊瑚礁水域及礼乐滩和西南渔场进行了2个航次的渔业资源调查。结果显示,灯光围网主要渔获品种为蓝圆鲹、鸢乌贼、扁舵鲣、裸狐鲣、珍鲹和金枪鱼类等品种,最高产量5.05 t,单位网次产量CPUE为1.256 t/net,渔获率约154.95 kg/h。永暑礁和赤瓜礁水域产量最高,且各个礁区、各月份渔获差异显著,金枪鱼类主要集中在永暑礁与赤瓜礁附近海域,在其他海域没有捕获,还需在不同水域和季节加强调查。

关 键 词:南沙群岛  灯光围网  渔业资源  春季

Abstract:In April and May 2010, two survey cruises were carried out in Nansha islands by light purse seiner. The result shows that: a total of 18 species were caught, major species include Decapterus maruadsi, Symplectoteuthis oualaniensis, Gymnosarda unicolor , Euthynnus pelamis and Caranx ignobilis etc. The maximum catch reaches 5.05 t, catch per net(CPUE) was 1.256 t/net , mean catch rate was 154.95 kg/h. Yongshu and Chigua reefs have higher catch and catch rate than other areas. Different species and catch happened in different reefs and months. Tuna was caught only at Yongshu and Chigua reefs. We need more research in other places and seasons.
Keywords:Nansha islands  light purse seiner  fish resources  spring season
