摘要
2010年7月利用灯光罩网和延绳钓对南沙北部海域进行了初步的渔业资源调查,报道了该海域的鸢乌贼(Symplectoteuthis oualaniensis)和金枪鱼的渔获与分布状况。灯光罩网平均CPUE 63.90 kg/网,主要渔获物为鸢乌贼,占总产量的67.57%,平均胴长122 mm,质量89.6 g;延绳钓平均CPUE为18.19 kg/百钩,其中大目金枪鱼(Thunnus obesus)3.24 kg/百钩、短鳍斜齿鲨(Scoliodon Palasorrah)10.46 kg/百钩,渔获尾数较多的为帆蜥鱼(Alepisaurus ferox)和黑魟(Dasyatis atratus),分别占总数的39.13%和26.09%。提出南沙金枪鱼捕捞采用延绳钓与灯光罩网联合方式的建议。
