根据2012年8月~2014年6月“粤电渔42212”渔船的生产数据，分析了南海区大型钢质灯光罩网渔船的渔获组成和渔场渔期。结果显示，主要渔获种类为鸢乌贼（ Sthenoteuthis oualaniensis）、#科（ Carangidae）、鲭科（ Scombrida）、枪乌贼（ Loliginidae）和带鱼（ Trichiurus japonicus），分别占总渔获产量的69.8%、12.6%、7.3%、3.9%和3.5%。作业渔场可分为近海陆架区和外海深水区，其中陆架区渔获种类相对较多，包括科、枪乌贼、带鱼、鲭科等；而深水区渔获以鸢乌贼为主，其他种类相对较少。近海陆架区作业月份为8月至翌年2月，每月作业1~20 d，平均作业10 d，渔获率为370.5~3670.0 kg·d-1，平均渔获率1152.0 kg·d-1。深水区作业集中在2月~6月，每月作业1~30 d，平均作业13 d，渔获率为1000~10190 kg·d-1，平均渔获率4071.3 kg·d-1。相对于近海陆架区，灯光罩网渔业在外海深水区渔获效率更高、产量更大，在现有资源条件下应大力发展大型钢质灯光罩网渔船，积极开发南海外海渔业资源。

Based on the catch records of“YUE DIAN YU NO. 42212”from August 2012 to June 2014,we studied the catch composi-tion and fishing season by steel light falling-net fishing vessels in the South China Sea. The results show that Sthenoteuthis oualaniensis, Carangidae,Scombrid,Loliginidae and Trichiurus japonicas were the main catch species,accounting for 69. 8%,12. 6%,7. 3%, 3. 9% and 3. 5% of the total catch,respectively. The fishing ground could be divided into continental shelf waters and deep waters of high seas. Main catch species in shelf waters were Carangidae,Loliginidae,Trichiurus japonicas and Scombrida;the main catch spe-cies in deep waters was Sthenoteuthis oualaniensis,which was less diverse. The fishing season in shelf waters was from August to Feb-ruary in the next year(1~20 fishing days per month and 10 d averagely;the average catch per day in one month was 370. 5~3 670 kg·d-1 and 1 152. 0 kg·d-1 averagely). The fishing season in deep waters was from February to June(1~30 fishing days per month and 13 d averagely;the average catch per day in one month was 1 000. 0~10 190. 0 kg·d-1 and 4 071. 3 kg·d-1 averagely). Since the fishing operation in deep waters had higher productivity and more total catch than those in shelf waters,it is necessary to develop steel light falling-net fishing vessels to explore the fishery resources in deep waters of high seas.
