中文摘要：根据2011—2015年南海海域灯光罩网渔船捕获的鸢乌贼(Sthenoteuthis oualaniensis)样品,利用FisatⅡ软件对南海鸢乌贼群体的生长死亡系数进行估算。结果显示:南海没有大型群鸢乌贼个体,且雌性个体(12.05 cm)比雄性个体(10.91 cm)大;南海北部和南部的鸢乌贼均呈正异速生长,胴长和体质量关系b分别为3.470~3.605和3.379~3.773;生长参数K反映了南海北部更适合于雄性鸢乌贼生长;南海南部海域鸢乌贼雌性和雄性总死亡系数相差不大,开发较为均衡;南海北部海域鸢乌贼雌性总死亡系数远小于雄性,显示该海域鸢乌贼未能充分开发。从渔业资源开发的角度分析得出,渔业政策偏向于开发南海南部鸢乌贼资源,使得北部鸢乌贼资源未能充分开发,不利于南海鸢乌贼资源的可持续利用。

外文摘要：According to the purpleback flying squid(Sthenoteuthis oualaniensis)collected by light attracting falling-net in the South China Sea(SCS)in 2011-2015,the squid individual growth and mortality in the SCS were estimated by FisatⅡsoftware.The results showed that there were no large individuals in the SCS,and females(12.05 cm)were larger than males(10.91 cm).Growth coefficient b of the squid ranged from 3.470 to 3.605 in the northern sea area and 3.379 to 3.773 in the southern sea area,and there was positive allometry.The growth parameter K indicates that the northern part of the SCS was suitable for the growth of males.The total mortality of the female(1.84)and male(1.76)squids had little difference and the development was relatively uniform in the southern sea area.The total mortality of female squids(0.60)was much less than that of males(4.83)in the northern sea area,so squids here were not fully developed.From the fishery resources development,fishery policies tend to develop the southern squid resources of the SCS,which makes the northern squid resources not fully developed,which is not conducive to the sustainable utilization of the purpleback flying squid resources in the SCS.
