摘 要：
依据2016年秋季西北太平洋公海灯光敷网探捕调查采集的数据,对其渔获组成及主要种类生物学特性进行了初步研究。结果表明:调查期间平均日产13.65 t,最高出现在10月,为19.14 t,最低出现在8月,为10.58 t;CPUE平均为1 822.4 kg/h,最高出现在10月,为2 492.2 kg/h,最低出现在9月,为1 412.8 kg/h。渔获种类隶属于8目12科16属16种,其中鱼类7目11科14属14种、头足类1目1科2属2种;渔获种类总质量组成中,日本鲭(Scomber japonicus)占绝对优势,产量所占比例高达72.0%,其次是远东拟沙丁鱼(Sardinops sagax)、秋刀鱼(Cololabis saira)和柔鱼(Ommastrephes bartrami),分别占比19.41%、7.94%和0.58%。群体组成中幼鱼数量比例较大,性腺成熟度均较低,对幼鱼的损害较为严重。

摘 要：
Based on the data investigated by light-liftnet in the Northwest Pacific Ocean in the autumn of2016,the catch composition and biological characteristics were studied.The results showed that the average daily yield was 13.65 t,the highest was 19.14 t appeared in October,the lowest was 10.58 t appeared in August.The average CPUE was 1 822.4 kg·h~(-1).The highest value was 2 492.2 kg·h~(-1) appeared in October,and the lowest value was 1 412.8 kg · h~(-1) appeared in September.The catch species was sixteen,which belonged to 8 order,12 family and 16 genus.The main catch species were Scomber japonicus,Sardinops sagax,Cololabis saira and Ommastrephes bartrami,accounted for 72.00%,19.41%,7.94% and 0.58% in the total catch,respectively.Juvenile fish was accounted for a large proportion in population composition,and the rank of gonad maturity was at a lower level,which indicated that juvenile fish suffered severely damage.
