摘要/Abstract

摘要： 为了初步掌握西北太平洋公海秋刀鱼渔场的变动规律，利用“欧亚1号”渔船2014年5月至11月的渔捞数据以及遥感手段获取的海洋表面温度（SST）数据，分析了秋刀鱼单位捕捞努力量渔获量（CPUE）的月份变化以及各月的CPUE空间均值分布与SST的关系。结果表明：11月份月平均CPUE值高于其他月份，达到3.18 t/h；9月至11月份的各月平均CPUE均高于5月至8月；产量分布在SST为9.5~17℃范围内，主要集中在12.5~14.5℃范围内，其比重约占62.5%，且不同季节的适宜作业温度有所差异；月平均CPUE最高值出现在7月份的160.5°E、46.5°N区域内，为5.90 t/h；各个月份中心渔场位置变化较大，呈现东北向逐渐偏移，再西南向逐渐偏移。

Abstract: In order to understand the varying regulattion of Pacific saury (Cololabis saira) in the high seas of the Northwest Pacific Ocean, this paper analyzed the monthly changes of catch per unit effort (CPUE) of saury, the relationship between spatial average value distribution of CPUE in each month and sea surface temperature(SST), according to the fishing data gained from May to November, 2014 in “OUYA No.1” fishing trawler and SST data obtained by remote sensing technology. The results showed that the average CPUE value in November was higher than that of the other month, reaching 3.18 t/h; and each month average CPUE values from September to November were higher than that of May to August. Output distribution where SST was within the range between 9.5~17℃, mainly concentrated in the scope of 12.5~14.5℃, with about 62.5% proportion. There were differences in suitable fishing temperature at different seasons; the highest monthly average CPUE appeared in July at 160.5°E and 46.5°N 2 regions with the value of 5.90 t/h. There were greater changes in the location of central fishing ground, moving gradually along northeast shift to southwest shift.
