Relationship between neon flying squid Ommastrephes bartramii fishery distribution patterns and eddy kinetic energy in Northwest Pacific Ocean
-
摘要: 本研究利用卫星高度计数据计算海洋涡动能(Eddy Kinetic Energy,EKE),根据2010–2016年中国远洋渔业协会鱿钓组提供的西北太平洋柔鱼(Ommastrephes bartramii)渔业生产数据,分析柔鱼渔场的EKE分布特征以及黑潮延伸体EKE的时空变化对柔鱼渔场分布的影响。结果显示,柔鱼渔场的EKE与单位捕捞努力量渔获量(Catch Per Unit Effort,CPUE)呈显著负相关(P < 0.01),EKE对CPUE的有效影响范围为0~1 500 cm2/s2,最适宜EKE范围为25~150 cm2/s2。黑潮延伸体EKE强度由西向东递减,与CPUE年平均呈负相关,相关系数为0.81(P < 0.05)。按黑潮延伸体经度范围分为4个子区域,CPUE月平均纬度重心响应该月EKE强度最高的子区域。盛渔期8–10月渔场距离黑潮延伸体在800~1 000 km范围内时,CPUE随距离增加而增大,其中最适宜的距离范围为850~950 km。研究表明,当黑潮延伸体路径弯曲多变时,EKE增大,而柔鱼CPUE变低,渔场位置越偏北。Abstract: In this study, the eddy kinetic energy (EKE) derived from satellite altimeter data and the fishery data during 2010−2016 obtained from the Chinese Squid-jigging Science and Technology Group, are used to analyze the spatial and temporal relationship between the Kuroshio Extension EKE and fishing ground distribution. The results show that the catch per unit effort (CPUE) is negatively related to the EKE of fishing ground in the range of 0–1 500 cm2/s2, the most suitable EKE is between 25–150 cm2/s2. Furthermore, the Kuroshio Extension EKE decreasing from west to east, is correlated with CPUE with the high correlation coefficient of 0.81. According to the longitudinal range, the Kuroshio Extension is divided into four sub-areas, and the monthly average latitudes of fishing ground centroids respond to the sub-areas with the highest EKE in the same month. When the distance (DIST) from fishing grounds to the Kuroshio Extension in the range of 800–1 000 km, CPUE increases with the DIST, and the most suitable DIST from August to October is between 850−950 km. When the Kuroshio Extension path has complicated meanders, EKE is high, while the CPUE is reduced and the fishing grounds move northward.
