摘　　要：柔鱼(Ommastrephes bartramii)渔场位于西北太平洋的黑潮-亲潮过渡带,海域内涡旋活动剧烈。然而,中尺度涡如何影响西北太平洋柔鱼渔场仍不清楚。为此,依据建立的2009—2018年西北太平洋海域涡旋逐日追踪数据集及渔业统计资料,利用归一化方法初步分析了柔鱼渔场与距涡心距离之间的关系,并利用广义加性模型探索了捕捞位置、距涡心距离及涡旋发展阶段对柔鱼CPUE分布的影响。结果表明:1)反气旋涡内柔鱼总捕捞努力量、产量和平均CPUE均较高,单位面积内产量也较高,表明在反气旋涡内部具有较高的柔鱼资源丰度,同时CPUE随距气旋涡涡心距离的增加呈现上升趋势,反气旋涡内则呈下降趋势;2)气旋涡和反气旋涡内柔鱼CPUE与经度的关系不同,气旋涡CPUE在150°E至158°E之间较高,而反气旋涡周围的CPUE则是随着经度升高而升高,原因可能与不同海况渔场形成机制不同有关;3)柔鱼CPUE与气旋涡发展阶段负相关,与反气旋涡发展阶段正相关,CPUE在反气旋涡发展末期明显上升,可能与反气旋涡减弱消散过程中的短暂上升流或混合作用有关。研究结果可为西北太平洋柔鱼渔场的资源评估与开发提供参考。Mesoscale eddies are marine mesoscale processes characterized by rapid rotation,which are ubiquitous in the global ocean and have a significant impact on marine ecology.As a short-lived pelagic cephalopod,Ommastrephes bartramii population is extremely sensitive to changes in marine environment.O.bartramii fishing ground is located in the Kuroshio-Oyashio transition zone in the Northwest Pacific Ocean,where eddy activities are intense.However,a comprehensive understanding of how mesoscale eddies affect O.bartramii populations in the Northwest Pacific is still lacking.Based on the established daily eddy tracking data set and fishery statistics data in the Northwest Pacific Ocean from 2009 to 2018,the relationship between O.bartramii fishing grounds and the distance from the eddy center was preliminarily analyzed by using the normalization method.The generalized additive model(GAM)was used to explore how the CPUE distribution was affected by fishing position,distance from eddy center and eddy development stage.The results showed as follows:1)The total fishing effort,yield and average CPUE were higher in the anticyclonic mesoscale eddies,and the fishing effort and yield per unit area were also higher,indicating that there was a high abundance of O.bartramii resources in the anticyclonic mesoscale eddies.Meanwhile,CPUE increased with the increase of the distance between the center of cyclonic mesoscale eddies and decreased for the anticyclonic mesoscale eddies.2)The relationship between CPUE and longitude was different between anticyclonic mesoscale eddies and cyclonic mesoscale eddies.CPUE in the cyclonic mesoscale eddies was higher between 150°E and 158°E,while CPUE around anticyclonic mesoscale eddies increased with the increase of longitude,which might be related to the different formation mechanisms of fishing grounds in different sea areas.3)CPUE was negatively correlated with the development stage of cyclonic mesoscale eddies and positively correlated with the development stage of anticyclonic mesoscale eddie
