根据1998-2000年8～10月在150°～165°E海域我国北太平洋鱿钓生产数据以及海况资料,分析柔鱼中心渔场与海洋环境之间的关系,建立柔鱼渔场预报模型。结果显示,黑潮势力的强弱及其分支分布与柔鱼渔场形成关系密切。8～10月柔鱼作业渔场基本上处在黑潮第2、第3暖水分支的前锋。柔鱼渔场分布与月份、20℃等温线分布的关系密切。8～10月中心渔场的预报模型为:经度方向FGLong=141.535+1.8435×T;纬度方向FGLati=-8.461+1.165×T+(Lat155+Lat160)/2。
According to the data of squid production in North Pacific Ocean from 150 ° to 165 ° E from August to October 1998 from 2000 to 2000 and the sea state data, the relationship between the fishing ground and the marine environment of Ommastrephes bartrami was analyzed, and the forecasting model was established. The results showed that the strength and branch distribution of Kuroshio were closely related to the formation of Ommastrephes alba. 8 to October Ommastree fishing grounds are basically at the front of the Kuroshio 2nd and 3rd warm water branches. The distribution of Ommastrephes bartrami is closely related to the distribution of 20 ℃ isotherm in the month. The prediction model of the central fishing ground from August to October is: longitude direction FGLong = 141.535 + 1.8435 × T; latitudinal direction FGLati = -8.461 + 1.165 × T + (Lat155 + Lat160) / 2.
