| 摘 要： | 根据2003~2004年西北太平洋秋刀鱼资源调查结果,对西北太平洋秋刀鱼渔场分布及其与海水表层温度(SST)的关系进行分析。结果表明,7~9月西北太平洋秋刀鱼渔场主要集中在40.5°N~44.5°N、151.5°E~158°E,SST为10℃~19℃,捕捞群体以中大型个体为主;各月最高产量及最大CPUE时的SST各不相同,渔场的形成和丰度与亲潮和黑潮的势力强弱及其分布密切相关。经K-S检验,结果表明,各月SST与产量及样本平均体长、平均体重的差异均不显著。这些渔场可作为我国远洋鱿钓渔业的兼作渔场。

| Abstract: | Based on the result of surveying Pacific Saury (Cololabis saira) in northwest Pacific in 2003～2004,this paper analyzed the relationship between the distribution of fishing ground of Pacific Saury and SST.The result showed that the fishing ground of Pacific Saury in northwest Pacific mainly concentrated in the area 40.5°N～44.5°N、151.5°E～158°E,and SST was between 10°～19°C from July to August in a year.Fishing population were mainly the large and medium individuals.There were differences of the SST in each month during the maximum yield and the greatest CPUE.Forming and abundance of the fishing ground were closely related to the strong and weak force of Oyashio and Kuroshio and their distribution.The result of K-S analysis showed that the differences between SST and catch and average body length and body weight of sample are not obvious.These fishing grounds may be used as the alternant fishing ground of distant water jigging fishery in our country. |
