中文摘要：根据我国某公司2009-2011年在中西太平洋海域鲣鱼围网生产数据和CATSAT系统渔场环境数据,采用K-S检验筛选出与渔获关系密切的环境变量,然后采用均值比较确定适宜的渔获环境范围。K-S检验认为,渔获量与0m、20m、30m、50m、75m、125m、150m、200m、250m、300m水温、温跃层深度、200m盐度等环境变量关系密切。选择中心渔场的适合环境因子及其范围为:0m水温29.9～31℃、20m水温30.1～31.4℃、30m水温30.3～31.3℃、50m水温30.1～31.7℃、75m水温29.8～31.7℃、150m水温22.8～27.1℃、200m水温15.3～21.8℃、250m水温12.5～15.4℃、300m水温9.6～11.7℃、温跃层深度71～140m、200盐度34.71～35.40。研究结果不仅可用于改进渔情预报工作,而且可直接用于指导渔业生产实践。

外文摘要：The relationships between catch and environmental variants were assessed by Kol-mogorov-Smirnov tests based on skipjack Katsuwonus pelamis purse seine data in the West- ern-Central Pacific Ocean from Chinese commercial fishery in 2009-2011. Suitable environ- mental intervals were determined by comparison of means. With Kolmogorov-Smirnov tests, catch was closely related to water temperature in 0m, 20m, 30m, 50m, 75m, 125m, 150m, 200m, 250m, and 300m layers, thermocline depth, and salinity in 200m layer. The suitable water temperature interval was 29.9-31℃ in 0m layer, 30.1-31.4℃ in 20m layer, 30. 3- 31.30℃in 30m layer, 30.1-31.7℃ in 50m layer, 29.8-31.7℃ in 75m layer, 22.8-27.1℃ in 150m layer, 15.3-21.8℃ in 200m layer, and 9.6-11.7℃ in 300m layer. The suitable thermocline depth was 71-140m. The suitable salinity interval was 34.71-35.40 in 200m layer. The results can be used to improve fishing ground forecast and operation.
