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。
According to the production data of the anchovy fence and the environmental data of the CATSAT system in the Western and Central Pacific Ocean from 2009 to 2011 in our country, the environmental variables closely related to the catches were screened by KS test, and then the average catch-range range . K-S test indicated that the catch rate is closely related to environmental variables such as 0m, 20m, 30m, 50m, 75m, 125m, 150m, 200m, 250m, 300m water temperature, thermocline depth and 200m salinity. The suitable environmental factors and their ranges of the selected fishing grounds are as follows: 0m water temperature 29.9 ~ 31 ℃, 20m water temperature 30.1 ~ 31.4 ℃, 30m water temperature 30.3 ~ 31.3 ℃, 50m water temperature 30.1 ~ 31.7 ℃, 75m water temperature 29.8 ~ 31.7 ℃, 150m water temperature 22.8 ~ 27.1 ℃, 200m water temperature 15.3 ~ 21.8 ℃, 250m water temperature 12.5 ~ 15.4 ℃, 300m water temperature 9.6 ~ 11.7 ℃, thermocline depth 71 ~ 140m, 200 salinity 34.71 ~ 35.40. The findings can be used not only to improve fishery forecasting but also to guide fish production practices directly.
