中国大陆阿根廷滑柔鱼鱿钓渔业CPUE标准化
CPUE standardization of Illex argentinus for Chinese Mainland squid-jigging fishery in the southwest Atlantic Ocean
摘要
Abstract
Illex argentinus is one of the most important squid-jigging fishery of Chinese Mainland in Southwest Atlantic Ocean.It is necessary to standardize the catch per unit effort (CPUE) in the stock assessment.Generalized linear models (GLM)and generalized additive models (GAM)were used to standardize catch per unit effort(CPUE) of Illex argentinus for Chinese squid-jigging fishery in the southwest Atlantic Ocean based on the production data from 2000 to 2010 collected by Chinese Squid-jigging Technology Working Group and the environmental variables including sea surface temperature (SST),sea surface height (SSH) and chlorophyll-a (Chl-a).The GLM analysis indicated that the importance of four variables ranked by decreasing magnitude:Year,Latitude,Year × Latitude and SST.However,the GAM showed that the model including Year,Month,Longitude,Latitude,SST,SSH,Year × Latitude and Year × Longitude was the optimal model based on AIC and could explain 49.20％ of the variance in nominal CPUE.GAM analysis indicated that high CPUEs were found in the area between 46.5° and 48.5°S at SST ranging from 12 ℃ to 16 ℃ and SSH ranging form-20 to 20 cm in summer.In this study,GAM tended to be more suitable than GLM in analysis of CPUE.关键词
