摘　　要：根据2012年1-4月我国鱿钓船西南大西洋公海阿根廷滑柔鱼资源探捕数据,结合历年调查资料和表温资料,对其产量分布与表温关系进行分析。结果显示:2012年西南大西洋阿根廷滑柔鱼产量主要集中在1、2两个月份,占探捕调查总产量的65.2%,其中产量最高的月份为2月份,CPUE达7.93 t/d;在适温范围内CPUE与SST之间具有较高的相关性,表现为CPUE随SST值升高而增大;从1-4月探捕海区情况来看,中心渔场渔区主要集中于45.25°～47.25°S,60.00°～60.75°W之间,随着时间的推移,中心渔场有自北向南移动的趋势。Based on the capture data of China′s squid fishing boat in southwest Atlantic Ocean,combined with the recent years of survey data and surface temperature data,analyzing the distribution of production of Illex argentinus in southwest Atlantic.The results are as follows: 2012 southwest Atlantic I.argentinus production mainly concentrated in Jan.and Feb.,which production accounts for 65.2% of the total production of catch surveys,the highest capture month is February,CPUE up to 7.93;Within the fit temperature range,CPUE and SST shows higher relativity.Bring out CPUE increase with higher SST value.Statistic the output from Jan.to Apr.We found that the central fishing ground fishing areas are mainly concentrated between the 45.25 ° S to 47.25 ° S,60.00 ° W to 60.75 ° W,as time goes on,moving from north to south.
