摘　　要：根据2003年1～5月中国鱿钓船在西南大西洋捕捞生产阿根廷滑柔鱼Illex argentinus的统计数据和表温资料,对其各月产量、平均日产量的分布以及与表温的关系进行分析.结果表明,作业渔场集中在45°S、60°W附近海域,各月产量和平均日产量有较大波动,主渔汛期在1～4月间.作业渔场的适宜表温为8～13℃,并经过K-S检验.1～5月随着时间的推移,适宜表温有下降的趋势.研究表明,作业渔场主要分布在福克兰寒流与巴西暧流交汇处,并靠近福克兰寒流的西部一侧.The relationship between the daily catch distribution of squid Illex argentinus and sea surface temperature （SST） was studied on the basis of the database of Chinese mainland squid fishery and sea surface temperature in the Southwestern Atlantic from January to May in 2003. The results indicated that the fishing ground was mainly concentrated in the waters near 45°S, 60°W. The monthly production and daily catch fluctuated greatly, and the fishing mainly occurred from January to April. The optimal SST for fishing was 8-13℃ and changed with the season by K-S test. The fishing ground was formed in the transitional zone between Falkland current and Brazil current, especially in the west side of Falkland current.
