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。
According to the statistical data and surface temperature data of Illex argentinus, a Chinese squid fishing in Southwest Atlantic from January to May in 2003, the author analyzed the monthly output, the distribution of average daily output and the relationship with surface temperature. The results showed that the operating fishing grounds were concentrated in the waters around 45 ° S and 60 ° W with large fluctuations in monthly output and average daily output. The main fishing season was between January and April. Appropriate operating surface fishing table temperature is 8 ~ 13 ℃, and after K-S test. From January to May over the passage of time, suitable for a downward trend in the table temperature. Studies show that the fishing grounds are mainly located at the intersection of the Falklands cold current and the Brazilian warm current, and close to the western side of the Falklands cold current.
