摘要: 根据舟山新吉利远洋渔业有限公司与宁波远洋渔业公司共4艘调查船的调查资料，结合表温数据，对2008年西南大西洋公海阿根廷滑柔鱼产量分布与表温关系进行了研究。结果表明，2008年的主汛期为3—5月，作业渔场主要在45?~47?S、60?W以西、阿根廷专属经济区线以东海域。作业渔场的产量分布与表温存在一定的关系，1—6月份的适宜表温为6.0~14.0 ℃，其月间变化总体呈先升后降的趋势。与2000年、2003年相比，2008年的主要作业渔场明显偏南，这主要与其表温较高有关。

Abstract: Based on the production data of four Chinese squid investigating vessels, associated with SST (sea surface temperature ), it was analyzed on the relationship between the Illex argentinus production distribution and SST in the High Sea of the Southwest Atlantic Ocean in 2008. The results showed that the main fishing period was from March to May in 2008, the fishing ground located on 45?~47?S, west of 60?W and east of Argentine Exclusive Economic Zone. The production distribution and SST had close relationship. The suitable temperature was between 6.0 ℃ and 14.0 ℃, and its monthly variation took on the trend increased first and decreased afterwards. Compared with 2000 and 2003, the fishing ground moved to the south obviously in 2008, this is related to its increasing SST.
