摘要
根据舟山新吉利远洋渔业有限公司2艘探捕船2007年与2008年的探捕资料,结合表温数据,对西南大西洋公海阿根廷滑柔鱼产量的时空分布进行了研究。结果表明,西南大西洋公海阿根廷滑柔鱼的渔期为1～6月,其中3～5月为高产期。渔场主要在45°～47°S、60°～61°W海域。产量重心位置总体呈较强的季节性分布,即两年的1～3月为一类,而4～6月另成一类。渔场表温升高是2008年产量重心南移的主要因素之一。
Based on the yield data of two Chinese squid fishing vessels of Zhoushan Xinjili Ocean Fisheries Co., Ltd and the sea surface temperature from 2007 to 2008, the spatio-temporal distribution of catch of the Illex argentinus in the high sea of the Southwest Atlantic Ocean was analyzed. The results showed that the fishing period was from Jan. to Jun, and the main period was from Mar. to May. The fishing ground was mainly enveloped by 45°-47°S, 60°-61°W. The weight position seemed to be seasonal, and it shifted southwardly mainly due to the surface temperature increase of the sea in 2008.
