摘要: 利用2000—2008年中国鱿钓船在西南大西洋阿根廷滑柔鱼(Illex argentinus)的生产数据与海洋卫星反演资料,分析了近9年西南大西洋阿根廷滑柔鱼资源丰度的变化及其与主要的生态因子(海表温度和叶绿素a)的关系。结果表明:该鱼种的年平均资源丰度在近9年出现了较大变化,以2004年为转折点,之前呈下降的趋势,至2004年降至最低,2005年后逐年上升;在该时期,这两个生态因子与该鱼种资源丰度的变动存在一定的关系:2000—2003年该海域年均海表温度波动较大,但资源丰度较平稳,两者的变动之间未发现存在明显的关系,2004—2008年年均海表温度和资源丰度的变动表现为显著的负相关;2000—2004年年均叶绿素a与资源丰度的变动之间未呈现明显的相关性,2005—2008年年均叶绿素a与资源丰度表现为较强的正相关。

Abstract: Based on the 2000-2008 squid jigger (Illex argentinus) catch data of Chinese vessels in Southwest Atlantic Ocean and the related environmental information derived from satellites, this paper analyzed the recent 9 years change of I. argentinus resource abundance and its relations to the main ecological factors sea surface temperature (SST) and chlorophyll-a concentration (Chl-a)  in the Ocean. In the recent 9 years, the mean annual I. argentinus resource abundance in the Ocean changed greatly, with a turning point in 2004, i.e., decreased before 2004 and increased after 2004. In the nine years from 2000 to 2008, the SST and Chl-a  in the Ocean had definite correlations with the changes of the I. argentinus resource abundance. In 2000-2003, the annual SST had a larger fluctuation while the mean annual I. argentinus resource abundance was relatively constant, no obvious correlations between them. From 2004 to 2008, there existed a negative correlation between the resource abundance and SST. In 2000-2004, the I. argentinus resource abundance had no obvious correlation with the Chl-a . From 2005 to 2008, a positive correlation was observed between the resource abundance and the Chl-a.
