西南大西洋阿根廷滑柔鱼的资源丰度及其与主要生态因子的关系
Illex argentinus resource abundance and its relations to the main ecological factors in Southwest Atlantic Ocean
摘要
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.关键词
