摘    要:以2009年1—4月中国鱿钓船在西南大西洋公海生产期间连续采集的阿根廷滑柔鱼Illex argentinus为样本(6 094尾),对其生物学特性进行初步分析。结果表明:渔获物胴长为148~307 mm,优势胴长为200~260 mm,占总数的86.5%;体重为76~586 g,优势体重为150~300 g,占总数的78.7%,判定该渔获物主要来自南巴塔哥尼亚种群;胴长(L)与体重(W)的关系式为W=1.2×10^-4L^2.6779;渔汛期间,胴长、体重与时间之间均符合指数方程模式,分别为Lt=207.54e^0.0013t和Wt=181.52e^0.0046t;阿根廷滑柔鱼性成熟度以Ⅱ期为主,占总数的56.8%,初次性成熟的胴长为244.7 mm;摄食等级以2级为主,占总数的52.0%。

关 键 词:阿根廷滑柔鱼  生物学特性  西南大西洋

Abstract:The biological characteristics of squid Illex argentinus were studied in about 6094 samples collected from Chinese squid jigging vessels in the high sea waters of Southwest Atlantic from January to April in 2009.The results showed that the squid mantle length was found to be ranged from 148 to 307 mm with dominant size between 200 mm and 260 mm,accounting for 86.5% of the total number,and body weight from 76 to 586 g with majority of 150-300 g(78.7%).The relationship between mantle length and weight was exp...
