| 摘 要： | 根据2001年12月至2002年4月在西南大西洋(57°W—60°W,41°S—47°S)的柔鱼生产资料,对阿根廷滑柔鱼的体长与体重组成,以及体长与体重关系进行分析。结果表明:南渔场(60°W—61°W,45°S—47°S)与北渔场(57°W—58°W,41°S—42°S)柔鱼的优势体长分别为20~21cm与23~24cm,优势体重分别为100~200g与大于400g;体长与体重关系式分别为W=2.7×10-3L3.628与W=4.9×10-2L2.792,并进行了讨论。

| Abstract: | Based on the data of squid fishery of Liaoning Marine Fisheries Group Co.in the Southwest Atlantic from Dec.,2001 to Apr.,2002,length structure,weight structure and the relationship between length and weight were analyzed.The result indicated that in South fishing ground(60°W—61°W,45°S—47°S) and North fishing ground(57°W—58°W,41°S—42°S),the main length group of 1llex argentinus are respectively 20～21cm and 23～24cm;the main weight group of it are respectively 100～200g and >400g;the equation of the relationship between length and weight are respectively W=2.7×10~(-3)L~(3.628) and W=4.9×10~(-2)L~(2.792).And the discussion was made. |
