对443尾长鳍吻鮈标本作了年龄和生长研究。用鳞片鉴定年龄并退算鱼的生长.得出体长与鳞径、体长与体重的相关式及生长方程。体重生长拐点在2.2龄。限制捕捞3龄以下个体,有利于资源增殖.
The age and growth of 443 long-finned iguanas were studied. Identify the age of the scales and retired fish growth. Obtained body length and scale, body length and weight of the correlation equation and growth equation. Weight growth inflection point at 2.2 years old. Restrictions fishing individuals below the age of 3, is conducive to resource proliferation.
