摘  要：
本文对人工养殖松江鲈从苗种淡化后进入纯淡水开始至成鱼进入海水育肥准备繁育截止的幼鱼阶段主要生长特征进行了观察研究。养殖期间共测定松江鲈360尾,体长为18.0～145.0mm,体重0.25～45.6g;体长与体重的关系式为W=0.074L2.815(R2=0.973),各个日龄之间幂指数b不尽相同,在60d前b小于3。体长生长速度大于体重生长速度,在165d后b大于3。体重生长速度大于体长生长速度,60～165d时b接近于3,生长接近匀速。适口饵料在60～165d期间出现断档,用人工控制生长的虾苗投喂可保证松江鲈幼鱼正常生长。

摘  要：
This article focused on the growth characteristic of Trachidermus fasciatus farmed in Jiangsu Institute of Marine Fisheries. The period was from fries in pure freshwater to adults released into seawater. The growth parameters for T. fasciatus were measured in 360 individuals with their body length and body weight ranging from 18.0 to 145.0 mm and from 0.25 to 45.6 g respectively. The equation between length and weight was W=0.0074L 2.8588 (R=0.973). The exponent b was different in different stages. It was below 3 before 60 days, which showed that the growth of body length was faster than that of body weight. While it was above 3 after 165 days, which showed that the growth of body weight was faster than that of body length. From 60 days to 165 days, the exponent was around 3 and the growth of length fit to the constant speed type, and they were fed with suitable shrimp during this stage.
