摘　　要：在人工养殖环境条件下，研究了马来西亚吉罗鱼幼鱼（-2月龄）的生长状况，并对其14月龄个体的形态特征参数进行了测定．结果表明：①幼鱼早期生长迅速，日平均增长为0．41mm，体重呈指数生长，日平均增重0．61g；②14月龄幼鱼可量性状特征为全长／体长1．24、体长／体高2．33、体长／头长5．66、体长／尾柄长3．66、体长／眼间距18．64、体长／尾柄高7．00、体高／尾柄高3．01，全长／体长、体长／体高及体长／头长三个参数比值相对稳定．初步揭示了马来西亚吉罗鱼的早期生长规律和种质特征，为该鱼的规模化养殖和育种工作提供基础数据．The growth regulation and morphometric characters of Tor tambroides juvenile （about 2 months） were studied under artificial condition in the current research. The results showed as followed： @ The growth rates of juveniles were high, with the daily average growth of body length of 0.41 mm, and the daily average growth of body weight, which showed index relationship, was 0. 61 g. @ Measurable parameters ratios of T. tambroides were T1/S1 = 1.24, S1/H = 2.33, S1/Lmx = 5.66, S1/Lpc = 3.66, S1/Io = 18.64, S1/Hpc = 7. 00, H/Hpc = 3.01, Lpc/Hpc = 1.91. The growth regulation and germplasm of T. tambroides juvenile under study will provide basic information for the large -scaled farming and breeding of T. tambroides.
