| 摘 要： | 对人工养殖条件下达氏鲟的生长特性进行了研究.通过试验测量数据处理分析,结果表明:平均体重617.27 g,平均全长53.45 cm,平均体长42.38 cm的达氏鲟通过140 d的人工饲养达到平均体重为1379.32 g,平均全长为66.05cm,平均体长为53.55 cm的个体,其全长平均日生长量0.09cm、平均瞬时生长率0.151%,平均日增重量5.443 g、平均瞬时增重率0.574%;全长与体长之间呈线性关系TL=1.1398SL+4.9157,R2=0.9986,体重与全长的关系为WWTL=0.0002TL3.7423,R2=0.9977,体重与体长的关系为WWSL=0.0019SL3.3821,R2=0.9944,幂指数b值均大于3,表明体重在617.27～1379.32 g之闻的达氏鲟在人工养殖条件下生长为异速生长类型,体重生长快于全长和体长生长.
