池养条件下江黄颡鱼幼鱼的体长生长与时间呈线性关系:L=0.5752t+15.267(r=0.9834);体重生长与时间呈指数关系:W=1.7392e0.014t(r=0.9746);体重与体长关系式为:W=0.0239L1.3658(r=0.9397);幼鱼期水温对体重瞬时生长率作用明显,28.2℃时体重瞬时生长率最大;不同生长阶段生长率差异较大,在60~90日龄体重瞬时生长率最大;幼鱼期个体间生长具有一定的差异性。
There was a linear relationship between body length growth and chronological growth of pond juveniles (L = 0.5752t + 15.267 (r = 0.9834)). Exponential growth was related to time: W = 1.7392e0.014t (r = 0.9746 ); The relationship between body weight and body length was: W = 0.0239L1.3658 (r = 0.9397). The effect of water temperature on body weight instantaneous growth rate was significant at 28.0 ℃. The body weight instantaneous growth rate was the highest at 28.2 ℃. Large, the body weight of 60 to 90 days of age, the largest instantaneous growth rate; juvenile growth of individuals have some differences.
