| 摘 要： | 本文对网箱养殖的2、3龄鸭绿江斑鳜体长和体重进行了测量,并建立体长与体重的回归方程和体长、体重的生长速度方程及加速度方程.结果显示:(1)体长与体重的关系式为W=0.0254L2.9798(82=0.975);(2)网箱养殖斑鳜体长生长拐点为二龄11月份,体重生长拐点为三龄12月份,比体长拐点滞后一整年;(3)网箱养殖的斑鳜极限体重为850.55g,极限体长为33cm,明显小于碧流河水库野生斑鳜的渐近体长和体重.此外,实验结果显示2龄斑鳜网箱养殖的最佳放养密度为28ind/m3.

| Abstract: | The body length and weight of Siniperca scherzeri Steindachner(tow-and three-year old) cultured in cage were measured in this paper.Regressive equation,growth rate equation and accelreation equation based on the body length and weight were also obtained.The main conclusions of the paper were as follows:(1) The relationship between the body weight(W) and body length(L) is W=0.0254L2.9798(R2=0.975);(2) The turning points of body length and body weight are the age of 2 years 11 months and 3 years 12months,resp... |
