摘要
研究了花尾胡椒鲷幼鱼的最大摄食量与温度和体重的关系。花尾胡椒鲷幼鱼的最大摄食量与体重呈正相关 ,二者的关系为 :Cmax=1 5 95 .3W0 .6 87(Cmax:最大摄食量 ,J/d ;W :体重 ,g)。最大摄食量随温度的变化情况为 :在实验温度为 2 2～ 2 8℃范围内 ,二者呈正相关 ,超过 2 8℃之后呈负相关。最大摄食率与体重的相关关系为 :Rmax=1 5 0 7.6W-0 .313[(Rmax:最大摄食率 ,J/(d·g) ]。采用回归分析 ,建立了由温度和体重预测该种鱼的最大摄食量和最大摄食率的模型 :Cmax=2 86 790e-0 .90 4ln(T3-77.738T2 + 1985 .185T -16 42 9.710 ) W0 .6 16 n =1 6 ,r =0 .994Rmax=0 .887e1.2 6 4ln(-T3+ 78.0 6 1T2 -2 0 0 3.397T + 172 36 .5 2 0 ) W-0 .2 83 n =1 6 ,r=0 .
The maximum food consumption of juvenile threebanded sweetlip is positively correlated to body weight. The regression equation is: C max =1 595.3 W 0.687 ( C max : maximum food consumption, J/d; W : body weight, g). Maximum food consumption is positively correlated to water temperature before 28℃ and is negatively correlated after 28℃. The correlation between the maximum rate of food consumption and body weight can be expressed as follow: R max = 1 507.6 W -0.313 [ R max : maximum rate of food consumption, J/(d·g)]. Two models for prediction of the maximum food consumption and maximum rate of food consumption in the fish based on different body weight and temperature were developed as follows: C max =286 790e -0.904ln( T 3-77.738 T 2+1 985.185 T -16 429.710) W 0.616 n =16, γ =0.994 R max =0.887e 1.264ln (- T 3+78.061 T 2-2 003.397 T +17 236.520) W -0.283 n =16, γ =0.978
