| 摘 要： | 运用Pearson相关分析对尼罗罗非鱼可量性状进行分析,并采用Logistic、Gompertz、Bertallanffy三种非线性模型对尼罗罗非鱼生长相关参数进行生长模型构建,以研究尼罗罗非鱼的生长发育规律。结果表明:尼罗罗非鱼各形态性状与体重之间的相关系数均达到极显著水平(P<0.01),体重与全长、体长、体高的相关性相对显著,与尾柄长的相关性不明显。生长模型研究结果表明:三种模型均能很好地模拟尼罗罗非鱼生长曲线,拟合度(R2)均高于0.983,其中以Logistic模型的拟合度最高(R2=0.991),运用这3种模型对尼罗罗非鱼进行生长曲线的拟合和比较分析较为可行。 |

| Abstract: | In order to study the regular pattern of growth and development in Nile tilapia Oreochromis niloticus, we used the Pearson correlation analysis and three nonlinear models which were Logistic, Gompertz and Bertallanffy to structure the growth model of Nile tilapia. The result showed that the correlation coefficient of Nile tilapia between every morphological traits and body weight had reached a significant level (P<0.01), total length, body length and body height had a high correlation with body weight, but the correlation with caudal peduncle length was not obvious. This study structured three growth models of Nile tilapia which were Logistic, Gompertz and Bertallanffy, respectively. The result showed that this three models could simulate the growth curve well, the goodness of fit (R2) using the three models were higher than 0.983, and the Logistic model (R2=0.991) is highest. Therefore, it is feasible that using these three models to simulate the growth curve of Nile tilapia. This result could increase efficiency of Nile tilapia selective breeding. |
