摘要(Abstract)：

为研究长牡蛎壳黑选育系F7的生长规律,分别采用了线性回归方程和Von Bertalanffy、Gompertz和Logistic 3种非线性模型对长牡蛎(Crassostrea gigas)壳黑选育系F7幼虫期和养成期的生长参数进行生长模型构建,并对长牡蛎壳黑选育系F7养成期的壳高、壳长、壳宽分别与总重进行曲线拟合,以研究长牡蛎壳黑选育系F7的生长规律。研究表明,幼虫期壳高、壳长对日龄的回归方程分别为y=39.723 8+11.697 2x,R~2=0.991;y=31.346 2+9.802 8x,R~2=0.986。壳高与壳长成线性相关,回归方程为y=4.867 0+1.175 0x,R~2=0.989。养成期长牡蛎壳黑选育系F7的总重增长与Von Bertalanffy生长模型最符,R~2=0.955;长牡蛎壳黑选育系F7的总重与壳高、总重与壳长、总重与壳宽分别遵循复合曲线y=0.706×1.055~x,R~2=0.991、y=1.336×1.075~x,R~2=0.983、y=1.287×1.154~x,R~2=0.944。
