| 摘 要： | 对宁德地区网箱养殖大黄鱼(Pseudosciaena crocea)生长特性进行了研究。测定了780尾大黄鱼25个月龄的各项生长数据,体长变幅为20.5~320.0 mm,体质量变动范围为0.281~555.5 g;生长指标显示,体长生长指标为0.208~2.123,体质量生长指标为0.529~47.579;肥满度波动范围为1.74%~2.37%;肝指数变动范围为0.92%~2.07%;鳔生长指数为1.08%~1.85%;雌鱼性腺成熟系数为0~10.04%,而雄鱼则为0~2.27%。以Keys氏公式W=aLb,拟合25月龄养殖大黄鱼的体长(L)与体质量(W)的关系式为:W=0.0195 L 2.9775(R2=0.9959),其中b≈3,即此生长阶段的网箱养殖大黄鱼生长均匀,为等速生长类型;体质量生长呈幂函数生长,其回归方程为:y=1.8617x1.8099(R2=0.9931)。体长Y(cm)与养殖时间X(月龄)的生长呈二次多项式关系,其回归方程为:y=?0.0259x2+1.7125x+4.1534(R2=0.989)。 |

| Abstract: | The growth parameters for Pseudosciaena crocea of Eastern Fujian stock were measured in 780 individuals in 25 months.Range of the body length or body weight was 20.5-320.0mm or 0.281-555.5g,respectively.The varations of growth indexes for length,weight and fatness in 25 months were 0.208~2.123,0.529~47.579,and 1.74%~2.37%,respectively.Moreover,we found that the index of liver varied from 0.92% to 2.07%,swim bladder weight 1.08% to 1.85%,and gonadosomatic 0 to 10.04%(male: 0~2.27%,female: 0~10.04%).Besides,o... |
