摘  要：
为获得在工厂化养殖条件下的生长特性和规律,分别对10-14月龄的云纹石斑鱼、七带石斑鱼及其杂交F1 3个群体的体长、体重、生长指标、肥满度、超亲优势率等主要生长参数进行测定、比较和分析,并对3个群体的生长模型进行方程拟合。结果显示,在体长和体长生长指标方面,依次为杂交F1>云纹石斑鱼>七带石斑鱼;10-11、13月龄时,累积体重值依次为杂交F1>七带石斑鱼>云纹石斑鱼,体重和体重生长指标方面,增重依次为云纹石斑鱼>七带石斑鱼>杂交F1;七带石斑鱼的肥满度始终最高,杂交F1次之。研究表明,杂交F1体长生长速度最快,且在11月龄前的体重生长速度最快;云纹石斑鱼在11月龄后体重增长速度加快并超过其他两个群体;每月体长、体重生长值的超亲优势率分析显示,杂交F1在14个月的生长中表现出杂种优势。云纹石斑鱼为等速生长类型,七带石斑鱼与杂交F1同属于异速生长类型。

摘  要：
To study the effects of artificial farming conditions on the growth parameters such as the body length, body weight, growth index, and condition factor, the F1 hybrid of E. moara(♀) × E. septemfasciatus(♂) and its parents at 10 to 14 months old were used for the current study. The optimal growth equations of three groups based on the growth model were established. The results showed that the order of body length and body length growth index from high to low was E. moara(♀) × E. septemfasciatus(♂), E. moara, and E. septemfasciatus, and the hybrid F1 had obvious heterosis in body length. The order of cumulative growth of body weight among 10-11 months and 13 months from high to low was E. moara(♀) × E. septemfasciatus(♂), E. septemfasciatus, and E. moara. The order of body weight and body weight growth index from high to low was E. moara, E. septemfasciatus, and E. moara(♀) × E. septemfasciatus(♂). E. moara had the fastest increment in body weight, and had faster weight growth rate than others after 10 months. The best condition factor was observed in E. septemfasciatus among 10-14 months, and hybrid F1 was the second. E. moara had the lowest degree in the coefficient of variation and the heredity was stable. The current study indicated that the hybrid F1 grew fastest in body length among three groups and grew fastest in body weight before 11 months old, and that the growth of body weight of E. moara was faster than others after 11 months old. Hybrid F1 had a significant heterosis in growth among 14 months. The growth of E. moara was isometric and the growth of E. septemfasciatus was allometric.
