| 摘 要： | 跟踪测定9个雌核发育牙鲆Paralichthys olivaceus家系后裔150、240、360 d时的生长资料,对体重、体长、绝对增重率、绝对增长率和体型指数（头长/体长、尾柄长/尾柄高）进行方差分析,对体重和体型指数进行相关分析,并建立了体重-体长的回归方程。结果表明：家系C11847的体重、体长及头长/体长与尾柄长/尾柄高指标在各阶段均有明显的生长优势,可作为重点家系加强选育。不同生长阶段绝对增重率和绝对增长率最优家系不一致,且家系间的生长差异主要发生在240 d前。各日龄体型指数均与体重呈极显著负表型相关（P〈0.01）。不同日龄体型指数间差异显著（P〈0.05）。雌核发育牙鲆的体重与体长之间呈曲线相关关系,且该关系在不同日龄间无显著差异（P〉0.05）。

| Abstract: | Growth was measured at 150,240 and 360 days after hatching among 9 families of gynogenetic Japamese flounder Paralichthys olivaceus.Variance analysis of the body weight(W),body length(L),absolute growth rate in body weight(AGRw),absolute growth rate in body length(AGRl),the proportion of head length to body length(LH/L) and the proportion of caudal peduncle length to caudal peduncle depth(LCP/DCP) were conducted,and regression equation of W and L were established.It was found that the fish in family C11847 ... |
