摘要: A quantitative genetic analysis was undertaken to estimate the genetic parameters for morphological traits associated with axial growth in Japanese flounder. Three year classes (2009, 2010, 2011) that included a total of 47 full-sib families were produced. At 180 and 360 days of age, six morphological traits that included total length, body length, head length, trunk length, caudal peduncle length and caudal fin length were measured on 1,185-1,981 individuals per year class. Based on these traits observed, fifteen length ratio traits were constructed as well. The phenotypic analysis showed that coefficients of variation for the caudal peduncle length and the ratio of it to other length traits had large variation relative to the other traits analyzed. Genetic variations in axial growth of Japanese flounder were revealed by using a single-trait animal model with the fixed, additive genetic and full-sib family effects. All analyzed traits exhibited moderate to high heritabilities, ranging from 0.33 to 0.80. Heritability was higher at 180 days of age than at 360. The current results for estimating genetic parameters demonstrated that these traits related to axial growth could be improved with family breeding in Japanese flounder.
