摘要： The purpose of the present study is to reveal the effects of different dietary levels of fish meal protein on body weight and survival of Penaeus monodon families. In this study, 5400 P. monodon from 36 families were mixed cultureed with two kinds of different dietary levels of fish meal protein (Diet A and Diet B) for 56 days to analyze the genetic parameters of body weight and survival traits, as well as the interaction effect of genotype and environment. The results showed that the average body weight and survival rate of P. monodon in Diet A group were higher than those of Diet B group, and the heritability of P. monodon in Diet A and Diet B group was 0.53 +/- 0.12 and 0.39 +/- 0.09, respectively, which belonged to high heritability, and the heritability of survival after transformation was 0.38 and 0.22, respectively, which varied from medium to high heritability. The estimated heritability of body weight and transformed survival were 0.46 +/- 0.10 and 0.32, respectively, which showed high heritability level. The estimates of genetic parameters might be overestimated because the common environmental effect was not included in the estimation model due to convergence problem. The results showed that there was a high genetic correlation (0.84-0.92) between Diet A and Diet B groups, and the ratio of GxE variance component to additive genetic variance component was less than 0.5, and the effect of GxE was not significant. The results showed that although the growth and survival traits of P. monodon were different under different diets, the interaction effect between genotype and feed conditions was not significant. Therefore, it was not necessary to establish different breeding lines for different feed conditions in the range of 10% -30% protein level of feed fish meal.
