Linear Mixed Effects Model and Restricted Maximum Likelihood (REML) were applied to estimate the genetic parameters for growth traits based on sixty-eight full-sib families of the Kuruma shrimp Penaeus . The results indicated that the heritability estimates of body length (BL), abdorminal segment length (ASL), and body weight (BW) were 0.1545±0.0505, 0.1672±0.0473, and 0.1934±0.0439, respectively, on day 45. On day 75, the heritability estimates were 0.1933±0.0475 for body length, 0.1937±0.0468 for abdorminal segment length, and 0.1992±0.037 for body weight, all of which were found to be at moderate levels. Strong positive phenotypic and genetic correlations between growth-related traits at different stages were detected. The phenotypic correlations between BL and ASL, BL and BW, and ASL and BW on day 45 were 0.7121±0.0188, 0.5147±0.0277, and 0.5052±0.0280, respectively, while the genetic correlations were 0.9896±0.0034, 0.9304±0.0321, and 0.9429±0.0301, respectively. The phenotypic correlations between BL and ASL, BL and BW, and ASL and BW on day 75 were 0.6710±0.0236, 0.6555±0.0181, and 0.6534±0.0160, respectively, while the genetic correlations were 0.7637±0.0161, 0.7479±0.0148, and 0.7177±0.0131, respectively. Selection for growth traits in was found to be effective in the present study, and selection for one growth trait can improve other growth traits simultaneously in a breeding program. The results of this study provided reference data for early selective breeding and multi-trait selection of .
