QTL with genome-wide significance are presented. “*”, P < 0.05; “**”, P < 0.01; “***”, P < 0.001. PVE: the proportion of phenotypic variance explained. M-BW, M-TL and M-SL represent the body weight, total length and standard length of male; F-BW, F-TL and F-SL represent the body weight, total length and standard length of female; BW, TL and SL represent the body weight, total length and standard length of all fish, respectively.
