Growth traits, largely determined by muscle growth, are the most critical economic traits in shrimp breeding. Myostatin ( Mstn ) is a conserved inhibitor of muscle growth in vertebrates, but until now solid evidence supporting a similar function of  Mstn  in invertebrates has been lacking. In the present study, we examined the  Mstn  expression along with growth trait data in a  Fenneropenaeus chinensis  population, to establish a potential correlation between  Mstn  and growth. The heritabilities of  FcMstn  expression, body weight at 190 days of culture, body weight and length at 230 days of culture, and average daily gain were estimated using 773 individuals and a thirteen-generation pedigree. The results showed  FcMstn  expression was negatively correlated with the growth traits, and the mean  FcMstn  expression in females was significantly lower than that of males, indicating  Mstn  negatively regulates muscle growth in shrimp, and its lower expression may underscore the faster growth of females. Low heritabilities were detected for  FcMstn  expression, suggesting that the expression of  Mstn  might be heritable in shrimp. These results provide strong support for a growth inhibitory function of  Mstn  in  F. chinensis , and suggest a potential method for selective breeding of this species without substantial experimental resources and labor force.
