- Abstract
Heritabilities and genetic and phenotypic correlations were estimated for body weight ( BW), body length ( BL), carapace length ( CL), carapace width ( CW) and carapace height ( CH) of the Penaeus monodon from measurements on progeny at 6 months of age resulting from a nested mating design. Estimation was made on data from 41 full-sib and 10 half-sib families. The estimated heritabilities for these traits were 0.13-0.24, and the significantly phenotypic and genetic correlations were 0.81-0.94 and 0.88-1.00, respectively. The present results indicate that genetic improvement through selective breeding conducted on P. monodon might be feasible and would be an efficient method to obtain a positive response to selection.
