The heritability, genetic and phenotypic correlations were estimated for body weight, standard length, body height and body thickness measurements of 10 and 18 month old fish.
Analyses were performed on a total of 41 and 104 full-sib families of grass carp including 937 and 2454 individuals at 10 (first spring) and 18 months (second winter) of age, respectively.
The families were reconstructed using the molecular pedigree based on twelve microsatellite loci, and 97.6% of the offspring were unambiguously assigned to single parent pairs
