Original language description
Common carp is one of the leading species in world aquaculture, but selective breeding for growth rate has been given up in this species after unsuccessful selection experiments. We estimated heritability for growth-related traits at 8 weeks of age in Hungarian Synthetic Mirror carp at Vodnany (Czech Republic). Parentage assignment with eight microsatellite markers was used in a 10 dams x 24 sires full factorial cross. Out of 550 offspring, 95.3 % could be assigned to a single parental pair. Animal model heritability estimates were 0.34 # 0.08 for weight and length, and 0.37 # 0.08 for Fulton's condition factor (K). Maternal effects and dominance were not significantly different from zero. The genetic correlation between weight and length was 0.98, andnegative correlations were found between K and length (-0.36) and K and weight (-0.16). It is concluded that selective breeding for increased weight gain can be done in carp, using indirect selection for length. Some limitations of the pr
