Abstract

Blunt snout bream (Megalobrama amblycephala) is an herbivorous freshwater fish species native to China and has been recognized as a main aquaculture species in the Chinese freshwater polyculture system with high economic value. The genetic parameter estimates for important economic traits are needed for its selective breeding. The aim of this study was to estimate the heritabilities for its growth‐related traits and explore the genetic and phenotypic correlations among the traits using microsatellite‐based pedigree approach. Offspring from a mass‐spawning of 92 broodstocks (42 sires and 50 dams) were reared in a communal pond and nine microsatellites were used to identify the parents of each..
