Abstract

Macrobrachium rosenbergii

genetic selection

harvest body weight

heritability

selection response

A breeding programme of giant freshwater prawn Macrobrachium rosenbergii is conducted in Malaysia to improve growth performance. The harvest body weight (HBW) data of 6,159 individuals from 102 sires and 141 dams produced over three generations of selection was analysed using residual maximum-likelihood methodology. This enabled the estimation of variance components and genetic parameters of the studied trait in the population. The heritability (h 2) and common environmental effect (c 2) of HBW were 0.165 + 0.153 and 0.043 + 0.013 respectively. The selection response per generation estimated by comparing the difference in mean breeding value of HBW between generations was 18.01%. It was similar with the average selection response estimated by comparing least square mean (LSM) between generations (17.78%). These results indicated that improvement of the studied trait has been achieved in this population.
