Two separate river stocks of Redclaw crayfish (Cherax quadricarinatus) were selected for two generations for increased body weight at 7 months. Averaged over both stocks, mean weights of selected and control lines were 46.7 ± .9g and 42.7 ± 1.2g. The realised heritability of harvest weight was 0.24 ± .06. Selection did not alter tail dimensions relative to body weight but reduced the age of sexual maturity.
