Abstract

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± 0.9g and 42.7±1.2g. The realised heritability of harvest weight was 0.24±0.06. Selection did not alter tail dimensions relative to body weight but reduced the age of sexual maturity.
