Red claw (Cherax quadricarnatus) is a species of freshwater crayfish native to northwest Queensland and the Northern Territory (Australia). Its physical, biological and commercial attributes make it ideal for aquaculture and its similarity to lobster puts it at the premium end of the seafood sales market. A commercial red claw crayfish enterprise can improve growth rates by applying basic genetic principles. The theory of genetic selection, the practical stages and processes of stock selection and management and the major decision making points are outlined, along with reports of research findings into red claw reproduction. Significant improvements are likely to be made to growth rates of red claw and to the profitability of red claw aquaculture
