Garcia Vazquez S, 2009. Cherax quadricarinatus (known by several common names, including Australian red claw crayfish, Queensland red claw, redclaw, tropical blue crayfish, freshwater blueclaw crayfish) is an Australian freshwater crayfish . A. W. \Reaser, J. K. \Bright, C. \Neville, L. E. \Howard, G. W. \Murphy, S. J. Khalaila et al., 2001, 2002; Shechter et al., 2005). These crosses yielded almost 100% females, a finding that conforms to the above-suggested sex determination model for C. quadricarinatus and the female WZ genotype of intersex individuals. Like many freshwater pest fish, once populations of redclaw have become established, eradication is almost impossible. In Australia, production is 70 tons per annum, with a yield 1000-4000 kg ha-1crop-1. Polypeptides of relatively low molecular masses (65-95 kDa) and of relatively higher molecular masses <100 kDa) were found in the primary-vitellogenic ovary and in the secondary-vitellogenic ovary (and newly laid eggs), respectively. Redclaw from harvest to market: a manual of handling procedures. Two anatomically distinctive types of primary-vitellogenic ovary were shown, one containing milky white oocytes and the other containing two diversely coloured oocyte populations.

On the contrary, since it has the potential to survive low winter temperatures, there is the risk that it will become established, particularly in southern European countries. After harvesting, mostly through the application of flow traps, stock are held in tanks with a flow-through water supply or a recirculating system with biological filtration and maintained in the tank for at least 24 h to permit purging of the gut.
