Intensive Breeding Potential of Redclaw Crayfish, Cherax quadricarinatus: Evaluation and Improvements of Egg and Embryo Quality, and In Vitro Fertilization Perspectives (Old ID 27486)

Chief Investigator

The commercial expansion of redclaw is hampered by suboptimal methods used to produce fertilised eggs, asynchronous hatching, and mortalities of juveniles. This project seeks to characterise female broodstock fertility and improve hatchery productivity by developing tools to assess egg and embryo quality, induce gonadal maturation and egg release using dietary supplementation and hormonal treatments and by establishing artificial fertilization techniques. The study outcomes include validation of tools to select for egg quality and to develop strategies to facilitate synchronised spawning of redclaw within hatcheries to enhance reproductive performance and facilitate intensification of production.
