Induction of gonadal maturation and egg release using hormones in redclaw crayfish (Cherax quadricarinatus) to facilitate intensive breeding for commercial juvenile production (Old ID 27423)

Australian Society for Fish Biology
Role

Chief Investigator

Description

The commercial expansion of redclaw is hampered by suboptimal methods used to produce fertilised eggs, asynchronous hatching, and mortalities of juveniles that suggest broodstock fertility and nutrition need improvement. The proposed project will investigate induction of gonadal maturation and spawning using hormones in female redclaw. The outcomes of the study are validation and development of strategies to facilitate synchronised mating and spawning of redclaw within hatcheries in preventing suboptimal reproductive performance of redclaw in hatcheries. The established knowledge will help in understanding the hormone induced endocrine control of decapods and facilitate the development of artificial reproduction in intensively managed hatcheries.
