Intensification of the redclaw crayfish (Cherax quadricarinatus) industry: the importance of sperm quality and male fertility to productivity. (Old ID 27082)
Role
Chief Investigator
Description
Expansion of the redclaw aquaculture industry is limited by suboptimal methods to produce fertilized eggs and craylings for pond production. Improvement of reproductive efficiency is dependent on several factors as well as understanding the underlying causes of subfertility. This project seeks to develop advanced reproductive technologies to characterise sperm quality; establish optimal diets; and develop artificial fertilization and sperm cryopreservation techniques for superior male broodstock to accelerate selective breeding.
