This project examined ways of overcoming a number of barriers that are holding back development and expansion of the redclaw freshwater crayfish industry in coastal Qld and northern NSW. The outcomes from this project will assist the industry to move from a wild harvest to successful aquaculture-based industry.
The project investigated disinfection strategies for egg harvest and identified bacterial pathogens responsible for early mortalities. Control measures included the use of bacteriophage therapy.
Feeding, environment and habitat modifications to improve viability of larval stages and early growth of craylings were examined. The project also identified 2 new viruses associated with adult mortalities following handling stresses.
