Molting, reproductive biology, and hatchery management of redclaw crayfish Cherax quadricarinatus (von Martens 1868)

Commercial crustacean fisheries are dwindling while demand is growing. Aquaculture is expected to meet supply requirements, thus better egg production and hatchery management are required if the industry is to keep growing. In addition to hatchery management, methods that improve crustacean juvenile production by manipulating their endocrine system are being assessed. Redclaw Cherax quadricarinatus aquaculture technology is mature enough to grow into an important industry. However, further growth requires research on nutrition, disease and reproduction. The present manuscript reviews existing literature about redclaw reproduction, hatchery, and nursery technology. Further research is bound to improve monosex larval production or at least develop methods to improve growth in both sexes. The market for redclaw is growing, aquaculture in warm countries is increasing and research is improving aquaculture methodologies of the species. The future is bright.
