Most spawning occurred during spring and summer, and moulting occurred mainly after the breeding season but also between spawns.LEARN MORE »

Growing & Harvesting

Breeding activity for redclaw depends on water temperature and day length, and normally occurs between September and April within their natural range. Farmers can protract breeding by providing a controlled environment in which temperature is manipulated to simulate the onset of the breeding season.LEARN MORE »
