Crayfish can be farmed in large freshwater ponds, a practice known as aquaculture, for food. The most commonly farmed species are Red Claw Crayfish (Cherax Quadricarinatus) in Southeast Asia and Australia and Red Crayfish (Procambarus clarkii) in America. Aquaculture fields typically are shallow ponds sometimes filled with swamp weeds and grass. The substrate of the pond is mud, preferably with a high clay content to prevent water from draining away.
