Cage culture can also be practiced in swampy areas. The may be constructed like rectangular boxes, bamboo cylinders or anything which can contain fish and when placed in water current, water can pass through it. Cages can also be made using materials such as wire mesh, nylon mesh and wood. The cages must be anchored securely in the water so that they do not get carried away.
