Abstract
Abstract Apparatus and method for providing optimum conditions for the growth and maturation of crustaceans during the post-larval period. A series of interconnecting tanks is provided. Habitats are positioned in each growing tank to promote the growth of the post-larval crustaceans, the type of habitat in a tank being provided to accommodate different size animals. The water environment in each tank is continuously changed to remove waste materials from the tank, thereby promoting growth of the crustaceans. The temperature of the water environment is also maintained at an optimum level to further such growth.
