ABSTRACT:
A fish husbandry system which provides for high density raising of fish under controlled conditions. The fish are confined in a plurality of upright, water-filled tanks through which water is conducted in serial flow by conduits. Air or oxygen is introduced into the water in the bottom region of each tank. The flow of water within each tank is from the bottom to the top so that fish waste products are carried upwardly out of the tank and also so that the head of water within the tank assists solution of the oxygen in the water. Waste products, solid and dissolved, are removed from the water as it passes from one tank to the next.
