Apparatus and method for rearing fish in an open body of water by confining the fish in floating raceways located in a shallow zone near the water surface and flowing water from a deeper cold water zone through the raceways. An air injection means is supplied for injecting air into the water at the cold water zone to both aerate and pump the water through the system. Vertically adjustable means may be provided to intake water from various cold water depth zones. A floating waste settlement tank may also be provided downstream of the raceways for repurifying the water.
