ABSTRACT:
A habitat for raising aquatic life such as fish, monitors the temperature and the dissolved oxygen content of the water therein and introduces water from the epilimnion to increase the dissolved oxygen content and the temperature. The habitat is air powered by a low pressure air source which releases air into the habitat to move water during a cyclic operation of a ram-like member. An alternative embodiment can draw cool water from the hypolimnion to mix with warm oxygen-laden epilimnion water, and an embodiment powered by wave action in the open sea is disclosed.
