1. Apparatus for raising aquatic life, and said apparatus positioned in a controlled oxygen and temperature environment within a surrounding body of water, comprising:
- (a) an imperforate containment chamber with depending side walls extending from the surface of the water downward to an elevation below the thermocline;
(b) ram means positioned within said containment chamber and adapted for reciprocatory motion relative to said containment chamber selectively to a first predetermined position and a second predetermined position or a third predetermined position within said containment chamber;
(c) means for imparting relative motion between said chamber and said ram means;
(d) gate means located proximal said second predetermined position and said third predetermined position for passing water between said containment chamber and said surrounding body of water responsive to the position of said ram means.

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.

17. A method for raising aqualife in a controlled oxygen and temperature environment comprising the steps of:
-
(a) placing a vertically oriented containment chamber within a surrounding body of water having a discernible thermocline such that said chamber extends from above the surface of said body of water to beneath said thermocline; (b) placing a quantity of aqualife within said containment chamber; (c) inducing a limited reciprocating motion to a ram-like member mounted within said chamber such that water is selectively discharged from said chamber into said surrounding body of water and drawn into said containment chamber by the action of said ram-like member; and (d) sensing the dissolved oxygen content and temperature of the water within the containment chamber to regulate the rate of reciprocating motion of said ram-like member such that a predetermined oxygen level and temperature are maintained by drawing water into and discharging water from said containment chamber. - View Dependent Claims (18)
