A system for breeding marine living comprises a culturing pond (2) and a temperature regulation apparatus by use of water replacement. The apparatus comprises a first closed-cycle heat transfer circuit (7), a heat pump (3) and a second closed-cycle heat transfer circuit (8), all of which are connected in turn in the manner of heat interchange. The apparatus also comprises a seawater supplement pipe (9), a first opened heat transfer circuit (10), a second opened heat transfer circuit (11), a drain pipe (16) and a first by-pass drain pipe (17). A heat exposure side of the first closed-cycle heat transfer circuit (7) is coupled with a supply heat side of a low energy exchanger (4). A supply heat side of the second closed-cycle heat transfer circuit (8) is coupled with a heat exposure side of a high energy exchanger (6). The second opened heat transfer circuit (11) is also connected with a beach earth heat collecting well (1). The system heats or refrigerates supplemental fresh seawater through collecting earth heat or draining the heat of seawater and therefore energy consumption is greatly reduced.
