PURPOSE: A system for removing dissolved ammonia in fish farm is provided to strip dissolved ammonia generated from excretions of fish, and recycle ammonia-stripped water, therefore it can help the growth of fish. CONSTITUTION: In the body (A), a preliminary heat exchange part (10) equipped with a heat exchange (11) therein is installed, in which reservoir water (50) and water circulated from a water tank (30) are heat-exchanged so that the temperature of reservoir water is maintained at 25-30 deg.C. And then, heated reservoir water flows into a primary heat exchange part (20) in which a heat source (40) elevates the temperature of reservoir water up to 40-45 deg.C through a heat-dispersion pipe (21). Finally, reservoir water flows into the water tank (30) in which stripped ammonia gas is blown out by a fan (60), ammonia-stripped reservoir water is drained to reservoir through a weir (31) installed along the outer circumferential part of the water tank.
