PURPOSE: Provided is a red tide damage prevention system being capable of detecting red tide in real time, pumping bottom water to the surface of the sea water to dilute concentration of red tide, thus protecting aquaculture living when the red tide is occurred, and alarming the occurrence of the red time. CONSTITUTION: The system comprises a red tide detecting sensor for detecting a degree of red tide of sea water, a pump driving means for supplying a driving force to a bottom water intake and distribution device when the sensor detects a degree of the red tide is greater than a predetermined degree, the bottom water intake and distribution device(14) for pumping up the bottom water and distributing the bottom water to the surface of the sea water of aquafarms, a light shielding unit(19) for shielding light not to be incident onto the surface of the aquafarms, a light shielding unit operating device for spreading and folding the light shielding unit to open and close the aquafarms, a motor for supplying a driving force to the light shielding unit operating device by being intermitted by a control signal generated from the red tide detecting sensor, and an alarming device(11) for alarming the red tide occurrence.
