The amount of algae in public water area rapidly increases when the rainy season is overlapped after the winter season by the increase in temperatures, and causes a lot of damage to the cultivation of marine products. Various ways are provided to solve the said problem, but the present invention fundamentally changes the nutrient salts and the condition of the water temperature for controlling the growth of algae. [Reference numerals] (1) Low water temperature unit; (2) High water temperature unit; (3) High nutrient salt unit; (4) Low nutrient salt unit; (AA) Circulation device in a thermocline layer section; (BB) Water level; (CC) Mutually flexible transfer device when the water temperature at the upper part and the lower part is changed; (DD) Mutually flexible transfer device in case the concentration distribution of the nutrient salt is greater; (EE) l=water layer section |
