PROBLEM TO BE SOLVED: To provide a method for producing algae, capable of increasing a culturing efficiency, sufficiently absorbing carbon dioxide into a culturing medium and avoiding the destruction of the algae. SOLUTION: The method for producing algae related to a method for growing the algae by irradiating it with sun light to the algae cultured in a flat surface type culturing pond 1, is provided by circulating a culturing liquid 2 containing the algae between a three dimensional culturing tank 3 installed next to the culturing pond 1 and the culturing pond 1, harvesting the grown algae by filtering it through at least one kind of a filter 5 and returning the filtrate liquid containing not grown algae for recirculation. |
