PURPOSE: A wavelet generator using natural wind is provided to prevent water of a fish farm from becoming turbid, thus improving the environment of fish breeding, and to save a cost of energy by using wind force. CONSTITUTION: A floating body(4) served to float the wavelet generator on the surface of water is installed on the top surface of a fish breeding tank(1) connected to the both side walls of a fishing farm with a wire(5). A trumpet shaped air suction pipe(2) having a wide entrance draws natural wind, and then a propeller type air discharge pipe(6) jets the air through an air discharge hole(9) so as to generate wavelet on the surface of water, thereby a contact time and a contact area between the water and the air can be increased to improve an efficiency of oxygen solution. A bearing is used at a connection part of the air suction pipe and the air discharge pipe so as to ensure the smooth rotation of the pipes provided with a wind indicator(3).
