The invention discloses a water surface garbage clearing device for aquaculture. The water surface garbage clearing device comprises a water tank, a first filter screen, a second filter screen and a ship body. Floaters are installed at the two ends of the bottom of the ship body correspondingly. Storage batteries are uniformly installed at the middle position of the bottom end in the ship body. Awireless signal receiving and transmitting module is installed on the sides of the storage batteries. A single-chip microcomputer is installed on the other sides of the storage batteries. The output end of the single-chip microcomputer is electrically connected with the input end of the wireless signal receiving and transmitting module through a guide wire. A supporting rod is installed at one endof the top of the ship body through installing angle iron. According to the water surface garbage clearing device for aquaculture, by installing the supporting rod, a solar cell panel is installed atthe top end of the supporting rod, moreover, the storage batteries are uniformly installed in the ship body, by means of the solar cell panel, the device converts luminous energy into electric energyto store the energy in the storage batteries, thus the electric power source is provided for the whole device, and the functions of energy conservation and environment protection of the device are embodied.
