The invention relates to oxygen supply equipment and in particular relates to oxygen supply equipment for aquaculture. Aiming at solving the technical problems, the invention provides the oxygen supply equipment for the aquaculture, which can be used for uniformly dispersing oxygen gas and can be used for enlarging the contact area between water and the oxygen gas. The technical scheme is as follows: the oxygen supply equipment for the aquaculture comprises a first supporting rod, a second supporting rod, a bearing seat, a rotary shaft, a rocking handle, a mounting plate, a transmission wheel,a flat belt and the like; the first supporting rod is placed at the right side in a spraying nozzle; the second supporting rod is placed on the ground; the bearing seat is embedded into the upper part of the second supporting rod; the rotary shaft is connected into the bearing seat the mounting plate is connected onto the rotary shaft. According to the oxygen supply equipment for the aquaculture,the water spraying area can be increased through water which is sprayed out through the spraying nozzle, and the oxygen gas of the water can be increased, so that the oxygen flowing speed of the water can be increased and the oxygen gas can be uniformly dispersed; the oxygen content in the water can be increased through an elastic net and a water wheel, so that a condition that the oxygen contentin one part of the water in a water tank is too high can be prevented, and furthermore, the oxygen content in the water of the aquaculture is effectively ensured.
