<p>The present invention relates to an apparatus for increasing dissolved oxygen in a fish farm, which comprises a vessel that floats on the fish farm for farming aquatic organisms; a fluid conduit installed on the vessel part sunk under the water surface to be connected to the outside along the longitude direction of the vessel so as to generate a propelling force to the vessel by flow of the culture water of the fish farm, and having the inner diameter of the central part smaller than the inner diameter of the extended part extended toward the outside of the vessel escaped from the central part; an air introduction pipe connected to the fluid conduit in the central part of the fluid conduit and extended to the outside of the vessel so as to introduce the outside air by the suction force generated by flow of the culture water of the fluid conduit; and a pump installed on the fluid conduit and pumping the culture water so as to circulate the culture water filled in the fish farm through the fluid conduit. According to the apparatus for increasing dissolved oxygen in a fish farm, the outside air can be introduced into a fish farm while rotating the vessel by the propelling force generated in the suction process of the fluid.</p> |
