<p>The present invention relates to a feeding apparatus installed together with a fish farm to feed cultured fish and, more particularly, to a submersible upward feeding apparatus for aquaculture using a feed bag wherein a feed outlet at the lower end of a feed bag is watertightly mounted into the feed discharge pipe of the bottom surface of a holding case by sinking down the feed bag into the holding case installed on seabed; a feed dispensing pipe including a valve device, a vacuum forming pipe including a pump device and a seawater input pipe including a valve device are connected sequentially from the exit side of the feed discharge pipe; a feed supply pipe is connected to the seawater input pipe to extend to the center of the lower side of a fish farm net; and feed supply into the vacuum forming pipe using difference in pressure after opening the feed outlet using negative pressure and floating feed supply into the fish farm net by seawater supply are enabled to be performed sequentially and repeatedly by each of the valve devices and the pump device by connecting the valve devices and the pump device to a control buoy containing a battery and a control device. Accordingly, uniform growth of cultured fish is promoted by upward distributing feed supply that is the most proper for the feed supply of cultured fish; feed supply by difference in pressure is facilitated by inducing natural contraction of the feed bag by water pressure; and the feed bag can be replaced easily after depletion of stored feed.</p> |
