Feeding apparatus for a marine- aquaculture by submersible and upward feeding type

摘要

The present invention relates to a fodder supplying device installed with a fish culturing holder so as to feed cultured fish. More specifically, while a fodder storing tank for storing a floating-type fodder is settled on the seabed, a fodder feeding pipe and a fodder discharging pipe are respectively connected with the top end and bottom end of the fodder storing tank. At the outlet side of the fodder discharging pipe, a fodder distributing pipe equipped with a valve tool and a vacuum composing pipe equipped with a pump tool are sequentially connected. A seawater feeding pipe equipped with a valve tool is connected with the vacuum composing pipe, and a fodder supplying pipe extended toward the bottom side central part of a holder net is connected with the inlet part of the seawater feeding pipe. The valve tool and pump tool are made to come in contact with a control buoy having a battery and a control tool equipped therein. Accordingly, fodder feeding into the vacuum composing pipe using the pressure difference of the atmospheric pressure and negative pressure and floating-type fodder supplying into the holder net by means of a seawater supply can be sequentially and repeatedly performed by means of the valve tool and pump tool. Bottom-up dispersing-type fodder supplying which is most appropriate when feeding cultured fish is performed, so that the cultured fish can be evenly grown. Moreover, unneeded waste in terms of cost, manpower, and fodder needed for managing feeding can be minimized, and breakdowns and malfunctions of the fodder supplying device caused by waves can be preemptively prevented.
