The present invention relates to a fish farming tank for removing sludge and more specifically to a fish farming tank for removing sludge having a cleaner installed outside the tank and a central pole installed other than the inside the tank, and thus the circulation of water therein is not disturbed and the tank facilitates the removal of sludge including waste generated during fish farming as the same separates the sludge from fish. In the case that the central pole is mounted in the central portion of the tank, the central pole is perforated finely to prevent fish from moving through, and the circulation of water therein is not disturbed. A corrugated pipe is mounted on a central portion of a first pipe connecting the tank to the cleaner, and thus the height of the first pipe can be adjusted so that the fish farming tank for removing sludge can provide a user with convenience in use. The corrugated pipe is connected to the first pipe mounted on one side of the bottom portion of the cleaner and allowing dead fish to pass through. The cleaner has a perforated plate formed on an upper end surface thereof and a second pipe connected to a filtration tank provided on the other side of the bottom portion of the cleaner to allow sludge to pass through. Thus, the tank prevents fish from moving to the filtration tank and filters the sludge in the filtration tank. An electric device is installed on the central pole or a lower side of the central portion of the tank to provide an electric shock to fish when farming water flows so that weak fish can move to the cleaner and strong fish can remain in the tank. A third pipe is connected to the lower surface of the central portion of the tank using a socket to make shipping and screening of fish easy.;COPYRIGHT KIPO 2016
