PROBLEM TO BE SOLVED: To provide a circulating-type fishery organism cultivation system for which the amount of replenishing water is brought to a minimum, capable of efficiently removing dust sedimented on the bottom surface of the water tank, of suppressing the occurrence of fishery organism disease despite cultivating the fishery organism in high density, and enabling their flesh quality to be made favorable. SOLUTION: This fishery organism cultivation system includes a plurality of artificial sea algae 36 suspended so that the lower ends thereof reach the bottom surfaces 22a and 22b of a water tank, a wave-making device 32 for generating wave in the water tank, an oxygen feeder 53 for feeding oxygen to the water in the tank, and an underwater belt conveyor 23 for conveying dust including the fishery organism's excreta and dead body and leftovers of baits sedimented on the bottom surfaces of the water tank to a specified site; wherein the bottom surfaces of the water tank are inclined toward the underwater belt conveyor. Besides, the cultivation water tank is collocated with a hydroponic plant where the eutrophicated wastewater in the cultivation water tank is cleaned for reuse. |
