The present invention relates to a sea farm provided on land, and the sea farm comprises: a certain volume of a fish tank (100) which is constructed through excavation in the ground, and is formed with an outlet (112) on the bottom while the inner girth thereof forms a circular shape; a water inlet passage (200) which comprises an overground passage (210) that is constructed along the ground while one end thereof is communicated with the sea (S) so that seawater may flow in, an underground passage (220) that is inclined to mutually communicate the lower end of the fish tank (100) and the overground passage (210) and generates a vortex within the fish tank (100) with the flowing power of the discharged seawater by being biased toward the fish tank (100), a first filter (f1) that is provided in the overground passage (210) or the underground passage (220) in order to filter foreign substances out of the seawater flowing from the sea (S), and a second filter (f2) that is provided at the communicated position between the fish tank (100) and the underground passage (220) and prevents marine life from escaping the fish tank (100); a water outlet passage (300) which is constructed along the ground by communicating with the fish tank (100) so that the seawater of the fish tank (100) may be discharged, and includes a third filter (f3) that is provided to prevent the sea life from escaping when filtering foreign substances out of the seawater; and a suction device (500) which includes a suction pipe (510) that is communicated with the outlet (112), and a pumping means that applies suction power so that the deposited foreign substances concentrated on the outlet (112) may be forcibly sucked to the suction pipe (510). |
