Abstract

Provided is a fish farming system whereby fish can be efficiently farmed. A fish farming system comprising a rearing tank (10) in which water supply and discharge, feeding and the discharge of farmed fish (5) are conducted through a pipeline (13) provided at the bottom thereof, a vertically movable feed-discharge unit (50) which drops into the rearing tank (10) for washing or suspending feed residues with the use of a washing brush being driven by a driving motor (65) and provided with a water jet spraying nozzle (62a), and a vertically movable buffer tank (80) which receives the farmed fish (5) in the rearing tank (10) and returns the same due to the spontaneous flow down.

Claims (4)

1. A fish farming system comprising: a water supply and drainage unit; a feeding unit; a rearing tank provided at a bottom portion thereof with a pipeline connected to the water supply and drainage unit and the feeding unit through respective valves so that supply and drainage of water and feeding and discharge of fish or shellfish can be conducted to and from the rearing tank through the first pipeline; a feed-discharge unit configured to be movable vertically, the feed-discharge unit including a brush for washing the inside of the rearing tank, a first driving unit for rotatively driving the brush, and a first nozzle which is arranged in the brush so as to eject water along the rotational direction of the brush, wherein the feed-discharge unit is moved downward to the inside of the rearing tank so as to wash the rearing tank or to suspend feed residues in water in the rearing tank; and a transfer unit configured to be movable vertically, wherein the transfer unit is moved downward for receiving fish or shellfish from the rearing tank until it reaches a position where the fish or shellfish can be transferred by spontaneous falling-flow, and wherein the transfer unit is moved upward for returning the fish or shellfish to the rearing tank until it reaches a position where the fish or shellfish can be transferred by spontaneous falling-flow.

2. The fish farming system according to claim 1, the feed-discharge unit further comprising: a second nozzle for ejecting water to an inner wall surface of the rearing tank, instead of the brush and the first nozzle; and a second driving unit for rotatively driving the nozzle.

3. The fish farming system according to claim 1, wherein a plurality of the rearing tanks are arranged on one straight line and arranged on another straight line perpendicular to the one straight line, and at least one of each adjoining pair of the rearing tanks serves as the transfer unit.

4. The fish farming system according to claim 1, wherein the rearing tanks are arranged so that one rearing tank serves as the transfer unit, and the other rearing tanks are arranged on a concentric circle centered on the one rearing tank.
