Problem to be solved: to provide a fish and shellfish farming apparatus capable of raising a large amount of fish and shellfish in high density by raising water flow in the water by small power.Solution: in the fish tank which circulates the feeding water of the fish farms 2a and 2B, a flow generating device 3 for causing a minimum water level rise is provided in the fish farms 2a and 2B, and the water level is generated in the feeding water by the rising water level and circulated.Diagram【課題】小さな動力で飼養水に水流を生起させて、大量の魚介類を高密度で飼養することができる魚介類養殖装置を提供する。【解決手段】養魚槽2A、2Bの飼養水を循環させるようにした養魚槽において、養魚槽2A、2Bに、最小限の水位上昇をもたらす起流装置3を配設し、上昇水位により飼養水に平面的な水流を生起させて循環させるようにした。【選択図】図1
