PROBLEM TO BE SOLVED: To provide a complete recycling (closed circuit) fish and shellfish aquaculture system that suppresses pathogenic bacteria without using ultraviolet light and ozone, in a closed circuit aquaculture, the system that uses microorganisms and thereby achieves a cyclic use of seawater and freshwater.SOLUTION: A complete recycling fish and shellfish aquaculture system is constituted of an aquaculture water tank 7, a mixing layer 1, a fermenter 2, a fermentation synthesis tank 3 and a synthesis tank 4. Use water is pumped from the aquaculture water tank 7 to the mixing layer 1 using a raw water pipe 12. In the mixing layer 1, a fermentation culture solution is mixed with raw water. Then, this water is made to flow through the fermenter 2, the fermentation synthesis tank 3 and the synthesis tank 4, respectively, and is returned to the aquaculture water tank 7 using a treated water transfer pipe 11. Thereby, the water is circulated and used as compound fermentation enzyme water for aquaculture and high energy water.SELECTED DRAWING: Figure 1 |
