【research content】
　In marine fish farming, water pollutants discharged into the breeding water have a significant impact on the natural hydrosphere, so their removal and effective use are key issues.

　In this study, we used the amberjack grouper, a fish species targeted for marine aquaculture.Epinephelus malabaricusSea asparagus using wastewater discharged from a closed circulation fish farmSalicornia bigeloviiAs a result, it was found that sea asparagus can be grown sufficiently in wastewater from grouper breeding to which the missing elements were added.75%Seawater and100%It was found that it grows well in high-salinity environments such as seawater and absorbs water pollutants well.

　This result represents new insight into material-recycling aquaculture, which simultaneously treats waste and cultivates plants in marine fish farming, and was highly praised by the judges.
