It was predicted that the maritime industry, including the ones, would become the flagship industry, and aquaculture was expected to become the flagship industry after 2018. In addition, world aquaculture production in 2012 was 67 million tons, an increase of 42% compared to 2006, and the domestic aquaculture industry accounted for 48% of the total fishery industry in 2013. However, in the aquaculture and fisheries industry, the production and supply of aquaculture products has not increased compared to demand because of the deaths caused by diseases that occur on a large scale every year as well as in Korea. This is because aquaculture workers are reluctant to make large-scale investments in aquaculture due to the risk of mortality in aquaculture.

Festival-style farm refers to a method of cultivating fish, etc. while circulating the water after piling up banks on the beach, and circulating the water. Festival-type farm farming refers to the concentration of nutrients due to the continuous administration of feed and excrement of farm animals during fish farming.

At this time, the phytoncide composite composition and NaOCl treated water may be supplied in a weight ratio of 1:2 to 0.5:3. In the above range, it is possible to sterilize and remove external pollutants, and at the same time, it is possible to minimize the impact on aquaculture water and aquaculture environment.

In addition, the NaOCl supply unit 410 is connected through the raw water tank 100 and the supply pipe 408, and can supply NaOCl treated water through the supply pipe 408. For example, before supplying the raw water stored in the raw water tank 100 to the aquaculture tank 200, the NaOCl-treated water is supplied at 2 ppm to 5 ppm through the NaOCl supply unit 410 so that the NaOCl concentration of the raw water is less than 0.5 ppm. Then, sterilized raw water can be supplied to the culture tank.
