양식방법에 따른 송어 양식업의 경제성 비교 분석

Abstract

Interest in the production of inland fish in domestic demand is increasing. Production volume is low but steady, and among them, the trout fishing industry, which successfully combines the Pyeongchang trout festival and the cage aquaculture, is highly anticipated to develop. The trout farming is carried out by Recirculating Aquaculture System and Running Water System, which have worsened the management conditions due to increased environmental awareness of inland water systems and caused unstable management due to climate change. As an alternative, Recirculating Aquaculture System form method has been highlighted, regulatory compliance cost can be reduced through reduction of environmental load, and form environment can be artificially controlled, so it is relatively insensitive to climate change. From a socio-economic perspective, the management practices of the Recirculating Aquaculture System and Running Water System were compared and the management performance of each type method was compared with the management results of each method through economic analysis to analyse more business-friendly methods. The financial statements of three years and average for each form method were investigated and analyzed. The analysis method was an economic analysis. The 10-year cash flows were analysed for 2015, 2016, 2017 and 3-year averages. The analysis shows that economic analysis of Recirculating Aquaculture System is economically feasible in all three years and on average. The results of the Running Water System show economic feasibility except for 16 years. For 16 years, the price of the oil formula was 500 won lower than that of other years, so the production volume was high, but the total profit was low, so it was found to be not economical. The analysis shows that Recirculating Aquaculture System is more economical than oil, and the Running Water System should stabilize the unit price for business over the long term.
