The article explores the impact of global events, such as the Ukraine conflict and rising oil prices, on the production and consumption of flatfish sashimi in South Korea. Located in Jeju Island, the article visits a fish farm, 'Happy Flatfish', that raises flatfish and supplies them to large marts like E-Mart. The farm uses a unique water circulation system and relies heavily on electricity and oil for feed production and water pumping, leading to significant cost increases. The article also discusses the challenges faced by the aquaculture industry, including labor shortages, increased feed costs, and transportation issues, which are driving up the price of flatfish. These challenges are further compounded by the reduction in fishing boats and the supply chain disruptions, with the price of flatfish sashimi rising from 8,000 won per kg in 2019 to 16,000 won per kg in 2021. The article highlights the difficulties faced by sushi restaurant owners in managing costs and maintaining consumer satisfaction amidst these price increases.
