Approximately 90% of trout farmed in Korea is sold or distributed directly through self-owned restaurants, facilitated by mutual information exchange between farmers. This has allowed the trout farming industry to effectively manage supply and demand, minimizing damage and maintaining stability during the decline in aquaculture product consumption due to the Corona 19 pandemic. Despite this, there is regret for the slow expansion of the industry. The Korean Trout Farming Association is exploring ways to increase utilization rate and income of aquaculture farmers by expanding the market for processing. There is interest in potential cooperation between trout farms and large corporations planning to cultivate salmon in Korea.
