Aquaculture industries in South Korea’s South Sea, particularly in Gyeongsangnam-do, suffered significant losses due to high water temperatures and red tide advisories. By late August, the cumulative death toll of farmed fish exceeded 3 million, with financial damages estimated at approximately 6.14 billion won. The National Institute of Fisheries Science issued red tide ‘caution’ advisories for waters spanning from Dumyeong to Jisimdo. Local authorities responded by deploying prevention vessels to spray red clay and using drones for monitoring. In response to the crisis, the Ministry of Oceans and Fisheries initiated advance insurance payments to support recovery for farmers in Jeollanam-do and Gyeongsangnam-do. The ministry planned to distribute approximately 900 million won to 39 farms, with goals to expand these payments to 52 farms totaling 2.3 billion won. While the government sought to mitigate the premium burden on farmers, the impact on consumer prices for species such as flatfish and rockfish remained minimal at approximately 0.4%. Recent reports indicate that record-breaking high water temperatures during a summer heatwave have led to even more extensive damage. In Gyeongsangbuk-do, approximately 3.22 million fish died, marking the largest damage on record for that region, with Pohang suffering significant impacts primarily to rockfish stocks. Financial losses in Gyeongsangbuk-do alone are estimated at over 3.3 billion KRW. To address the escalating crisis, the Ministry of Oceans and Fisheries announced a 13.7 billion KRW disaster relief package for 338 affected households across Gyeongnam, Jeonnam, Chungnam, and Gyeongbuk provinces. This package includes direct relief for 67 households facing By mid-year, aquaculture losses have surged sharply, with an estimated 16.2 million farmed fish mortality dead across provinces including Gyeongnam, Gyeongbuk, Jeonnam, and 284 households that conducted emergency releases. Additionally, 49 households will receive financial assistance through interest reductions or loan repayment extensions. The Ministry noted that because Jeju. Suhyup reported 333 insurance claims totaling approximately 25.8 billion won, which is more than double the damage accounts for only 0.4% number and amount of total stock, claims from the impact on consumer prices for flatfish and rockfish remains minimal. previous year.
