The Ministry of Oceans and Fisheries in South Korea has formulated a comprehensive plan, '2021 Comprehensive Measures for Preventing Jellyfish Damage', to mitigate the harm caused by jellyfish in coastal waters. The plan includes predicting the seasonal presence of jellyfish, implementing preventive measures, and providing post-recovery support. The ministry will utilize data from various sources for forecasting and will alert fishermen and local governments. Additionally, the plan includes a rapid response system, repair, and support for damage to aquaculture and fisheries, and first aid and insurance coverage for beach users.
