Thanh Hoa and Dak Lak provinces in Vietnam are developing fish farming in reservoirs for water storage, flood prevention, electricity generation, irrigation, and aquaculture. Thanh Hoa has over 610 reservoirs, including two national ones, and is focusing on intensive cage fish farming, while Dak Lak has over 42,000 hectares of water surface area for aquaculture but faces licensing challenges. The Department of Agriculture and Rural Development of Dak Lak is pursuing a production chain-based approach, high-tech aquaculture, and sustainable practices, and has proposed simplifying permit procedures for aquaculture. The People's Committee of Thanh Hoa is developing a cage fish farming project to 2025, with the Department of Agriculture and Rural Development proposing policies to support fish farming in rivers, irrigation reservoirs, and hydropower plants.
