A farming household in An Ngai commune, Long Dien district, Vietnam, has found success in raising grouper, switching from shrimp farming due to disease issues. The household's annual income from grouper farming exceeds 250 million VND. The local Agricultural Extension Center supports the farmers with seed and half of the feeding costs. The grouper farming model, which includes regular water flow and quality control, has proven to be efficient and profitable, with grouper fetching high prices in the market. The local government is encouraging more farmers to adopt this model and will provide preferential loans and improve seed quality management to enhance efficiency.
