The Central Administrative Court ruled that the Fisheries Department must keep controlling the spread of the black-chin tilapia under its 2024-2027 action plan, and the Agriculture Ministry must supply resources. The deadline is 180 days from when the case becomes final. The minister has ordered faster action and a detailed plan. Fisheries reports 10.68 million kg removed so far, and 10 provinces show lower density. For fish farmers and traders in affected areas, expect more enforcement, buy-back and processing programmes, and possible restrictions on moving stock. No direct change to business costs is announced yet.
