On 8 September 2026 the Central Administrative Court ruled that the Fisheries Department and Ministry of Agriculture must complete control of the Nile-tilapia-type "pla mor khang dam" (black-chin tilapia) invasion under the 2024–2027 plan within 180 days. The Interior Ministry must also consider declaring Samut Songkhram a disaster-relief zone within 90 days. If you run a fishing, aquaculture, seafood or farming business in Samut Songkhram or nearby provinces, watch for possible emergency aid eligibility and for tighter enforcement on fish movement and stocking. The ruling does not itself create any payment or new permit rule.
