The Agriculture Ministry is reviewing a leftover central budget of about 350 million baht to expand the fight against black chin tilapia over a 180-day plan linking 29 agencies. The Fisheries Department reports over 10 million kg removed since February 2024 across 21 provinces, and a new sighting of 41 fish at Lam Pao dam in Kalasin. Key rule for businesses: the fish is a banned alien species; keeping, breeding or moving it alive is illegal. If you farm fish or trade in aquatic stock, check your source and report sightings. Proposed 2027 plan is only 15 million baht, so no direct cost or income change yet.
