Kalasin's Lam Pao dam has 132 invasive Samchai-area black-chin tilapia recorded (31 Aug-24 Sep 2026), not yet affecting the province's giant freshwater prawn and cage tilapia farms worth about 1.9 billion baht a year. The deputy minister ordered "Find, Report, Catch" (เจอ แจ้ง จับ) campaigns, including QR Code reporting, and teaching farmers to tell black-chin tilapia from Nile tilapia. Provinces may now petition the Fisheries Department for exemptions to normally banned fishing gear. If you farm or buy fish or prawns in Kalasin, Mukdahan-side river basins (Pao-Chi-Mun), watch for the fish, report suspected ones, and check whether local rules on gear have changed before using traps or nets.
