Blackchin Tilapia Detected in Kalasin’s Lam Pao Dam
Fisheries authorities in Kalasin have launched an inspection after the invasive blackchin tilapia was discovered in the Lam Pao Dam, raising concerns among local fish farmers.
According to a report by Matichon Online on September 10, 2026, fisheries officials in Kalasin Province have initiated an urgent inspection of the Lam Pao Dam following the discovery of blackchin tilapia in the reservoir. This invasive species, which has caused significant ecological disruption in other parts of Thailand, has now reached the northeastern region, alarming local aquaculture operators.
Local fish farmers who manage floating cages in the dam have expressed strong concerns, suggesting that the presence of the fish is likely the result of human activity, specifically the illegal release of the species into the water body. The rapid spread of blackchin tilapia poses a potential threat to the local ecosystem and the livelihoods of those dependent on the dam’s fishing industry.
For residents and travellers, this development highlights a growing environmental challenge in the region. While the immediate impact on recreational activities or local food supplies remains to be fully assessed, the situation is being closely monitored by provincial authorities. It remains to be confirmed how widespread the population of these fish is within the dam and what specific containment measures will be implemented by the Department of Fisheries to prevent further ecological damage. Authorities are currently conducting an 'X-ray' style survey to determine the extent of the infestation.
