Black-Chinned Tilapia Invasion Reaches Lam Pao Dam
Experts warn of a potential ecological crisis as the invasive black-chinned tilapia is confirmed in Kalasin's Lam Pao Dam, raising concerns about the Mekong River basin.
On September 10, 2026, fisheries experts meeting at Kalasin University identified a critical environmental threat: the presence of the invasive black-chinned tilapia in the Lam Pao Dam, Kalasin province. According to Khaosod Online, this species, which has already caused significant ecological and economic damage in Samut Songkhram and southern Thailand, is now considered a national crisis.
Assistant Professor Dr. Chainarong Sretthachau of Mahasarakham University highlighted the severity of this development, noting that the dam serves as a vital connection to the Mekong River basin, which supports over 60 million people. The species is particularly dangerous due to its dual role as a predator and a prolific breeder, capable of thriving in shallow waters where native predators cannot reach them.
Dr. Chainarong emphasized that the fish could not have reached the dam naturally due to the river's many barriers, suggesting human intervention—either through contaminated fish stock or intentional release—is the cause. For residents and travelers, this situation signals a potential shift in local aquatic biodiversity. While the immediate impact on tourism or daily life remains to be fully assessed, the spread of this invasive species poses a long-term risk to the regional ecosystem. Authorities are currently monitoring the situation to determine the extent of the infestation and potential containment strategies.
