Black-chinned Tilapia Found in Lam Pao Dam, Raising Alien Species Invasion Concerns

The 'black-chinned tilapia' (scientific name: Oreochromis melanotheron), identified as an alien species, has been discovered in Lam Pao Dam, located in Kalasin Province, northeastern Thailand, sparking concerns about its impact on the local ecosystem. According to reports from local media outlet MGR Online, the fish was found with two fishing lures attached to its body when it was captured in the dam. This discovery suggests the potential establishment and further spread of alien species within the dam, prompting heightened vigilance from experts and relevant authorities. The black-chinned tilapia, believed to be native to Africa, is known to adversely affect ecosystems outside its natural habitat through competition with native species, depletion of food resources, and transmission of diseases. Lam Pao Dam is one of Thailand's major reservoirs, supporting the regional economy through agricultural water supply and fishery resources. Therefore, this discovery is a matter of significant concern for local residents and those involved in the fishing industry. Authorities are expected to proceed with investigations to accurately assess the fish's population status and distribution range, and to consider implementing control measures such as eradication if necessary. The invasion of alien species poses a serious threat to Thailand's rich biodiversity and the livelihoods dependent on it, making future developments a subject of keen interest.
