Black-chinned Tilapia Infestation Reported in Ratchaburi Following Floods
Residents in Ratchaburi have discovered significant numbers of invasive black-chinned tilapia in local waterways and orchards following recent flooding.
According to a report by Khaosod Online on October 23, 2026, the receding floodwaters in Ratchaburi province have revealed a widespread presence of the invasive black-chinned tilapia. Local residents in areas such as Sam Ruean sub-district, Mueang district, have reported catching large quantities of these fish in their nets while attempting to fish in flooded canals and orchards.
Dr. Surapol Sinket, a local expert, noted that the recent severe flooding has likely facilitated the rapid spread of the species into rice paddies and agricultural gardens, as the fish are known for their high reproductive rate. Residents have expressed growing concern over the potential for a large-scale infestation that may be difficult to contain, despite ongoing efforts by local authorities to drain water from affected areas.
For residents and visitors, this development highlights a potential ecological shift in local waterways. While the fish are not inherently dangerous to humans, their presence can disrupt local aquatic ecosystems and impact agricultural productivity. It remains to be confirmed how government agencies will adjust their eradication strategies to address the fish's movement into private orchards and smaller irrigation channels. Authorities have not yet issued specific warnings regarding water usage, but the situation is being monitored as a significant environmental challenge for the region.
