Blackchin Tilapia Outbreak Reaches Songkhla’s Samrong Canal
Authorities in Songkhla are working to contain an outbreak of the invasive blackchin tilapia in Samrong Canal to prevent further ecological damage.
According to a report by Khaosod Online on October 28, 2026, the invasive blackchin tilapia has been detected in Samrong Canal, located in the Mueang Songkhla district. This development has prompted local officials to launch immediate containment efforts to prevent the species from spreading into the Gulf of Thailand, which could severely impact local aquatic ecosystems and artisanal fishing industries.
This invasive species was first identified in the Ranot district in 2024. Subsequent sightings were reported in Sathing Phra district in late 2025 and in Singhanakhon district. The recent discovery in Samrong Canal, specifically in Moo 3 of Khao Rup Chang sub-district, marks a concerning progression of the infestation. Deputy Governor Sangkhom Koetko has initiated a community-led effort to clear the canal and mitigate the spread.
For residents and visitors, this situation highlights ongoing environmental challenges in the region. While the fish are not considered a direct threat to human health, the ecological disruption they cause can affect local food sources and water quality. It remains to be confirmed how effective these containment measures will be in preventing the fish from reaching the open sea and whether the infestation will continue to migrate to other connected waterways in the province.
