Mass Fish Die-Off Reported on Koh Libong, Trang Province
A significant number of dead fish have washed ashore on Koh Libong, causing concern among locals, though experts suggest environmental factors rather than seismic activity.
On October 20, 2026, reports emerged of a large number of dead fish, including grouper and parrotfish, washing up along the Ban Lang Khao beach on Koh Libong, the largest island in Trang province. According to Khaosod Online, the fish have been dead for approximately two days, resulting in a strong odor in the area. No official cleanup efforts have been initiated as of yet.
Local tourism operator Jittapol Tananusorn stated that the phenomenon appears to be localized to Koh Libong. He attributed the die-off to a sudden change in sea temperatures, potentially linked to La Niña conditions, rather than any seismic event. While some residents have expressed fears regarding a potential tsunami, experts emphasize that there is no evidence to support such concerns and have urged the public to remain calm.
For travelers and residents, the situation is primarily an environmental concern. The island previously experienced coral bleaching in May 2026 due to global warming, though the ecosystem had shown signs of recovery before this recent incident. It remains to be confirmed whether official environmental agencies will conduct a formal investigation into the water quality or the specific cause of the mortality. Visitors to the area should be aware of the current conditions along the beach and are advised to follow updates from local authorities.
