Cambodia's Mekong Giants Roar Back to Life
23 Jun
Summary
- A national hotline and app transformed scattered rescues into a coordinated effort.
- Conservationists report a striking surge in critically endangered megafish catches.
- Improved communication and trust are key to saving the Mekong's giants.

In Cambodia, a surge in critically endangered megafish has been observed along the Mekong River, a stark contrast to their long-term decline. This revival is largely attributed to a coordinated national effort initiated in late 2025, featuring a national hotline and a dedicated Mekong Fish App.
Conservationists and rapid-response teams have mobilized to rescue and release large fish like the Mekong giant catfish and giant barb. These efforts have transformed what were once scattered incidents into a structured national program. Improved communication and built trust with fishing communities have been crucial, enabling more accurate reporting of these rare catches.
While the numbers are encouraging, many rescued fish are smaller than in past decades, suggesting a younger population. This pattern, however, offers hope, indicating that the species are reproducing. Cambodia's experience provides a cautious lesson that conservation can succeed even in a river system facing intense pressures.
