Cambodia marks first year with no Mekong dolphin deaths

Cambodia has reported a remarkable milestone in wildlife conservation: no Mekong Irrawaddy dolphin deaths over the past year. The Ministry of Agriculture, Forestry and Fisheries (MAFF) announced on Saturday that between November 2024 and November 2025, not a single dolphin was lost — the first time this has happened since monitoring began in 2002.

The achievement comes as the critically endangered species, listed on the IUCN Red List, continues to face threats from illegal fishing and habitat degradation. Yet the latest figures show encouraging signs. Seven newborn dolphins were recorded this year, bringing the national population to 111 individuals.

Officials credit the success to coordinated efforts between government agencies, local authorities, WWF, river guards and fishing communities. Fishermen have played a crucial role, sharing information and helping to curb illegal practices along the Mekong.

The numbers build on recent progress: nine births were documented in 2024, the highest in four years, following steady increases in previous years. Conservationists say the dolphins are more than a national symbol; their presence signals healthy rivers and ecosystems that sustain millions of people.

Irrawaddy dolphins (Orcaella brevirostris) are distinctive for their rounded foreheads and short beaks. While the species inhabits coastal waters across South and Southeast Asia, only three freshwater populations remain — in the Mekong (Cambodia/Laos), the Ayeyarwady (Myanmar), and the Mahakam (Indonesia). All three riverine groups are ranked critically endangered.

In the Mekong, the dolphins are confined to a 180 km stretch of river from Kratie Province to just below the Khone Falls in Laos. Their survival is seen as a barometer of river health, with WWF noting that their presence reflects biodiversity and functioning ecosystems that provide vital services for local communities.

For Cambodia, the absence of dolphin deaths over a full year is both a conservation triumph and a sign that sustained cooperation can protect one of the Mekong’s most treasured inhabitants. The challenge now is to maintain momentum and ensure the fragile population continues to grow.
