Wild Pangasius Mekong Catfish and River Dam Welfare

How Mekong River dams are blocking catfish migration and causing welfare and conservation harm to giant river fish.

Key Facts

The Mekong giant catfish is critically endangered — fewer than a few hundred individuals may remain
Dam construction on the Mekong has blocked migration routes that giant catfish depend on for reproduction
Mekong River dams affect over 70 million people and countless fish species through altered flood cycles
Fish passage infrastructure on Mekong dams is largely absent — fish cannot bypass the barriers
The welfare of giant catfish involves acute suffering during stranding events caused by altered water levels

Welfare Considerations

Mekong giant catfish welfare represents one of the most acute fish conservation crises on Earth. These magnificent fish — the largest freshwater fish in the world — are critically endangered from overfishing and dam construction that blocks migration routes they have used for millennia. The welfare harm occurs through population fragmentation preventing reproduction, stranding events from altered water levels, and the acute suffering of individual fish caught in fisheries. Dam construction decisions rarely include wildlife welfare assessment, treating fish as an externality of energy development. Advocacy for fish passage infrastructure and flow management protocols in dam operations could meaningfully improve outcomes.
