Mekong Giant Catfish: A 646lb River Monster
8 Apr
Summary
- A 646-pound Mekong giant catfish was caught in 2005.
- Adults can grow up to 10 feet long and over 600 pounds.
- The species is critically endangered due to multiple threats.
In 2005, a Mekong giant catfish of immense size, weighing approximately 646 pounds and measuring about 9 feet long, was caught near the Thailand-Laos border. This remarkable catch highlighted the potential size of these freshwater giants and underscored the precarious future they face. Scientists have classified the Mekong giant catfish as critically endangered as of 2026.
These fish, capable of reaching up to 10 feet in length and exceeding 600 pounds, are increasingly rare. Adult specimens typically weigh between 330 and 440 pounds. Despite their size, they are herbivores, feeding on algae and detritus, and lose their teeth as they mature.
Human activities, including overfishing, dam construction, habitat degradation, and pollution, pose significant threats. Climate change also exacerbates these challenges. Conservation initiatives, such as protected zones, fishing bans, and captive-breeding programs, are underway to prevent the complete disappearance of this species.
