- While their wild populations have plummeted due to overfishing and habitat destruction,researchers estimate there could be over a million captive Mekong giant catfish in Thailand alone.
- Captive breeding presents opportunities for conservation but faces challenges such as maintaining genetic diversity and ensuring traits suitable for survival in the wild.
- Religious beliefs and nostalgia frequently enough play roles in preserving these fish; they’re raised for symbolic purposes as well as commercial interests-one giant barb sold for $52,000 to a fishing park.
- Reintroducing megafish into the wild remains complicated due to environmental pressures like dam construction, illegal fishing, climate change impacts on waterways, and difficulties monitoring large-scale breeding programs.
- Cambodia has seen some signs of recovery of natural populations with successful releases of wild-caught specimens indicating ongoing natural reproduction.
