Characteristics of environments supporting self-sustaining populations
Recently, Mekong giant catfish have been released into rivers and reservoirs throughout Thailand and
Cambodia. There are reports of the Mekong giant catfish being caught in reservoirs every year, with
body weights exceeding 100 kg. This indicates that the Mekong giant catfish can grow to their normal
size in reservoirs. However, to date none of the fish caught in the reservoirs had mature gonads.
