That is a Mekong giant catfish, a large, herbivorous catfish native to the Mekong river watershed. With over 80% of their population since 1990 gone, this already rare fish is on the brink of extinction due to overfishing, habitat lose and pollution. Well I do believe it is terribly sad to see such a rare and magnificent animal killed, I find it even sadder how we live in a world where people are forced to do whatever they possibly can just to feed themselves, well there are people who have more money than what could be spent in a hundred lifetimes.
