I have written about pangassius catfish (tra, basa, shark catfish, and what-have-you) before in an article about the trade war caused by protectionist legislators responding to the quick growth and success of the Vietnamese catfish farming industry. However I am doubling back to address the quickly spreading pangassius catfish itself. The farm-raised fish are currently identical to the fish caught in the wild form, but I wonder if that will continue for much longer. Pangasius farming has spread from Vietnam, Laos, and Cambodia to Thailand, Nepal, Pakistan, India, Bangladesh, Myanmar, Indonesia, and, above all, China. I have a feeling that the pangassius catfish will escape in all of these places and establish itself as a successful invader. I also feel like the fish farmers will start pushing the captive fish into new shapes with selective breeding (although the catfish is already a near-perfect farm specimen with its ability to tolerate low Dissolve Oxygen, put on weight quickly, eat anything and survive in fishponds, concrete tanks, fish cages, or fish pens).

Catfish farming never caught on in Nepal. I suppose because Nepalis find catfish distasteful?
There are numerous trout farms in Nepal though, mostly sponsored by the Japanese.

Will catfish eat algae and will they cohabit with goldfish in an outdoor pond
Thank you
