Pangassius Catfish on a fish farm in Southeast Asia

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).
