Not sure entirely. I think they study there breeding capabilities, there hardiness, ability to adapt to any environmental conditions, how the feed etc etc.

If they are fast breeding hardy fish that can adapt to any situation and environmentally destructive then they rate them high on the noxious list. Thats my guess.

Cant see why they would let one type in and not the other. Could be because they are rare?
