> Hell, a Pacific Chinook will get twice as big as an Atlantic salmon.
They don't have to be bigger and faster, with precise 'local knowledge' to be dangerous to an ecosystem. They merely have to be different.
Perhaps their small size will cause them to escape the attention of normal predators, or their lack of knowledge of what to eat causes them to decimate some species that Pacific salmon don't eat.
