The impacts of rearing and stocking non-native fish into watersheds where they don’t belong are well understood: undue competition for limited resources, hybridization, predation — the list goes on. In the American West, we’ve seen how introduced brook trout outcompete native cutthroat trout and eventually take over; or how rainbow trout mingle with native cutthroat trout during the spring spawn and produce a fertile hybrid that slowly eats away at native fish genetics.
