I did some searching on the forums here and am still a little lost when it comes to these unique fish. I have a few questions that maybe someone on here can help me with. 1.) Can Tiger Trout occur naturally in nature or are they a human created fish? I've heard both sides of this and I would like to have that one cleared up. 2.) Can you only find them on the west side of Washington? I know there are a few places in Central and Eastern Washington that they can be found. 3.) If Tiger Trout inhabit a lake/stream, does this mean that other species of fish is likely going to decline due to the natural predation the Tiger Trout has. Say for instance a Brook Trout lake that is introduced with Tiger Trout, would the Brookies survive or would they get wiped out?
