Steelhead you are confusing me. A couple posts above you said largemouth wouldn't reproduce in Alberta and now in this post you are saying they would. What is it?

As for bass eating trout, they do everywhere else they coexist so I can't see why Alberta would be any different. In fact, small trout are a major part of the bass' diet in some systems at certain times of the year.

As for bass taking off like perch or taking off like they did in BC, I think you are missing a critical element. Perch are well suited to Alberta's cool waters......largemouth bass aren't. Perhaps we should import some milfoil while we're at it?
