I don't think they are.
Most of the rainbow trout in Georgian Bay and in the North Channel come from aquaculture operations. They are escapes, and we have a huge volume of escapes from these operations. What happens, actually, is that mussels grow on the side of the nets, which eventually rip.
It's interesting. There's a study being done now by a researcher, and she's about to publish it, but parts of it were presented at the Great Lakes Fishery Commission conference. What it shows is that along the North Channel the genetic makeup of the rainbow trout is now changing completely to that of escapes. The native wild rainbow are now disappearing. There's a genetic changeover taking place.
This is always the great fear: when you introduce a fish that has only one genetic form, they start to take over. If they do, if something happens, be it weather or disease or whatever, you can lose them all. You lose the diversity you find in wild genetic makeup.
So that's where we would see most of the rainbow within Georgian Bay and the North Channel—they really come from escapes from aquaculture operations.
