Unfortunate Prussian carp and crayfish are going to ravage our native fisheries. Maybe sterile European perch would be great to add into a Prussian carp lake.
Fear is Alberta becomes a Prussian carp world.

Technically - you are 100% correct on the rainbow - but that only pertains to the Athabascan subspecies which is isolated in that same (small) watershed (one of the few areas the continental divide was not the "natural barrier" between native and non-native rainbows/steelheads.
But you get my point anyways.
I'm just not a fan of introductions into parts of the watershed that are not geographically/physically disconnected and susceptible to a flood (or some other event) from washing an intended isolated species and introducing it into the entire watershed.
Kinda like stocking dirty flying Asian carp for farming next to river and a natural disaster causes a breach and unintended introduction. Happened in the US and caused the disaster they are dealing with now.
