I absolutely do.
Saskatchewan has all of the normal species for prairie provinces. Our three major fish would be walleye, pike, and perch. We also have lake trout as our only native trout species, but within our fish culture station we also produce 10 other varieties of fish that are populated throughout our province.
Carp is an invasive species in Saskatchewan, but it has suddenly become very attractive for people from Europe to fly over to Saskatchewan to fish for our carp. We're in somewhat of a dilemma. It's a great economic opportunity, but it's also an invasive species that's causing some damage.
There are always changes in the aquatic world.
