Somewhat related to this topic but more so on rearing other types of fish than just walleye. Looks like Wisconsin puts a little more $$$ into stocking. Or at the very least a variety of species. Just a couple of the top of a quick search:

Those are some big numbers of fish to feed muskies. We probably wouldn't have a enough prey fish left to feed them in AB
I wonder if the Cold Lake fish hatchery is or could be setup to handle pike and perch? I'm asking as I don't know. No doubt it could at least handle minnows and other smaller prey fish.
