I don't know what a shooter is.  I'll ask next fall and I'm sure I can find out.  Walleyes are definitely called pickerel, northerns are "jacks", and I've even heard crappies called "strawberry bass".

If you go to Canada that frequently you should definitely check out two of their TV shows:  Corner Gas and Trailer Park Boys.  Trailer Park Boys is just about the funniest thing I've ever seen, anywhere. Corner Gas is more family oriented, but funny nonetheless.
