I also buy the Sportsman License for my Canadian fishing. It's rare for me to keep anything, but will keep a couple bass for a fish fry on occassion. (I may need it this year when I blow away the field at the OFC pike derby in June ) I also do musky fishing and there have been posts on here as to what constitutes possession and what doesn't. I never intend on keeping any, even if they are of legal size. I'll spend the extra $$, just to be on the safe side.
