Haven't had a bad fish yet and I think Atantic is the only one I haven't tried. Like any wild game, putting some care into keeping and cleaning your catch makes a big difference when you go to eat it. Most get released but the best eaters are the small to medium guys.
I like to grill some when it's fresh and unfrozen and use a Foodsaver to freeze the remainder of the day's catch. Once there's a decent supply in the freezer (end of July, maybe?), I'm mostly just Derby fishing. Oh - Muskybob's Adirondack Chowder is insanely good, by-the-way and a great way to use up a pound or two of fillets!
