I like a big ol juicy piece of lincod for fish and chips.

I don't have much experience with saltwater, so freshwater in order:
1) Walleye
2) Yellow Perch
3) Bass (Largemouth, probably even Smallmouth but I never caught many)
4) Hybrid Striped Bass - not sure how common these are elsewhere, but they're a sterile hybrid of Striped Bass and White Bass.
5) Channel Catfish
6) Northern Pike. These are tough because of the bones, but you can eliminate a lot of them.
That's a tough call. Freshwater? I live in the Deep South, so I would go with the ironically-named crappie. I understand that as one goes northward, the walleye is the fish of choice. Then we get into trout and other salmonids, but those aren't real freshwater fish.
Saltwater? I like tuna, I like swordfish, even shark. Grouper is the best, though, with flounder running a close second.
