Seafood that smells is not fresh enough seafood.
That said, I'm gross, and I LOVE the smell of butchers and seafood shops. I even like the smell of fishy catfood when you open the tin. I also like the look of raw meat - like a nice red steak or a pink chicken breast... I think it looks really nice, and looks ugly when cooked. Would never dream of eating either uncooked though. Ew.
