Trying to think of some form of regularly served seafood I don't like... there's variations of stuff like coconut shrimp, even though I like shrimp... I don't really like raw oysters much though I love them cooked other ways... but just an item as a whole? I guess calamari. I can eat it, but I don't care for it at all. I'm sure there's other weird shit out there at some fancier places I wouldn't dare order, but as far as run of the mill seafood joints... that's about it as far as I can think of right now.
