My wife loves seafood, but i dont eat it because im allergic 
Seafood is usually composed of fish and shellfish. Are you allergic to both?
Im allergic to shellfish.  I just dont like fish lol
Molluscs, crustaceans, and echinoderms are all types of shellfish and allergies do seem to be quite common. It's a shame you don't like fish it is usually healthy. 
yea, its usually in a lot of diets that I look up, but Ive never like them.  I even hated my pet goldfish when I was younger
Oh no poor fishy. Yeah seafood is an important source of protein in coastal areas around the world.
