what do you call a person who only eats fish
Pescetarianism Those on pescetarian or pollotarian diets may define meat only as mammalian flesh and may identify with vegetarianism.[2][3] Most pescetarians maintain a lacto-ovo vegetarian diet with the addition of fish and shellfish, described as "fish but no other meat".[4] The common use association between such diets and vegetarianism has led groups such as the Vegetarian Society to state that diets containing these ingredients are not vegetarian.[5]
