<P> Pescetarianism / ˌpɛskəˈtɛəriənɪzm / (also spelled pescatarianism) or pesco - vegetarianism is the practice of following a diet that includes fish or other seafood, but not the flesh of other animals . Most pescetarians maintain a lacto - ovo vegetarian diet with the addition of fish and shellfish . </P> <P> "Pescetarian" or "pescatarian" is a neologism formed as a portmanteau of the Italian word pesce ("fish") and the English word "vegetarian". The English pronunciation of both "pescetarian" and "pescatarian" is / ˌpɛskɪˈtɛəriən /, with the same (sk) sound present in pescato (Italian: (peˈskaːto), derived from piscatus, the perfect passive participle of the Latin verb piscor meaning "to fish"), though not in the word pesce (Italian: (ˈpeʃʃe)). </P>
