A pescatarian is someone who eats fish and usually other seafood, plus plants, but not meat from land animals — no beef, pork, or chicken. Eggs and dairy are a grey edge: some pescatarians eat them, some do not. People argue about the edges the same way they argue about vegetarian. The word was built to sit next to vegetarian, with “fish” in the first part. You will also see the spelling pescetarian; it is the same diet. In everyday talk, many people never use the label at all — they just say they eat fish but not meat. It is not vegan (vegans eat no animal foods, including fish) and not vegetarian in the strict sense (vegetarians do not eat fish).
