Pescetarianism or pescatarianism (both spellings are accepted) is the practice of a diet that includes seafood and excludes other animals. In addition to fish and/or shellfish, a pescetarian diet typically includes some or all of vegetables, fruit, nuts, grains, beans, eggs and dairy. The Merriam-Webster dictionary dates the origin of the term "pescetarian" to 1993 and defines it to mean: "one whose diet includes fish but no meat."
