Several species of tuna that are seasonally common in the waters off New Jersey are very popular with seafood lovers. The bluefin (Thunnus thynnus). the bigeye (T. obesus) and the yellowfin (T. albacares) all supply a large, worldwide market tuna. 

Once available in the U.S. only as a canned product, tuna in the last decade or so has developed a very favorable reputation in domestic markets as a fresh product, often featured in gourmet restaurants. Bluefin tuna, of course, is well-known for supplying the premium sushi market in Japan. 

All of these tunas are large, highly migratory fish. Individuals have been known to span an entire ocean in a season. Like the other oceanic species, little is known of their natural history.
