DESCRn>TIOU OF SPECIES 01 TOM AM) TUHALIEE FISHES 



The tunas are one of the world's leading fishery resources. They sure 

 widely distributed in temperate, semi-tropical and tropical waters, pr\r\ 

 althoiigh they have heen fished for many centuries off Europe, northern Africa, 

 and Asia, arid mora recently in the Western Hemisphere and the mid-Pacific, 

 comparatively little is known concerning them. Preliminary research indicates 

 that there may he large populations of tima in the mid-Pacific and in other 

 areas that are not now fished, and it is possible that they are one of the 

 world i^B great food reser9'es. 



It is generally considered that five species of tuna, which may be canned 

 and sold as tuna, are landed in the United States. On the Pacific doast the 

 catch includes albacore (Ger/no alnlunga ^, bluefin ( Thunnus thvnnus). skipjack 

 ( Katsuw onus pel§m-j[.s) axid yellowfin ( Neothunnus macropterus ) , while bluefin and 

 little tuna (&ith! y:r]na.a alleteratus ) are taken on the Atlantic Coast. Blackfin 

 tuna (EfiiailUiiUlua SdlMkitlU&&) have been caught in the Gulf of Mexico but not in 

 commercial quantities by United States fishermen. The big-eyed t\ina (Para- 

 thunnus £iM.) is takan in Hawaii and it is reported that occasionally catches 

 of this species are taken by California f ishermaa . Howe?er, since the fish
