Sport Fishing's guide to tunas, arguably the single most important, valuable group of game and food fishes in the world.
By Doug Olander. Sportfishingmag.com
Two groups (sometimes known as “tribes”) dominate the tuna clan. One is Thunnini, which is the group considered true tunas, characterized by two separate dorsal fins and a relatively thick body. The 15 species of Thunnini are albacore, bigeye, black skipjack, blackfin, bluefin (three species: Atlantic, Pacific, southern), bullet, frigate, kawakawa, little tunny, longtail, skipjack, slender and yellowfin.
The other tribe is Sardini; these tunas — the dogtooth tuna and several species of smaller true bonitos — are somewhat more mackerel-like (notably with a more elongated body and a row of sharp, conical teeth).
