Identification & Biology: Ahi refers to two species, bigeye tuna (Thunnus obesus) and yellowfin tuna (Thunnus albacores). In Hawaii, shibi is another name for yellowfin tuna. The Yellowfin gains its name because the soft dorsal and anal fins and finlets are bright yellow in color. The dorsal and anal fins lengthen with age. Yellowfin range from the ocean surface to depths below 100 fathoms. A mature tuna can grow to 6.5 feet and weigh up to 440 pounds.
