~ Yellowfin Tuna, Yellow fin
Tuna, Allison tuna, long fin tunny, longfin, Pacific long-tailed Tuna,
ahi, and Tuna
~ Yellowfin Tuna are
metallic dark blue, almost black along the back, while the belly and
lower sides are silvery white and crossed by many vertical, interrupted
lines. Perhaps most distinctly, a golden stripe runs along
side. The second dorsal and anal fins and finlets are bright yellow, and
the finlets are bordered by a narrow band of black. The yellowfin is a
large tuna. Its body is strongly fusiform (tapered at both ends,
football like) and deepest under its first dorsal fin. Two dorsal fins
are present. In adults, the second dorsal fin is very long, as is the
anal fin, which is directly below the second dorsal. The pectoral fin is
also long, reaching beyond the space between the dorsal fins. The tail
is very slender and v shaped. Seven to ten dorsal and ventral finlets
~ Yellowfin Tuna can grow over 6 feet in length and reach weights of
over 400 pounds. Most angler caught Yellowfin Tuna are under 100 pounds.
~ The Yellowfin Tuna is an epipelagic, oceanic fish, living above and
below the thermocline, at temperatures of 65 to 88°F. It is generally
found in the upper 330 feet of the water column. Yellowfin Tunas are
found worldwide in tropical and subtropical waters, from latitudes of
approximately 40°N to 35°S.
~ The Yellowfin Tuna seem to be opportunistic feeders eating what is
available at the time. Fish species consumed by the Yellowfin Tuna
include dolphinfish, pilchard, anchovy, flyingfish, mackerel, lancetfish,
and other tunas. Other prey items are cuttlefish, squid, octopus,
shrimp, lobster, and crabs.
