Albacore fish (lat. Thunnus alalunga)
A member of the Scombridae family of tuna and mackerel,
the albacore is an excellent light-tackle gamefish. It is called
true albacore in some places, not to be confused with false
albacore or little tunny (see).
OTHER NAMES:
longfin tuna, long-finned
tunny, longfin, true albacore,
albacore tuna, albie,
and pigfish; French: germon;
Hawaiian: áhi pahala;
Japanese: binchô, binnaga;
Portuguese: albacora;
Spanish: albacora, atún
blanco.
The albacore has long pectoral fins that
reach to a point beyond the anal fin, as well as small finlets
on both the back and the belly that extend from the anal fin
to the tail. The albacore is colored dark blue, shading to
greenish-blue near the tail, and is silvery white on the belly.
A metallic or iridescent cast covers the entire body. The dorsal
finlets are yellowish, except for the white trailing edge of
the tail, and the anal finlets are silvery or dusky.
The average weight for albacore is between 10 and
25 pounds. The all-tackle record is 88 pounds, 2 ounces,
although commercially caught fish have weighed as much
as 93 pounds. The albacore can grow to 5 feet in length.
A schooling fish, the albacore is
migratory and pelagic; that is, it lives and feeds in the open
sea. It roams widely, varying in location from within a few
miles of shore to far offshore, as currents and water temperatures
dictate. Its availability can change widely from
year to year. Albacore have been described as one of the
world’s fastest migrant fish, and tagging studies have
tracked them across entire oceans.
Albacore spawn from July through October along the
west coast of North America and in the summer season in
the Southern Hemisphere of the mid-Pacific.
The albacore diet consists of
fish, squid, and crustaceans. Albacore feed in schools, which
sometimes consist of other tuna-family members, and these
schools are typically found around floating objects such as
sargassum. Although they will feed at middle depths, they
ordinarily feed close to the surface.
Albacore are
found worldwide in tropical
and temperate seas, including
the Mediterranean, but
they also make seasonal
migrations into colder zones
such as New England,
southern Brazil, and the
northern Gulf of Mexico. In
the western Atlantic, albacore
range from Nova Scotia
to Brazil, although they
rarely range north of New
York and are absent from
the Straits of Florida; in the
Pacific Ocean, they range
from Alaska to Mexico.
Albacore are abundant in
the Pacific but less common
in the Atlantic.
Albacore favor
tropical, subtropical, and
temperate waters, commonly
in the 60° to 66°F
range. These fish seldom
come close to shore and
prefer deep, wide-open
waters.
