How to identify an Albacore
The most distinguishing feature of this member of the tuna and mackerel family is its long pectoral fins that reach to a point beyond the anal fin. The pectoral fins of other adult tunas may also be moderately long, but never extend all the way to the anal fin. Though the very long pectoral fins readily distinguish the adult albacore from the other adult tunas, it should be noted that juvenile albacore might have shorter pectoral fins than similar-sized yellowfin tuna, T. albacares, or bigeye tuna, T. obesus. The albacore can be distinguished from these species at any age by the lack of stripes or spots on its lower flanks and belly and by the presence of a thin, white trailing edge on the margin of the tail fin. The liver is striated on the ventral surface. The deepest part of the albacore’s body is near the second dorsal fin, rather than near the middle of the first dorsal fin as found in other tunas. The vent is round rather than oval or teardrop shaped. The fins are dark yellowish, except for the white trailing edge of the tail, and the anal finlets are dark.
Where to catch Albacore
The albacore is found worldwide in tropical and warm, temperate seas, including the Mediterranean. As a pelagic and migratory species, the albacore usually remains in deep and clear blue tropical or warm waters, but makes seasonal migrations into colder zones (New England, South Brazil, and northern Gulf of Mexico).
