ALBACORE TUNA (TOMBO AHI)

Scientific Name: Thunnus alalunga
Hawaiian Name: Ahipalaha; tombo ahi
Japanese Name: Tombo

Commonly called tombo ahi in Hawaii. “Tombo” means dragonfly in Japanese and refers to the very long pectoral fins of the albacore that can equal as much as 30% of the total length.

Depending on size, its flesh ranges from whitish-pink to deep pink in color. It’s the lightest and mildest in flavor of all Hawaii’s tunas. It is suitable for many different preparations. As raw fish, it is softer than the other tunas and is, therefore, more difficult to prepare as sashimi.

Fish caught in the vicinity of the Hawaiian Islands are large adults (40 to 80 pounds in weight). Hawaii albacore in excess of 50 pounds are preferred. They have a greater yield and more attractive pink color. Smaller albacore less than 20 lbs are sometimes landed in Hawaii that have pale color, but have a rich flavor due to a high fish oil content.

FISHING METHODS

All Hawaii albacore tuna are line-caught. Most of Hawaii’s albacore tuna are caught by longline fishing gear off shore of Hawaii. The remainder of Hawaii albacore landings come from handliners and trollers. Fresh Hawaii albacore are not caught in purse seine nets.

SEASONALITY

Peak harvest is from April through October.
