The Albacore Tuna, or longfin tuna, is a large smooth-skinned pelagic fish that roams the open oceans in massive schools.
As one of the main cornerstones of the world’s fishing industries, albacore stocks are carefully managed by governmental agencies to prevent overfishing.
3 Incredible Albacore Tuna Facts
- Schools of albacore can stretch up to 19 miles wide. They are sometimes accompanied by skipjack, yellowfin, and bluefin tuna.
- Albacore swims at speeds of around 50 miles per hour.
- Albacore has a very high metabolism and consumes up to 25% of its body weight in food per day.
Evolution And History
The albacore comes from a large family of tuna that is generally split into two species – the Thunnus and the Sardini. The Thunnus are often considered the “true” tunas although they most likely have origins from the same evolutionary timeline. The tuna can be traced back to an exothermic ancestor based on early tuna fossils that were discovered from the late Paleocene era in sea deposits.
Classification And Scientific Name
The scientific name of the albacore is Thunnus alalunga. This appears to be the combination of two words: ala, meaning wing, and lunga, meaning long.
Types Of Albacore
While albacore is part of the species of tuna called Thunnini, which incorporates 15 different types of tuna, there are 5 specific species of tuna that are referred to as albacore, depending on which part of the world you’re in. These 5 are:
- Blackfin tuna (Thunnus atlanticus)
- Yellowfin tuna (Thunnus albacares)
- Yellowtail amberjack (Seriola lalandi)
- Kawakawa (Euthynnus affinis) – this is a false albacore, which means that they have differences in coloration, body markings, teeth, and where they search for food.
- Little tunny (Euthynnus alletteratus) – another false albacore.
Appearance
The Albacore is one of the smallest tuna species. Weighing around only 80 pounds, it is just slightly larger than the skipjack. The albacore has a dark blue or gray back, which fades to silver or white around the stomach. The most prominent characteristic is the massive pectoral fin on the side of the body. This is how it acquired the alternate name longfin.

Distribution, Population, And Habitat
The albacore has distinct stocks in the northern Pacific and southern Pacific. It’s also found in the Atlantic, the Indian Ocean, and the Mediterranean Sea. According to the IUCN Red List, this species is considered “least concern“. Although many populations are responsibly managed, others are in steep decline.
Predators And Prey
The albacore is a top open sea predator. Its speed and size give it an inherent advantage over many other species.
What Does The Albacore Eat?
The albacore is the only tuna species that feeds primarily on squid and other cephalopods. Crustaceans and fish are secondary sources of food.
What Eats The Albacore?
The albacore is preyed upon by billfish, sharks, rays, and other tuna.
Reproduction And Lifespan
Returning to tropical waters each year to reproduce, the female will release eggs into the water.

The albacore returns to the tropical waters every year around the summer season to reproduce. Depending on her size, the female will release between 800,000 and 2.6 million eggs into the water. The few albacores that survive into adulthood reach sexual maturity at five or six years and live up to 12 years.
Albacore In Fishing And Cooking
The albacore is critically important to commercial and recreational fisheries around the world. With its mild taste and firm meat, this species accounts for about 30% of the canned tuna market. Common recipes include grilled albacore, steaks, salads, sushi, and sashimi.

How does skipjack tuna compare to albacore tuna?
The primary difference between skipjack tuna and albacore tuna is that skipjacks are generally smaller, have shorter pectoral fins, and are considered a lower quality of meat for cooking. The annual skipjack catch is more than 10 times the size of the albacore tuna catch.
How do Albacore Tunas have babies?
Albacore Tunas lay eggs.
What are the key differences between yellowfin tuna and albacore?
