Albacore (Thunnus alalunga) refers to a species of tuna that has long pectoral fins and is used to make canned tuna. They are also known as the longfin tuna or white tuna. This is a highly migratory species of tuna found in the waters of the Atlantic Ocean, Pacific Ocean, Indian Ocean, and the Mediterranean Sea. These fishes are high in demand and regularly caught as seafood. They are mostly found in tropical and temperate water.
Albacore tuna was first harvested for economic purposes in the 20th century. These fishes migrated to the coast of California in the Pacific, which led to people fishing for them for commercial use. Ever since then, several giant fisheries have also been put in place to increase the production of albacore as seafood. This has led to a significant decline in their population. These fishes are also caught during recreational fishing. Albacore tuna is quite a popular choice as seafood, for its impeccable taste and health benefits.

Albacore is a kind of fish belonging to the tuna species. They are also known as longfin tuna.
Albacore tuna fishes belong to the class Actinopterygii. They are a member of the Scombridae family.
Even though the exact number of albacore tuna fishes is not known, their population has been assessed to be decreasing by the International Union for Conservation of Nature or the IUCN. Though their population is not severely fragmented, it is still affected mainly due to human activities.
Albacore tuna species are found in various oceans across the world. Their locations are the Indian Ocean, the northern part of the Pacific Ocean, and the Atlantic Ocean. They are also found in the Mediterranean Sea.
Albacores are pelagic in nature, meaning they do not live too close to the surface or too close to the bottom of the water. Their population is spread out through temperate and tropical waters. The larger albacores prefer cooler areas of the water, while the smaller ones stick to the warmer areas. They are usually found up to a depth of 1968 ft (600 m) in the oceans and sea.
The albacore tuna is a solitary species. However, they are known to travel in schools even with fishes of other species while migrating. The other fishes along with whom they migrate are yellowfish tuna, skipjack tuna, and bluefin tuna.
An albacore tuna usually has a lifespan of about 11 years. However, in the Atlantic Ocean, the maximum lifespan is 13 years long and in the Mediterranean Sea, it is only nine years.
Albacore tunas are not monogamous in nature and hence, both the male and female fishes have multiple mates. The females lay between two to three million eggs and the males release their sperms in the water. The females are known to scatter their eggs in the water. Following that, external fertilization takes place. Since these tuna species are highly migratory in nature, they migrate to more tropical waters during the breeding season. The adult albacore tuna does not show any parental care towards their offsprings.
The conservation status of the albacore tuna has been listed as Least Concern by the International Union for Conservation of Nature. Their main threat is humans. Since this is a popular breed of fish caught to be sold as canned tuna, their population is being severely affected. Several conservation measures are taken to ensure these fishes do not face a drastic decline.
The tuna albacore is characterized by a pair of big eyes and a pointed snout. Their body is torpedo-shaped. The upper side of the body appears dark blue and iridescent, while the underside has a silvery-white appearance. Another interesting feature of this tuna is its long pectoral fins. The fishes which measure more than 20 in (50 cm), have pectoral fins which are 30 percent of their total length. Their dorsal and anal fins have a hint of yellow. In this species, the male and female fishes appear the same in appearance. But as they grow older, the male fishes start looking bigger.
The albacore tuna fish does appear quite cute. Their unique iridescent torpedo-shaped body adds to their charm.
There is not a lot of detailed information on how an albacore tuna communicates with members of its own species or other species. But like most other fishes, they are thought to successfully communicate through audible, visual, tactile, and chemical methods.
The length of the body of an albacore tuna can grow up to 55.1 in (140 cm). This species of tuna is significantly smaller in size when compared to the bluefin tuna species, which can grow as long as 13 ft (4 m).
The albacore tuna is known to be quite a fast swimmer. Being migratory in nature, they attain speeds of about 50 mph (80 kph) while migrating across the waters.
The weight range for an albacore tuna is between 5-100 lb (2.2-45.3 kg), averaging at around 80 lb (36.3 kg).. However, the maximum weight to be recorded was 133 lb (60.3 kg). The immature albacore tunas weigh less than 30.8 lb (14 kg).
The male and female fishes belonging to this species are known as male albacore tuna and female albacore tuna, respectively.
A baby albacore tuna would be called an albacore tuna larva.
Albacore tuna mainly feeds on other smaller fishes, plankton, mollusks, and crustaceans. Their most common prey is the anchovy fish, which is a smaller fish species. However, if there is a lack of this type of fish, they can eat other species as well. Hence, they are considered to be opportunistic feeders.
An albacore tuna fish is not really dangerous to humans when alive. But, since they accumulate a lot of mercury, it can pose a health threat to humans. Hence, it is advisable to not consume canned tuna on a regular basis.
Albacore tuna fishes are not known to be kept as pets. Since albacore tuna is a larger fish with certain specific requirements, it might be difficult to keep them as pets.
The name albacore is derived from the Portuguese word 'albacora' meaning, yellowfin.
Some of the common predators that prey on albacore are larger tunas, sharks, rays, and so on.
There are a total of six stocks of albacore tuna and each stock has a different pattern of migration. For instance, the stock belonging to the north of the Atlantic is seen to migrate near the Bay of Biscay, which is located near France and Spain.
Albacore is one of the most popular choices of seafood among people. This fish is sold as white tuna in the market. In fact, it is the only species that are allowed to be labeled as white meat tuna. They are available in fresh as well as canned form. The white fish meat is supposed to be rich in omega-3 and vitamins A, B, and D. Albacore fish is one of the most economically viable fish meat, prompting several large-scale fisheries to produce albacore tuna. Albacore fishing is also carried out using methods like long-line fishing, trolling, and purse seining.
Even though albacore is a kind of tuna, there are a few differences between the two. There are several kinds of tuna fish like bluefin tuna, yellowfin tuna, bonito tuna, and so on. Hence, tuna is a much broader term, whereas albacore refers to a specific kind of tuna. Unlike most tuna, albacore tuna has a much higher fat content. They are also much more expensive when compared to regular tuna. The taste of albacore tuna is also different from regular tuna. The former does not taste as fishy or as metallic as the latter.
