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.

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.
