Albacore Tuna

Thunnus alalunga



Unlike many fish, albacore tuna are unable to pump water through their gills, forcing them to constantly swim with their mouths open.

Taxonomic description

  • Can be identified by its metallic dark blue back and silver belly as well as its dark yellow first dorsal fin and pale yellow second dorsal fin. A deeply forked, crescent shaped tail fin helps generate the power needed to maintain its impressive speed. [1]
  • This fish can reach up to 1.5 meters in length. [2]


  • Found in the tropical, sub-tropical, and temperate zones of the Indian, Atlantic, and Pacific oceans. [1]

Life history

  • It can live up to 10 -12 years. [1]
  • Reaches sexual maturity at 5-6 years and spawns from March through July (possibly multiple times per year). Females will broadcast spawn, releasing between .8 to 2.6 million eggs every time they spawn. Fertilized eggs hatch within 24-48 hours. [1]


  • It is found in waters of 13.5° to 25.2° C. [2]
  • This fish is a top carnivore in the food chain, feeding on anchovy, squid, and sardines. It is preyed upon by humans, sharks, billfish, and other tunas. [1]
  • Primarily feeds by sight so it is limited to daytime feeding hours, although it has been known to occasionally feed at night. [1]



Since Albacore tuna is a highly migratory species crossing over multiple international boundaries, management efforts require extensive international cooperation.

Seasonal availability

  • May be fished commercially year-round, but highest availability is typically from July to August. [3,5]

Regulatory and Managing authority

  • It is internationally overseen by the Inter-American Tropical Tuna Commission (IATTC) and the Western and Central Pacific Fisheries Commission (WCPFC). [1]
  • Along the Pacific West Coast, this fishery is overseen by NOAA fisheries and, as established by the Magnuson-Stevens Act, the Pacific Fishery Management Council through the West Coast Highly Migratory Species Fisheries Management Plan. [1]
  • As established by the Marine Life Management Act, the California Department of Fish and Wildlife (CDFW) collects data on this fishery through the Pelagic Fisheries Ecosystems Program. [9,12]
  • The American Albacore Fishing Association combines input from the industry and government entities to inform regulatory and management measures for this fishery. [11]

Gear type

  • Fishing methods for catching albacore include longline, gillnet, pole and line, purse sein, trolling. [3,4]
  • Along the Pacific West Coast, most commercially landed albacore tuna is caught by troll and pole-and-line gear. [1]

Status of the fishery

  • According to 2015 and 2017 stock assessments, the North and South Pacific stock is not overfished or at risk of being overfished due to successful regulation and monitoring programs. [1]
  • Population size is above target levels. [1]
  • Protective regulations include limits on longline permits, protected species workshops, and a vessel monitoring program. [3]
  • International Scientific Committee for Tuna and Tuna-like Species in the North Pacific provides scientific analysis and recommendations to aid in conservation efforts. [1]

Potential ecosystem impacts

  • Since the gear associated with Albacore fishing rarely touches the seafloor, impacts to habitat are minimal compared to other methods. [1]
