There is no single tuna lifespan. It depends on the species, the ocean population and whether the figure is an average, a range or a maximum. NOAA reports about 15 years on average for Pacific bluefin, with some reaching 26 years; western Atlantic bluefin can live 20 years or more. Yellowfin generally live 6–7 years, bigeye 7–8 years, and albacore roughly 10–13 years depending on region.
Tuna lifespans by species and population
The figures below come from NOAA Fisheries species summaries unless otherwise noted. A maximum or “up to” figure should not be read as the typical lifespan.
| Species or population | Reported lifespan | What the figure means |
|---|---|---|
| Pacific bluefin tuna (Thunnus orientalis) | About 15 years; up to 26 years | NOAA’s approximate average and reported maximum; publication date is not stated on the species page. |
| Western Atlantic bluefin tuna | 20 years or more | Maximum longevity reported by NOAA; the page is dated July 2026. |
| Pacific yellowfin tuna | 6–7 years | NOAA lifespan range; publication date is not stated on the species page. |
| Pacific bigeye tuna | 7–8 years | NOAA lifespan range; the page is dated July 2026. |
| North Atlantic albacore tuna | Up to 13 years | Reported maximum; the page is dated July 2026. |
| Pacific albacore tuna | 10–12 years | NOAA lifespan range; publication date is not stated on the species page. |
| Skipjack tuna | Estimated maximum of 8–12 years | An older NOAA environmental-assessment estimate citing NOAA 2014b, rather than a current species-page summary. |
Why tuna lifespan estimates are not interchangeable
Different species mature and age on different schedules
“Tuna” describes several species, not one animal with a standard life expectancy. The cited estimates range from roughly 6–7 years for Pacific yellowfin to 20 years or more for western Atlantic bluefin.
Regions can have separate populations
Albacore illustrates the regional distinction: NOAA gives up to 13 years for the North Atlantic population and 10–12 years for Pacific albacore. Those numbers should not be combined into one global albacore lifespan.

Average, range and maximum answer different questions
- An average describes the typical value in the cited population, such as Pacific bluefin at about 15 years.
- A range gives the span reported for a species or population, such as Pacific yellowfin at 6–7 years.
- A maximum describes exceptional longevity, such as Pacific bluefin reaching 26 years or western Atlantic bluefin living 20 years or more.
Because these measures differ, it is misleading to rank every tuna species by placing a maximum beside another species’ average as though the figures were equivalent.

Among the figures listed here, Pacific yellowfin has the shortest reported range at 6–7 years. Pacific bluefin has an average of about 15 years and a documented maximum of 26 years, while western Atlantic bluefin is reported to live 20 years or more. These are comparisons of the cited species and populations, not a universal limit for all tuna.
