During spawning, Albacore females produce between 800,000 and 2.6 million eggs which hatch in about one or two days. After the eggs hatch, the fish begin to grow quickly and they remain close to the place where they were hatched for the first year of their lives. They begin to migrate after their first year. Albacore tuna have a lifespan of 11 to 12 years, but they reach reproductive maturity at around five to six years.
