how long do sturgeon live

Most sturgeon are exceptionally long‑lived fish, with many species commonly reaching 50–60 years and some individuals documented at well over 100 years old.

Quick Scoop

• Many sturgeon species have an average lifespan of about 50–60 years.

• Lake sturgeon males average around 55 years, while females often live 80–150 years.

• Some large sturgeon species (for example certain lake sturgeon and related species) are believed to be capable of living 100 years or more.

• Gulf sturgeon typically live around 20–42 years, which is shorter than some of their northern relatives.

• Green sturgeon can reach about 60–70 years of age.

Why they live so long

Sturgeon grow slowly, mature late (often not breeding until 15–20 years old), and may spawn only intermittently, which all goes hand in hand with a long natural lifespan. This slow life strategy is also why overfishing and habitat loss have hit many sturgeon populations so hard.

In simple terms: for a fish, a sturgeon is more like a “tortoise” than a “hamster” in how long it can live.

TL;DR: If you’re wondering “how long do sturgeon live,” a good ballpark is several decades, often 50+ years, with some species and large females reaching a century or more.
