Sturgeon are known for their long lifespans, with variations depending on the species:

• Generally, sturgeons live on average 50 to 60 years, with some species maturing late, around 15 to 20 years of age

• The European sturgeon can live up to 150 years, which is exceptionally long compared to most fish

• Atlantic sturgeon live up to 60 years in northern regions like Canada but tend to live shorter lives, around 25 to 30 years, in the southeastern U.S.

• Lake sturgeon are among the longest-lived, with males living around 55 years and females potentially reaching 80 to 150 years

• Gulf sturgeon have a life expectancy between 20 and 42 years, with some individuals documented at 42 years old

• White sturgeon can live 100 years or more, especially in certain river systems

In summary, sturgeon lifespans range broadly across species, from about 20 years to as much as 150 years, with lake and European sturgeons among the longest-lived.
