Lake sturgeon may live over 400 years, reveals new research
Scientists have discovered that lake sturgeon, freshwater giants native to North America, could potentially live for more than four centuries. The finding significantly extends previous understanding of the species' lifespan and longevity.

A new scientific study has revealed that lake sturgeon possess an extraordinarily extended lifespan, potentially exceeding 400 years. The research challenges earlier estimates of the species' maximum age and underscores the remarkable biological durability of these ancient fish.
Lake sturgeon, which inhabit freshwater systems in North America, are among the longest-living fish species known to science. Their extreme longevity is attributed to slow growth rates, delayed sexual maturity, and low metabolic rates—characteristics that contribute to their exceptional resilience and durability.
The findings have implications for conservation efforts and fisheries management, particularly given that many sturgeon populations have faced significant decline due to overfishing and habitat loss. Understanding the true lifespan of these fish is crucial for developing effective long-term conservation strategies and determining sustainable harvesting practices.
The extended longevity of lake sturgeon makes them invaluable for studying aging processes and longevity mechanisms in vertebrates. Scientists believe further research into the biological factors enabling their extreme lifespan could yield insights applicable to other species and human aging research.
The study adds to growing evidence that sturgeon species represent living archives of freshwater ecosystems, with some individuals potentially spanning multiple human generations and witnessing centuries of environmental and ecological change.
