Abstract: Sturgeons are a significant and ancient group of fish, often referred to as "living fossils" because their morphology has remained largely unchanged for millions of years. As some of the earliest extant vertebrates, their evolutionary history offers valuable insights into the development and diversification of vertebrates. However, human activities such as overfishing, habitat destruction and environmental pollution have severely impacted their populations. As a result, the majority of sturgeon species are now classified as endangered, vulnerable, or even extinct in the wild. Understanding the genetic diversity of sturgeons is critical for their conservation and for maintaining the long-term viability of their populations. Genetic studies using tools such as microsatellite markers and mitochondrial DNA (mtDNA) genotyping provide detailed information about the population structure, genetic variation and degree of inbreeding among sturgeon populations, enabling researchers to assess population health, understand phylogenetic relationships, support aquaculture programs and develop effective conservation strategies.The continued research into their genetic diversity and evolutionary history contributes to a broader understanding of biodiversity and the dynamics of ancient vertebrate lineages.
