The aim of this study is to help the conservation effort of the Acipenser gueldenstaedtii Brandt et Ratzeburg, 1833 population from Lower Danube, ensuring its sustainable development in regards to aquaculture and wild populations. We evaluated the genetic diversity of five aquaculture strains using molecular markers, determining the suitability of employing the individuals in ex situ conservation and in restocking programs. The mitochondrial cytochrome b gene analysis highlighted that some sequences from aquaculture and wild populations are grouped together representing a single haplotype. Results showed that the five aquaculture strains are grouped in 3 haplotypes with a haplotype diversity of 0.55686. The microsatellite analysis highlights that the majority of loci have a tetrasomic profile that makes the inferring of genotypes and the statistical analyses difficult, only two (AciG198 and Spl106) had a disomic profile that could prove useful in future studies. We can conclude that the molecular analysis is important for the genetic characterization of aquaculture strains, shedding light on the genetics of A. gueldenstaedtii
