Genetic relatedness between Baltic Sea sturgeon (Acipenser sturio L.) specimens caught in different geographic areas is not clear. According to previous studies, fish captured in different locations within the historic area of A. sturio habitation are genetically different to each other. We have examined a fragment (191 base pairs) of mitochondrial cytochrome b gene of four specimens of A. sturio found in Poland: three fish were preserved in museums of natural history and the bone of one fish was from an archaeological site. DNA sequences of the three museum samples were identical, whereas the DNA sequence of the archaeological sample differed in the 918 position of the cytochrome b gene. All the analyzed DNA fragments were similar to those of Acipenser baeri and genetically distant to Acipenser sturio and A. oxyrinchus.
