Summary Sea trout ( S almo trutta m. trutta ) is a migratory form of brown trout common in the B altic Sea. Nine populations from the southeast B altic ( P oland; L ithuania; D enmark, B ornholm; E stonia and R ussia) were genotyped using iPLEX Gold technology (Sequenom) with 62 informative SNP s. A diagnostic panel of 23 SNP s was applied to estimate genetic differentiation and assess the population structure of B altic sea trout. The highest level of pairwise F ST differences was observed between the R ussian (East Gulf of F inland) and Polish ( B altic main basin) populations. The lowest differences were between the two Polish and the Polish and L ithuanian populations. A genetic similarity was noted between the E stonian Riguldi River and Danish Bornholm populations, and this finding was supported by a Bayesian and factorial correspondence analysis. Diversity within populations was highest for populations from E stonia and lowest for the L ithuanian population. Genetic structure analysis indicated that individuals from the nine populations were clustered into four groups.
