The vendace (Coregonus albula) is native widespread to lakes in northern Eurasia. In the Baltic Lakeland region, populations of local whitefish are remnants Arctic freshwater faunal complex and often regarded as an example a glacial relict indicator species state lake ecosystem. Together with other whitefishes belongs economically valuable fish species.; territory region located on three countries (Latvia, Lithuania Belarus). range population declining waterbodies Latvia Belarus, catch insignificant unstable, this included list specially protected species. However, not protected.; understanding genetic diversity very important for protection rare communities conservation unique populations. estimation structure determining causes differentiation factors that promote variation between within fundamental adaptation is, therefore, primary goal genetics. Little known about Lakeland.; study eight microsatellite loci were used investigate six from Lakeland, namely Drivyaty, Rudakova, Strusto, Snudi, Naroch Drūkšiai. Allelic was different all investigated populations; observed expected heterozygosity level quite high. Bayesian-based STRUCTURE analysis suggested there two main groups our area, separating Strusto into one others studied cluster. These would be differentiated due drift, reduced gene flow possibly selection promoting divergence. ;

Abstract In this study, polymorphism in behaviour, morphology, and stable isotope signatures of burbot from Lake Southern Konnevesi, Finland, Europe, was examined. First, local knowledge collected on exceptional the spawning behaviour morphology burbot. These phenomena were then studied based catch samples. Interviews sample analyses suggested two morphs burbot: one morph late February littoral zone other March, deep profundal, depths about 30 m. Fish caught profundal had higher average proportional somatic body weights wider heads than those sites February. The length-at-age individuals longer that catch. Stable analysis revealed differences mean carbon ratio between sampling sites, suggesting diet. Variability several aforementioned variables correlated. This study is first to imply populations a lake Eurasia, where are considered as near-threatened species.
