The Åland Islands are major feeding grounds for threatened whitefish, Coregonus lavaretus (Linnaeus, 1758), in the Gulf of Bothnia, Baltic Sea. Diet of the foraging whitefish, however, has been poorly studied in this area. In the presently reported

In this work we describe an application of particle-induced X-ray emission (PIXE) to the elemental analysis of polished otoliths of whitefish. Two spots on polished otoliths were irradiated; one spot in the core region of the otolith and another one

To investigate whether European whitefish (Coregonus lavaretus) groups in the brackish (≤7%) Gulf of Bothnia (Baltic Sea) express specific otolith elemental characteristics, concentrations of elements (Ca, Ba, Sr, Zn, Mn, Fe) in whole otoliths were

Divergent selection at ecologically important traits is thought to be a major factor driving phenotypic differentiation between populations. To elucidate the role of different evolutionary processes shaping the variation in gill raker number of Europ

Otoliths of perch ( Perca fluviatilis ), pike ( Esox lucius ) and European whitefish ( Coregonus lavaretus ) caught at different locations in the northern Baltic Sea along the Finnish west coast and at some rivers and lakes were subjected to elementa

Osmoregulation is a vital physiological function for fish, as it helps maintain a stable intracellular concentration of ions in environments of variable salinities. We focused on a primarily freshwater species, the European whitefish (Coregonus lavar

Enzyme gene variability has been studied by starch gel electrophoresis in 20 Finnish vendace (Coregonus albula) populations. Eighteen populations originate from fresh water and two from brackish water. Fourteen populations spawned in the time typical

European whitefish (Coregonus lavaretus) occurs as two ecotypes in the Gulf of Bothnia, Baltic Sea (Fig. 1). The ecotypes, anadromous river spawning and stationary sea spawning whitefish, mix at sea off breeding location and time. They have similar o
