Spatial-temporal variability of mercury content in the river perch Perca fluviatilis Linnaeus, 1758 (Perciformes: Percidae) of the Rybinsk Reservoir at the turn of the XX–XXI centuries

The amount of mercury (Hg) in the muscle tissue of the river perch (Perca fluviatilis Linnaeus, 1758) from different stretches of the Rybinsk reservoir was measured in a period from 1997 to 2012. Mercury concentrations were higher in muscles of perches from the Sheksna and Volga reaches, and lower i...
