Migratory patterns and cyanotoxin concentrations of pikeperch (Sander lucioperca) in the coastal waters of the Baltic Sea
We used stable isotopes of sulfur (δ34S) and carbon (δ13C) to distinguish resident and migratory pikeperch (Sander lucioperca) among individuals captured from a coastal freshwater lagoon (Curonian Lagoon) and adjacent Baltic Sea waters. We found that non-migratory pikeperch collected from the lagoon...
