Potential Trophic Competition Between the European Perch Perca fluviatilis and Pikeperch Sander lucioperca

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT The European perch Perca fluviatilis and pikeperch Sander lucioperca can co‐occur, potentially competing for food resources. However, few studies have addressed the potential feeding competition between these species. We used carbon and nitrogen stable isotope analysis to assess the potential trophic competition between these species in two ...
