Long‐term shifts in pikeperch, Sander lucioperca, diet composition in a changing reservoir

open access: yesJournal of Fish Biology, EarlyView.
Abstract As a significant piscivorous predator, the pikeperch (Sander lucioperca) plays a critical role in regulating aquatic ecosystems. Understanding its size‐related feeding behaviour is thus vital for assessing its impact. To evaluate its role in the ecosystem, stomach content analysis provides useful insights into predator–prey dynamics.
