Feeding range of age 1+ year Eurasian perch Perca fluviatilis in the Baltic SeaBergendahl, I. Ahlbeck; Holliland, P. B.; Hansson, S.; Karlof, O.
AbstractUsing the widespread Eurasian perch Perca fluviatilis as a model organism, feeding ranges were investigated using stable-isotope ratios (N-15 and C-13) and body condition. Differences were found between closely located sampling sites in a littoral area without obvious migration barriers, indicating that individual fish had small feeding ranges. Body condition differences between sampled stations were consistent over 4 years. Such sedentary behaviour is important to consider in, e.g. fisheries management and environmental monitoring, as local catch regulations may be meaningful or geographic stability in sampling locations may reduce noise in data.
