From: Eye fluke infection changes diet composition in juvenile European perch (Perca fluviatilis)
Stable isotope biplot of individual YOY perch (Perca fluviatilis) and their major prey categories sampled at the northern shore of Lake Müggelsee in 2016. Fish are divided in two categories based on eye fluke infection intensity: low infection intensity ( ×) = 5 ± 3 metacercariae per fish (average ± SD) and high infection intensity fish (Δ) = 39 ± 13 metacercariae per fish (average ± SD). Perch δ13C and δ15N signatures were corrected for fractionation by 1 ‰ and 3.5 ‰, respectively. Prey stable isotope signatures are shown as mean ± SD.
