Scatterplots of the measured of stable isotope values (δ13C and δ15N): A distribution between the sampling stations; B distribution between the groups assigned by means of the clustering analysis; C cluster dendrogram indicating new grouping of the sampled perch, where blue—group 1, green—group 2, red—group 3, purple—the mixed group 4 (potential recent arrivals, isotope values cannot be attributed to any of sampling stations)
