Scardinius erythrophthalmus

  • 1. Eawag: Das Wasserforschungsinstitut des ETH-Bereichs Überlandstrasse 133, CH- 8600 Dübendorf

Description

S. erythrophthalmus

was recorded in almost all northern perialpine lakes, except Thun, Brienz, Walen, Upper Zurich and Joux. S. hesperidicus was recorded in all southern perialpine lakes. Despite being previously reported in the region, no phenotypes of S. erythrophthalmus were recorded in the southern lakes, and all genetically barcoded Scardinius from the southern lakes were S. hesperidicus. We note that subadult S. hesperidicus can have bright orange-red fins, which can lead to confusion with S. erythrophthalmus. The presence of the latter species south of the Alps hence remains to be confirmed.
