The honourable Natural Research Society of Zurich has just published its 224th New Year's Bulletin. It is devoted entirely to the eight square kilometre Greifensee, which Eawag is also researching intensively.
In the "Projet Lac" research project, 35 lakes in the Alpine region were systematically examined for their fish populations for the first time: In Switzerland alone, 106 fish species were detected. With almost 20 percent of all known fish species in Europe, Switzerland is one of the hotspots for fish species diversity. The results are now the basis for measures for sustainable fishing and the protection of this still preserved diversity.
