Native fish species under pressure in the Engadine, Poschiavo

18 marzo 2015

From 2010 to 2014, a total of 26 prealpine lakes were studied as part of Projet Lac, with over 60 fish species being recorded. In 2012, surveys were carried out on Lake Sils in the Engadine and Lago di Poschiavo. The results, now available, show that both of these lakes harbor a commercially attractive salmonid community. However, both lakes’ historical diversity has been significantly affected by the introduction of fish species from several other catchments – in particular, the Arctic char (Salvelinus alpinus), Canadian lake trout (Salvelinus namaycush) and brown trout (Salmo trutta).
