The lake grey trout comes from the family of the salmon fish. Genetically she is the same fish kind like the sea trout and the brook trout. Other names for the lake grey trout are blue trout, golden salmon and basic trout.
The arctic char (Namaycush) belongs to the family of the salmon fish. In winter time guests like to fish Namaycush on the frozen lake. In summer time it is difficult to catch a arctic char because they stay primarily in the deep, cold water.
The lake trout is marked by the ice age and lives mainly in lakes with rich oxygen up to the height of 2600 meters. The mountain lakes on Melchsee-Frutt offer therefore an excellent habitat for the lake trout.
