The ferox trout ( Salmo ferox ) is a species of fish from the salmon fish family (Salmonidae). It occurs in Ireland in Lough Melvin , Lough Corrib and Lough Mask , in Scotland in Loch Awe , Loch Laggan and other lakes, and probably in the lakes Ullswater and Bassenthwaite in Cumbria and in Llyn Padarn and Llyn Peris in Walesin front. Some authors consider it a subspecies Salmo trutta ferox of the trout . The exact delimitation of the species Salmo ferox and Salmo trutta is difficult.
