Juvenile Atlantic salmon from a landlocked population (‘Blege’, lake Byglandsfjord, south– central Norway) and an anadromous population (river Vosso, southwestern Norway) were reared in freshwater on simulated natural photoperiod (60j25VN) between December 2000 and June 2001. Fish from the Blege (me...
