Salmothymus is a genus name of fish in the family Salmonidae, established for the Adriatic trout (Salmothymus obrusirostris). More commonly, however, the species is considered a member of the wider genus Salmo , i.e. Salmo obtusirostris. [1] [2] Salmothymus thus is a junior synonym of Salmo, not in current use.
