Distinguished from all its congeners in Balkan Peninsula by the combination of the following characters: lacustrine; size reaches up to at least 60 cm SL; in large adults, head and body silvery, with black spots, especially in upper part, red spots (when present) mainly along lateral line; flesh pinkish. Can be diagnosed from at least Salmo balcanicus and Salmo aphelios by its osteological characters (Ref. 59043). (Ref. 59043).
Inhabits lakes. Juveniles feed on zooplankton. Adults prey on zooplankton and fish, mainly Alburnus scoranza. Attains first sexual maturity at 5-6 years. Spawns in January-February in littoral and sublittoral areas (Ref. 59043). Threatened by habitat destruction, overfishing and introduction of new species (Ref. 26100).
