Description synthétique
Clés d'identification | Morphologie | Morphométrie
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).
Body shape (shape guide): fusiform / normal.
Adults inhabit lakes. Juveniles feed on zooplankton. Adults prey on zooplankton and fish, mainly Alburnus scoranza. They attain first sexual maturity at 5-6 years. Spawning occurs in January-February in littoral and sublittoral areas (Ref. 59043). Threatened by habitat destruction, overfishing and introduction of new species (Ref. 26100).
