Diagnosed from other prealpine charrs by the following combination of characters: mouth subinferior; snout blunt; 19-25 gill rakers; flank yellowish to silvery, sometimes with faint pale spots; eye diameter 0.8-1.4 times in interorbital; head depth at eye 9.4-11.4% SL; body depth at anal-fin origin 10.6-14.7% SL (Ref. 56679). Also distinguished from congeners in central Europe by its fin hyaline to whitish, with white margins in mature males (Ref. 59043).
Inhabits deep water, below 80 m. Spawns in all seasons with a peak in September and October (Ref. 59043).
