Comments: Inhabits deep waters of large, subalpine lakes and large to medium sized rivers.  Occurs in small groups.  Feeds in invertebrates, algae and detritus.  Moves to shallow parts of rivers to spawn (Ref. 59043). Threatened due to overfishing and construction of weirs, which block access to spawning sites (Ref. 59043) and the introduction of two alien species (European roach, <i>Rutilus rutilus and  European nase, <i>Chondrostoma nasus) (Ref. 96829).  Sexual maturity is attained at age 3+ or 4+ in males and 5+ in females at about 28-33 cm SL. Spawning occurs in April and May (Ref. 96829).  Reaches a maximum size of about 45 cm SL (Ref. 59043).
