Short description

Dorsal spines (total): 3 - 4; Dorsal soft rays (total): 8 - 11; Anal spines: 3 - 4; Anal soft rays: 7 - 10; Vertebrae: 56 - 59. Caudal fin with 18 to 20 soft rays (Ref. 40476).

Repopulation of stocks usual in Europe. Original population still exists in the island of Corse in the Mediterranean Sea (Ref. 682). Often found in fast-flowing streams of mountain and sub-mountainous regions and sometimes even valleys (Ref. 9696). Feed on benthic invertebrates, insect larvae, aerial insects (in rivers) and mollusks. In addition, adults consume fish and frogs (Ref. 30578). Utilized fresh and smoked; eaten fried, broiled, microwaved and baked (Ref. 9988).
