Short description
Morfología | Morfometría
Distinguished from other species of Percidae in Europe by the following combination of characters: first dorsal fin with 8-9 spines; 58-68 scales on lateral line; mouth inferior, horse-shoe shaped; lacking air-bladder; two dorsal fins clearly separated from each other; and anal fin with 7½ branched rays (Ref. 59043).
Inhabits fast-flowing, cold and clear mountain streams. Usually hidden under stones. Active at night (Ref. 59043). Feeds on larvae of rheophilic insects, mainly mayflies and stoneflies (Ref. 26173). Territorial. Spawns possibly in second half of May. Deposits 120-150 eggs under stones (Ref. 59043). On the edge of extinction due to deforestation, construction of roads, extraction of stones and dam constructions (Ref. 59043).
