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).
发现于在岩石下面被藏的寒冷的，清澈的，和快速流动的水域了。 领域性。 吃急流生物昆虫的仔鱼, 主要地孚游类与石蝇.(参考文献 26173)
