Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 7 - 8; Mjukstrålar i ryggfenan (totalt) : 8 - 9; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 6 - 7; Ryggkotor: 29. This species can be distinguished from its congeners by the following characters: D1 VI-VII, D2 I,8-9; longitudinal scale series usually 22-24 (most commonly 23), while the transverse scale series typically comprises 7-8 scales (most commonly 8); predorsal scale series absent; total vertebrae 12 + 17 = 29; a black line stripe beneath the eye that extends to the mandible (Ref. 132591).
Cross section: oval.
Occurs mainly in areas characterized by large cobblestone substrates and slow-flowing water at depths ranging from approximately 30-50 cm. This species utilizes the cobblestone bottom as an egg deposition site, with eggs characterized as large (size 1.6-2.1 mm). During periods of high water levels in the creek, individuals aggregate near the shore to seek refuge from the rapids (Ref. 132591).
