Kurzbeschreibung Morphologie | Morphometrie

Distinguished from all its congeners in Adriatic basin by having the following unique characters: lips fleshy; lateral line scales elliptical, reduced to little more than nerve tube, smaller than scales in adjacent rows; 100-120 scales along lateral line; 26-32 gill rakers. Differs further by the combination of the following features: jaw teeth small or indistinct; snout blunt; and mouth subinferior (Ref. 59043).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found in water courses at high altitude (Ref. 26100). Inhabits cold streams and small rivers, usually in deep, quiet places. Occurs in groups. Feeds on invertebrates. Spawns in April-May. Attains a maximum size of about 70 cm SL (Ref. 59043). Threatened by the construction of dams, introduction of new species and overfishing (Ref. 26100).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00763 - 0.02175), b=3.01 (2.87 - 3.15), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.5 se; based on size and trophs of closest relatives
Generation time: 4.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.3).
Verwundbarkeit (Ref. 59153):  Moderate to high vulnerability (47 of 100) .
Preiskategorie (Ref. 80766):   Very high.
