Short description Identification keys | Morphology | Morphometrics

Distinguished from its congeners in Europe by having forked caudal fin, caudal peduncle depth 1.1-1.3 times in its length, eye diameter 17-19% HL; no suborbital flap in males, lateral line reaching caudal base, and 8½ branched dorsal rays (Ref. 59043).

Occurs in the upper part of stream, with current and clear, cold water (Ref. 59043). Hides among the stones of the substrate. Stomach contents of a 6.32 cm SL female consists of aquatic insects larvae (Ref. 57755). Water abstraction may pose threat to its population (Ref. 59043).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00476 - 0.01523), b=3.08 (2.93 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.40 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
