Morphology | Morphometrics
Diagnosed from congeners in western Europe by the following characters: lacking keel from nape to dorsal origin; snout projecting, pointed; upper jaw projecting; dorsal profile of head and body continuously rounded, usually lacking marked hump; lips thick and fleshy; eye diameter 19-21% HL; snout length 32-34% HL; and lateral line with 47-49 + 3 scales (Ref. 59043).
Inhabits streams and rivers, sectors with current, clear and cool, in deep pools. Adults undergo small migrations. Spawns at night in stretches with swift current and pebble bottom, in deeper pools (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (60 of 100) .
