Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 8; Anal spines: 3; Anal soft rays: 7 - 8; Vertebrae: 37 - 38. Diagnosed from its congeners in Iberian Peninsula by having the following characters: infraorbitals 4 and 5 very large, completely fused; 33-40 + 2 scales on lateral line; snout rounded; mouth subterminal, upper jaw projecting; head length less than body depth; and 2½ -3 scale rows between lateral line and pelvic fin origin (Ref. 59043). Preopercular-mandibular canal communicates with infraorbital canal (Ref. 28035).
Body shape (shape guide): fusiform / normal.

Biology     Glossary (e.g. epibenthic)

An ubiquitous species which inhabits small to medium sized streams with Mediterranean water regime. May be restricted to very small pools during summer. Breeds in shallow riffle habitats in fast-flowing water (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=0.00813 (0.00411 - 0.01607), b=3.13 (2.97 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
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). 🛈
