Etymology: Cottus: Greek, kottos = a fish (Ref. 45335);  duranii: Named for Duranius (Durranus, Dordonia, etc.), the Latin name of River Dordogne which is the type locality of the species..   More on author: Freyhof, Kottelat.

Environment / Climate / Range Ecology

Freshwater; benthopelagic.   Temperate

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Europe: Upper Dordogne and upper Loire drainages in France. Populations from upper Lot are possibly conspecific.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 89113)

Short description Morphology | Morphometrics

Anal soft rays: 12 - 13. Differs from all species of Cottus in Europe by the dorsal fins usually separate in both sexes. Other characters useful to distinguish the species from other Cottus in Atlantic drainages include: relatively elongated body; first dorsal fin low, slightly rounded or regularly slanted; caudal peduncle stout (length 14-20% SL; depth 8-9% SL and 1.5-2.4 times in its length); no prickling in adults; eye diameter 19-26% of HL; interorbital distance 0.9-1.2 times in eye diameter; last anal-fin ray connected to body by a membrane at most along 1/4 of its length; last dorsal-fin ray connected to body by a membrane along 1/2-4/5 of its length; no membrane between pelvic fin and body; pelvic-fin ray 1 straight and slender; lateral line complete (Ref. 55856).

Biology     Glossary (e.g. epibenthic)

Inhabits streams with clear, cool, moderate to swift water and stone substrate (Ref. 59043).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00341 - 0.02227), b=3.12 (2.89 - 3.35), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (35 of 100) .
