Description synthétique Morphologie | Morphométrie

Diagnosed from its congeners in Baltic and Black Sea basins by the following characters: longitudinal epithelial crests on predorsal scales; scales on lateral line 39-42 + 2; scale rows around caudal peduncle 14-16, rarely 12; dorsal fin with 7½ branched rays; anal fin with 6½ branched rays; dorsal behind middle of body, predorsal length greater than postdorsal length; anus closer to pelvic origin than to anal origin; snout longer than or equal to postorbital distance (Ref. 59043).

Biologie     Glossaire (ex. epibenthic)

Inhabits bottom of moderately flowing lowland rivers and prefers sand bottom. A nocturnal species feeding on insect larvae and other larger benthic invertebrates (Ref. 59043).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

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=0.00603 (0.00290 - 0.01252), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Generation time: 1.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
