Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Cypriniformes (Carps) > Leuciscidae (Minnows) > Leuciscinae
Etymology: Pseudochondrostoma: Name refers to its morphological similarity with the genus Chondrostoma as a consequence of homoplasy in multiple traits..

Short description Identification keys | Morphology | Morphometrics

Diagnosed from its congeners by having the following characters: lower jaw edge straight; 61-75 + 3-4 scales on lateral line; anal fin usually with 9½ branched rays; 22-31 gill rakers; usually 6-5 pharyngeal teeth; and caudal peduncle depth 1.8-2.2 times in its length (Ref. 59043).

Biology     Glossary (e.g. epibenthic)

Inhabits middle stretches of rivers in areas with current. Can survive in reservoirs. Occurs in groups, especially during pre-reproduction migration (Ref. 59043). Also found in lakes (Ref. 26100). Feeds on vegetal matter, small invertebrates and detritus (Ref. 59043). Spawning occurs in spring in shallow water, on gravel and sometimes on timber pilings in the river. Threatened due to the introduction of other species (Ref. 26100).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00486 - 0.01360), b=3.13 (2.99 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.5   ±0.24 se; based on food items.
Generation time: 6.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.18; tm=2; tmax=7).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100).
Price category (Ref. 80766):   Unknown.
