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

Teleostei (teleosts) > Cypriniformes (Carps) > Leuciscidae (Minnows) > Leuciscinae
Etymology: Chondrostoma: Greek, chondros = cartilage + Greek, stoma = mouth (Ref. 45335). Name referring to the characteristic horny layer on the lower lip (Ref. 57917 ) .

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic. Temperate

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

Eurasia: West Caspian basin from Kuma to Samur drainages.

Length at first maturity / Size / Weight / Age

Maturity: L m   ? , range 12 - ? cm
Max length : 46.0 cm SL male/unsexed; (Ref. 59043 )

Short description Morphology | Morphometrics

Diagnosed from congeners in Black and Caspian Sea basins by the following characters: strongly arched mouth; dorsal fin usually with 8½ branched rays; anal fin with 9-10½ branched rays; scales on lateral line 56-73; eye small, diameter 48-52% of interorbital distance; and body cylindrical, width at dorsal origin 51-69% of depth (Ref. 59043 ).

Biology     Glossary (e.g. epibenthic)

Inhabits piedmont and mountain rivers with strong current and rock to gravel bottom. Feeds predominantly on detritus and also on periphytic algae and benthic invertebrates, especially during first year of live. Spawns over hard bottom (Ref. 59043 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Females deposit eggs probably in several portions. Eggs adhere to gravel (Ref. 59043 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00832 (0.00383 - 0.01808), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  2.4   ±0.1 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Moderate vulnerability (42 of 100).
