Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 5. Oxynoemacheilus zarzianus can be diagnosed from all its congeners in Tigris drainage by a combination of non-unique characters: a member of the species group (Oxynoemacheilus chomanicus, O. frenatus, O. gyndes; O. hazarensis, O. kentritesensis, O. kiabii, O. zagrosensis) which have no suborbital groove in males (vs. present in O. bergainus, O.. euphraticus; O. hanae, O. longipinnis, O. karunensis, O. kurdistanicus and O. parvinae) and slightly emarginate or truncate caudal fin (deeply emarginate or forked in O. chomanicus, O. frenatus, O. gyndes; O. hazarensis, O. kentritesensis, O. kiabii, O. zagrosensis) which have no suborbital groove in males (vs. present in O. bergainus, O.. euphraticus; O. hanae, O. longipinnis, O. bergainus, O. euphraticus; O. hanae, O. longipinnis, O. karunensis, O. kurdistanicus and O. parvinae) (Ref. 115565).

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=0.00741 (0.00354 - 0.01554), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.8   ±0.3 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).
