Short description Identification keys | Morphology | Morphometrics

This species is distinguished from O. ercisianus, O. hazarensis, O. kaynaki by possessing a long and high dorsal adipose crest with a whitish margin, reaching beyond the vertical through the anal-fin origin, often below the last dorsal-fin rays when folded down (vs. absence or with a short dorsal-adipose crest, without white margin, on the caudal peduncle not reaching to the vertical through the anal-fin base); with 10-16 bold, narrow, regularly shaped bars, very distinct on the caudal peduncle (vs. a mottled or marmorate flank pattern or the flank with large, irregularly shaped and narrowly spaced dark-brown bars or blotches); most individuals with two bold, black spots at the caudal-fin base (vs. no spots); many isolated, deeply embedded scales on the flank (vs. scales absent in O. ercisianus, scales confined to the caudal peduncle in O. hazarensis)(Ref. 120397).

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=0.00692 (0.00439 - 0.01091), b=3.08 (2.95 - 3.21), in cm total length, based on LWR estimates for this species & 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).
