Short description
Chiavi di identificazione | Morfologia | Morfometria
This species is distinguished from the other members of the O. brandtii species group (brandtii, elsae, merga) by having a slightly emarginate caudal fin (vs. forked in brandtii, deeply emarginate in elsae, merga); pelvic fin not reaching to origin of genital papillae (vs. reaching to or beyond anus in brandtii and many elsae, merga); caudal peduncle 1.5–2.1 times longer than deep (vs. 2.5–3.2 in brandtii, 2.3–2.9 in elsae, 2.0–2.5 in merga); and a mottled or marbled flank pattern (vs. usually with irregularly shaped and spaced, dark-brown bars or vertically elongate blotches on flank posterior to dorsal-fin origin, much wider than interspaces, often fused into a plain brown pattern on flank in front of dorsal-fin base in brandtii; usually with irregularly shaped and spaced, rarely regularly shaped and spaced, dark-brown bars, often split in middle, or flank almost plain brown in elsae; with many, narrow, pale-brown bars, usually much more narrow than interspaces, often dissociated in vertically elongate blotches on flank and dorsal saddles, rarely mottled in merga) (Ref. 125990).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [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
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
