Short description Identification keys | Morphology | Morphometrics

Paracobitis atrakensis is diagnosed from other congeners in the Middle East by a combination of the following non-unique characters: absence of scales on the body, but presence of isolated scales on the dorsal adipose crest in a few of the individuals examined (vs. body fully covered by scales in P. longicauda and P. rhadinaea; posterior flank behind dorsal-fin origin covered by scales in P. malapterura, P. basharensis, P. molavii, P. persa and P. zabgawraensis). Both P. smithi and P. vignai lack scales on the body. P. atrakensis differs from P. smithi by having normally developed eyes (vs. absence ), a truncate or slightly emarginate caudal fin (vs. forked) and a dark brown color patter (vs. no color pattern). It can be separated from P. vignai by having a truncate or slightly emarginate caudal fin (vs. forked) and a roundish posterior nare opening (vs. slit-like) (Ref. 98825).

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=0.00724 (0.00387 - 0.01357), b=2.95 (2.80 - 3.10), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±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).
