Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. Diagnosis: This species differs from its congeners by the following combination of characters: squamation is reduced to axillar and caudal peduncle patches, unconnected or connected with single row along lateral midline; the anterior oculoscapular canal is present, ending anteriorly with or without pore ?; the preopercular canal is present (at least in a part of the population); the pelvic frenum has a crenate rear edge; suborbital longitudinal row b anteriorly beginning below rear border of eye; anterior dorsal row m is present; oculoscapular row u absent; single papilla of interorbital row p is present, at least in a part of a the population (Ref. 55951).

Biology     Glossary (e.g. epibenthic)

Specimens were collected in a karstic river with fresh, oligotrophic, running water. The adults collected only in the main current at the greatest river depth (5.5 meter); bottom was clear gravel laterally becoming muddy; the juvenile (paratype) was collected in shallow waters, among vegetation (Ref. 55951).

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=0.00977 (0.00442 - 0.02163), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
