Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 10; Anal soft rays: 9. Distinguished from its congeners by the unique combination of the following characters: dorsal fin rays 3+7, anal fin rays 3+6, pectoral fin rays 1+14; lateral-line scales 39-41, predorsal scales 12-13; body rather slender, the transverse rows of papillae on snout loosely arranged and very long barbels over 2/3 of eye diameter and body with longitudinal grayish and golden stripes; dorsal side scattered with few irregular black spots; a longitudinal row of grayish black blotches along lateral body; all fins unmarked (Ref. 57944).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00496 - 0.00880), b=3.14 (3.10 - 3.18), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 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 (13 of 100).
