Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 11; Spine anali: 1; Raggi anali molli: 11; Vertebre: 37. This species is distinguished from all its congeners by the following set of characters: D1 absent; D2 I/11; A I/11; pectoral fin rays modally 16 and with one upper, very short free soft ray; vertebral count 16 + 21 = 37; head and body with many rounded light creamy white spots above creamy yellow background (Ref. 86740).

Found among gravels at the rapids which are in the most lower reaches in the freshwater area on the river (Ref. 86740).

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 (0.00444 - 0.02153), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
