Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 2; Radios blandos dorsales (total) : 5 - 7; Espinas anales: 0. Diagnosis: adipose fin rayed in adults, 1st ray forming a spine (not visible in juveniles); adipose-fin rays becoming visible at sizes of 90-100 mm SL, and the spine at 200 mm; dentition very well developed: premaxillary tooth plate broad (38-45% of head length), palatine dentition consisting of an elongate vomerine plate and of a dermo-palatine plate in young individuals (60-70 mm SL); palatine tooth plates narrow and long with much weaker dentition; nasal barbel long, reaching at least to anterior part of orbit; maxillary barbel very long, exceeding at least the anterior part of dorsal fin and often reaching to adipose fin; caudal-fin lobes marked by a dark band; cranial bones well developed; length of occipital process usually less than 1.4 times its width (Ref. 57126).

Inhabits rivers (Ref 4967). Feeds on crustaceans, insects, mollusks and fish (Ref. 28714).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00786 - 0.02658), b=3.04 (2.88 - 3.20), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nivel trófico (Ref. 69278): 3.1 ±0.43 se; based on food items.

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (59 of 100).
