Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 13 - 15; Mjukstrålar i ryggfenan (totalt) : 14 - 16; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 10 - 11. Diagnosis: lower pharyngeal bone about as long as broad, and with anterior lamella shorter than toothed area; median pharyngeal teeth broadened when compared to the lateral teeth; 5-6 series of scales on cheeks; 4.5-6 scales between first dorsal fin spine and upper lateral line; dark vertical bars broader than lighter inter-spaces (Ref. 53405).

Occurs only in larger rivers with rocky substrates, not found in smaller creeks; not specialized, but prefers a herbivorous diet; pair-bonding, biparental open substratum spawner holding very large territories; might spawn throughout the year (Ref. 52307).

Estimates based on models

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

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).
