Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 14 - 16; Espinhos anais: 0; Raios anais moles: 17 - 19; Vértebras: 38 - 39. Diagnosis: Body slender or moderate, depth about 25% of standard length; scutes a little behind isthmus, very strongly keeled, 9-10 pre-pelvic and 7-9 post-pelvic scutes; lower jaw very slightly projecting, toothless; no teeth on premaxillae or maxillae; posterior supra-maxilla as deep as maxilla blade and with long slender anterior shaft; lower gillrakers 20-23; pelvic fin with 1 unbranched and 6-7 branched rays, its insertion just below dorsal fin origin; anal fin rays 17-19; scales in lateral series 34-35 (Ref. 188, 94752). It differs from Nannothrissa parva in having fewer gillrakers, 20-23 vs. 24-31, fewer anal fin rays, 17-19 vs. 20-23, and fewer scales in lateral series, 34-35 vs. 35-40 (Ref. 188, 94752).

A lacustrine species in acid waters (Ref. 188).

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=0.00912 (0.00433 - 0.01920), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).

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

Categoria de preço (Ref. 80766): Low.
