Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 14; Anal spines: 0; Anal soft rays: 17 - 26. Belly with 16 to 18 (usually 17) + 10 to 13 (usually 11 or 12), total 26 to 32 (usually 28 or 29) scutes. Anterior arm of pre-operculum with a fleshy triangular area above, not covered by third infra-orbital bone (see N. come). Edge of lower jaw strongly flared outward. Pectoral axillary scales absent. Hind edge of scales toothed. A faint band on flank.

Occurs in rivers, but no indication whether it descends to estuaries. A filter-feeder. More data needed.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00415 - 0.01826), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).

Price category (Ref. 80766): Low.
