Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0; Anal soft rays: 50. Belly with about 29 scutes. Lower jaw projecting, mouth pointing obliquely upward; no hypo-maxilla. Pectoral fin a little longer than head; dorsal fin origin nearer to caudal fin base than to vertical from pectoral fin base by about 2 eye diameters (or behind midpoint of body by about 3 eye diameters); anal fin long, its origin much nearer to snout tip than to caudal fin base.

Either living in rivers or entering rivers from the sea (Ref. 9336).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00386 - 0.01791), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).

Price category (Ref. 80766): Low.
