Short description Identification keys | Morphology | Morphometrics

Body somewhat elongate; mouth sub-terminal; cephalic plate prominent, granulated, and rough; pre-dorsal plate narrow; pre-maxillary teeth villiform; vomerine teeth lacking; palate with molariform teeth set in two separate sub-oval plates; inner edge of pectoral spine coarsely notched; caudal fin lobes long, thin, and pointed, about the same length as the head; body dark brown; belly white; flanks silvery blue (iridescent); fins dark or black; barbels dark brown (Ref. 55763).

Found in marine, brackish and fresh waters (Ref. 9271). Rarely consumed due to its small size (Ref. 9271).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00347 - 0.01656), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.8 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).

Price category (Ref. 80766): Medium.
