Short description Morphology | Morphometrics

Anal soft rays: 16. Body moderately compressed (Ref. 56505). Head width 17.5-20.5 % of SL (Ref. 56505). A single pair of ovoid vomerine tooth patches (Ref. 56505). Dorsal surface of head and body uniform gray to grayish brown, upper third of head and body darkest, gradually fading to a lighter color along middle third of head and body; lower third and ventral surfaces of head and body dirty white (Ref. 56505). Adipose fin gray, dorsal-fin rays gray, fin-rays of all other fins with scattered gray melanophores (Ref. 56505).

Caught with stake traps, shore seines and bagnets, also on hook and line. Common in rivers and lakes (Ref. 3876), also found in estuaries (Ref. 5213)

Estimates based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00423 - 0.01964), b=3.04 (2.86 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.7 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): High vulnerability (63 of 100) .

Price category (Ref. 80766): Medium.
