Short description Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 13-15; Anal spines: 3; Anal soft rays: 7 - 8. Body is slender; the head profile slightly convex; lips not thickened; 2 pores and a central groove under the chin. No antrorse spine before the dorsal fin origin; a deep notch between the spinous and the soft-rayed portion of the dorsal fin. Color is generally silvery with a golden tint on the sides; the upper operculum olive-yellow; the snout dusky, overlain with yellow. Young specimens have 7-11 vertical bands on the upper sides; older ones with bands formed by spots aligned in vertical rows.

Biology     Glossary (e.g. epibenthic)

Inhabit turbid inshore waters with sandy to muddy bottoms to a depth of 75 m. Enter estuaries, may tolerate water with low salinity. Often associated with inshore wrecks (Ref. 4332). Feed on crustaceans and fish (Ref. 5213, 48635). Spawners form shoals near river mouths during the winter. Good food fish (Ref. 2799).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00898 - 0.02799), b=3.00 (2.85 - 3.15), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.51 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.25-0.57).
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
Price category (Ref. 80766):   High.
