Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 8; Rayons mous dorsaux (Total) : 16; Épines anales: 3; Rayons mous anaux: 14. Body silvery. Naked head; with nuchal spine. Mouth strongly oblique; nostrils situated above eyes (Ref. 48635). Protracted mouth pointing upward; Tip of maxilla reaching well below level of lower margin of eye. Body depth twice or slightly more than standard length. Lateral line ending before dorsal fin.

Schooling species found in shallow waters, usually near the bottom (Ref. 30573). Occasionally enters brackish waters (Ref. 4833, 48635). Swims in loose groups (Ref. 48635). Feeds on zooplankton including copepods, mysids, and larval fishes and crustaceans (Ref. 11441). Sold fresh and dried salted; also used for fishmeal.

Estimates based on models

Preferred temperature (Ref. 123201): 22 - 28.5, mean 27.2 °C (based on 1101 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01202 (0.00915 - 0.01580), b=3.00 (2.93 - 3.07), in cm total length, based on LWR estimates for this species (Ref. 93245).

Niveau trophique (Ref. 69278): 2.8 ±0.27 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (K=1.20-1.50).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).

Catégorie de prix (Ref. 80766): Medium.
