Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 9 - 10. Body all silvery and translucent with a dusky midlateral band. Back margin evenly dark. Membrane between 2nd and 3rd dorsal spine blackish. Mouth strongly oblique. Margin almost straight from the origin of the 1st dorsal snout.

Common in brackish waters near river mouths where it occurs in schools; sometimes found in upper streams (Ref. 559). Mainly marine but enters rivers (Ref. 4967).

Estimates based on models

Preferred temperature (Ref. 123201): 24.9 - 29, mean 28.1 °C (based on 882 cells).

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

Bayesian length-weight: a=0.01230 (0.00666 - 0.02273), b=3.00 (2.84 - 3.16), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Assuming Fec > 10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
