Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 16 - 19; Anal spines: 0; Anal soft rays: 16 - 21. Diagnosis: Body moderately deep, belly fairly sharply keeled (Ref. 188). Lower gillrakers 30-40 (Ref. 188). A black or golden spot behind gill opening; upper part of pectoral fin dusky; caudal fin pale yellow with dusky hind margin (Ref. 188). Sardinella rouxi resembles S. maderensis, which has more gillrakers and a grey caudal fin, its tips almost black (Ref. 188). It is distinguished from small S. aurita by having 1 unbranched and 7 branched pelvic fin rays vs. 1 unbranched and 8 branched in S. aurita, and no black spot on hind part of gill cover (Ref. 188).

Sardinella rouxi is found in inshore waters and along beaches, forming schools (Ref. 188).

Estimates based on models

Preferred temperature (Ref. 123201): 24.4 - 28, mean 26.8 °C (based on 66 cells).

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

Bayesian length-weight: a=0.00851 (0.00399 - 0.01817), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Medium.
