Short description Morphology | Morphometrics

Dorsal spines (total): 9 - 10; Dorsal soft rays (total): 12-14; Anal spines: 3; Anal soft rays: 10 - 12. Diagnosis: elongate fish with 2 separate dorsal fins and a rather deep caudal peduncle; vomerine teeth patch anchor-shaped, with the posterior teeth extending to the midline of palate; scales on interorbital space ctenoid; opercle with 2 flat spines; lower preopercular margin with large, forward-pointing spines; caudal fin moderately forked; scales small (Ref. 57391). Coloration: silvery grey, back bluish in life; juveniles and adults with small dark markings scattered over back and sides; a very distinct black spot on opercle (Ref. 57391).

Biology     Glossary (e.g. epibenthic)

Coastal species (Ref. 4197), found in coastal marine and brackish waters (Ref. 57391). Occurs on various kinds of bottoms, including sand, muddy sand and rocks; occasionally occurring in rivers (Ref. 6916, 57391). Also capable of living in hypersaline habitats (Sine Saloum in Senegal)(Ref. 57391). Feeds mainly on shrimps and mollusks, also fishes (Ref. 5990).

Estimates based on models

Preferred temperature (Ref. 123201): 13.3 - 20.7, mean 17.3 °C (based on 39 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7656   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00429 - 0.01066), b=3.06 (2.92 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.65 se; based on food items.
Generation time: 7.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.07-0.16).
Fishing Vulnerability (Ref. 59153):  High vulnerability (55 of 100).
Climate Vulnerability (Ref. 125649):  High to very high vulnerability (74 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 35.4 [3.9, 188.9] mg/100g; Iron = 0.815 [0.282, 2.003] mg/100g; Protein = 20.5 [19.2, 21.9] %; Omega3 = 0.345 [0.187, 0.624] g/100g; Selenium = 10.5 [3.3, 29.4] μg/100g; VitaminA = 9.83 [2.35, 42.99] μg/100g; Zinc = 0.716 [0.328, 1.624] mg/100g (wet weight); based on nutrient studies.
