Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 10 - 11; Rayons mous dorsaux (Total): 14-16; Épines anales 3; Rayons mous anaux: 7 - 9. Diagnosis: depth of body less than head length, depth 3.0-3.6 times in SL; head length 2.5-2.9 times in SL; interorbital area convex; preopercle angular, 3.6- large spines at the angle, lowermost directed ventrally; posterior nostril slightly bigger than anterior nostril; maxilla reaches nearly to vertical at rear edge of eye; pelvic fin origin below base of pectoral fins; rounded caudal fin; body scales ctenoid (Ref. 89707).

Biologie     Glossaire (ex. epibenthic)

Adults are found on rocky or mud-sand bottom; juveniles have been taken in coastal lagoons and estuaries (Ref. 5222, 57293). In the west African waters, diet comprise of fishes (58%), stomatopods (21%), crabs (10%), and cephalopods (10%). It is a protogynous hermaphrodite. The seasonal migration of the species off the coast of Senegal is influenced by the seasonal upwelling off Senegal and Mauritania. Utilized fresh and smoked (Ref. 9987). Highly esteemed in the market of West Africa (Ref. 5377).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Most females change sex at about 9 kg, but smaller males (of 3 to 5 kg) are occasionally found. Total potential fecundity was estimated to range from 789,436 ova in a 44 cm SL fish of 2.2 kg to 12,589,242 ova in a 87 cm SL fish of 12.6 kg. In Tunisia, sex change occurs at 10 to 13 years (6 to 15 kg, 80 to 110 cm TL).
