Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 61 - 69; Épines anales: 0; Rayons mous anaux: 48 - 58; Vertèbres: 39 - 40. Dorsal origin above posterior part of eye. Caudal rounded at edges. Pectorals bluntly pointed.
Adults feed on hydroids, worms, mollusks, and brittle stars (Ref. 6885). Marketed frozen and eaten fried, microwaved and baked (Ref. 9988).
Each individual spawns from 8 to 11 batches (Ref. 39301). Spawning occurs primarily in shallow water but for large females spawning may take place in waters to a depth of around 50 m (Ref. 119537). Undergoes spawning and feeding migration (Ref. 119537).
