Distribution:	Eastern Atlantic: Norway to Morocco, the Canary Islands and Senegal. Reported from Iceland (Ref. 12462). Also known from the Mediterranean and Black Sea.
Diagnosis:	Dorsal spines (total): 8-10; Dorsal soft rays (total): 12-13; Anal spines: 3-3; Anal soft rays: 10-12. Posterior edge of opercle finely serrated, lower edge with strong forward- directed denticles. 2 flat opercular spines. Mouth moderately protractile. Young with some dark spots on upper part of body. Head with cycloid scales above. Vomerine teeth only anteriorly, in a crescentic band.
Biology:	Adults manifest demersal behavior, inhabit coastal waters down to about 100m depth but more common in shallow waters (Ref. 54221). They are found in the littoral zone on various kinds of bottoms on estuaries, lagoons and occasionally rivers. They enter coastal waters and river mouths in summer, but migrate offshore in colder weather and occur in deep water during winter in the northern range. Young fish form school, but adults appear to be less gregarious (Ref. 9987). Feed chiefly on shrimps and mollusks, also on fishes (Ref. 5990). Juveniles feed on invertebrates, taking increasingly more fish with age. Adults piscivorous . (Ref. 59043). Spawn in batches (Ref. 51846). Spawning takes place in the spring near the British Isles, and earlier in its southern range. Eggs are pelagic (Ref. 35388). Marketed fresh or smoked (Ref. 9987). Highly sought by sport fishermen (Ref. 30578). The North Eastern Sea Fisheries Committee (NESFC) sea bass fishery of this species has been certified by the Marine Stewardship Council (http://www.msc.org/) as well-managed and sustainable (http://www.msc.org/html/content_1432.htm)
