Meagre

Argyrosomus regius has a relatively large head with quite small eyes, the large mouth is at the terminal position and it has an elongated body. The lateral line is easily seen and extends all the way to the caudal fin. The rear dorsal fin is much longer than first one which has nine rays. The first ray of the anal fin is short and spiny while the second is very thin. The swim bladder contains several branched appendages which are vibrated to make a grunting sound which can be heard from up to 30m away and this grunting is produced by the males during the spawning season. The body colour is pearly-silver, with bronze traits dorsally. The fin bases are reddish brown and mouth cavity yellow-gold or salmon pink. The scales are large and every fourth scale is set at a different angle from the rest. It can reach up to 2.3 m (7.5 ft) in total length and 103 kg (227 lb) in weight.

Argyrosomus regius is found in the eastern Atlantic from Norway to DR Congo, including the Mediterranean Sea and the Black Sea. It has colonised the Red Sea by migrating through the Suez Canal, an anti-Lessepsian migration. It is rare in the relatively cold, far north of its range, including off the British Isles (three records) and Scandinavia.

Argyrosomus regius is a demersal, oceanodromous fish which is found in inshore waters and on the continental shelf, it can occur close to the bottom as well as in surface and mid-waters. The adults prey on grey mullet and clupeids such as sardines which are actively pursued in open water. The adults gather in inshore waters to spawn during spring and summer. The juveniles and subadults prefer estuaries and coastal lagoons, and the health of recruitment into the adult population is possibly determined by the availability of these habitats. These fish are migratory, at all ages, migrating along shore or between offshore and inshore waters in response to temperature changes. A. regius feeds on fishes and swimming crustaceans and mostly occurs over sand, close to rocks, at depths of 1–200 m (3.3–656.2 ft), but commonly found at 15–100 m (49–328 ft).

Argyrosomus regius is fished commercially using trawls, long lines, and hand lines. It is also a sport fishing quarry species. Specimens of 1.8 m in length and over 50 kg in weight which were landed in Portugal in 2002 fetched over €200. The main meagre fisheries are currently in Mauritania, Morocco, and Egypt and these account for over 80% of the annual world catch of around 10,000 tonnes. The European fisheries are comparatively small and are on the Atlantic coasts of Spain, Portugal and France with annual catches of 800 t in France, 400 t in Portugal and 150 t in Spain.
