Behaviour and life history
Argyrosomus regius is a
The newly hatched juveniles leave the estuaries where they spend the first few months at the end of summer and move into coastal waters with depths between 20 and 40 m (66–131 ft) where they spend the winter months. In the following spring they return to their estuarine feeding areas from the middle of May. Water temperature is the most important factor that determines the trophic migration and reproduction of meagre. An adult female A. regius measuring 1.2 m (3.9 ft) in length produces about 800,000 eggs and spawning occurs when the water temperature is 17–22 °C (63–72 °F). The juveniles eat small demersal fish and crustaceans switching to pelagic fish and cephalopods once they grow to 30–40 cm in length.[5]
Fisheries
Argyrosomus regius is fished commercially using trawls, long lines, and hand lines. It is also a sport fishing quarry species.[1] Specimens of 1.8 m in length and over 50 kg in weight which were landed in Portugal in 2002 fetched over €200.[7] 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.[7]
Aquaculture
The farming of Argyrosomus regius is still rather experimental and involves intensive production, in land-based tanks and sea cages. There are few facilities established mainly in southern France where they are in the Camargue, Cannes, and Corsica, in Huelva, Spain, and at La Spezia and Laguna di Orbetello in Italy.[5] It is also produced in large quantities in Turkey.[citation needed]
