Biology

Argyrosomus regius or meagre is a fish of the Sciaenidae family. It has a similar form to a European seabass, with a pearly-silver coloration and a yellow-coloured mouth. Length can range from 4050 cm to 2 m long, with weights up to 55 kg. Distributed across Eastern Atlantic: Norway to West Africa, including the Mediterranean and western end of Black Sea and Sea of Marmara. Also in lakes of Nile delta and Bitter Lakes to Gulf of Suez; has migrated to the Red Sea via Suez Canal. The biggest fish are found along the coast of West Africa. In Senegal, in the bay of Dakar seems to be the southern limit of the species; big schools of meagre are found around wrecked ships that were sunk to create habitats for several commercial species. Adult meagre stay in deeper water (to 300m) in winter and move inshore in mid-April and enter estuaries to spawn (anadromous migration). During the spawning season, males produce a typical deep sound, by pushing their abdominal muscles against the gas bladder. A 1.2 m female produces about 800 000 eggs, spawning occurs at 17-22 degrees C. Juveniles stay in shallow water and eat small fish and crustaceans . When they reach 30-40 cm, they feed on pelagic fish and cephalopods, the adult diet.

Production method

Open net pen

Meagre are farmed in open net pens in the sea. These are floating cages suspended in the sea and held in place by moorings underneath the cages. Water flows through the cages which are made of strong netting that also allow waste to fall through to the sea bed below.
