Argyrosomus regius, also known as the meagre, croaker, jewfish, shade-fish, sowa, kir, corvina, salmon-bass or stone bass, is a species of fish of the family Sciaenidae.

[2] Argyrosomus regius was first formally described in 1801 as Perca regia by the Spanish diplomat, naturalist, lawyer and historian Ignacio Jordán Claudio de Asso y del Rio with the type locality given as La Rochelle in Charente-Maritime on the Bay of Biscay coast of France.

[6] 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 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.

[1] Large schools of A. regius occur around wrecked ships that were deliberately sunk to create new habitat for a number of commercially caught species of fish.

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).

[7] 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.
