Habitat
The brown meagre is found at depths between 5m and 200m,[ mainly over rocky and sandy substrates and the young enter estuarine environments.]
Description
The brown meagre is between 30 and 40 cm in length but can grow to 60 cm. It has a flat belly and its strongly arched back which give it an easily recognisable shape, the body is laterally compressed and the large, horizontal mouth reaches the level of the eye and contains villiform teeth. The anal and pelvic fins are black with an anterior white border. Both dorsal fins and the truncate caudal fin, are yellow with a black border. The body is grey with flashes of gold and silver. The scales are ctenoid

Biology and behaviour
It is a rather nocturnal fish but it can occasionally be found during the day among beds of sea grass and on rocky bottoms in the vicinity of caves or large crevices where it can shelter. This species is social and lives in small groups.[ It feeds off the small fishes and crustaceans. They are capable of creating sound using some muscles under their well developed swim bladder. This is their way of communication since they have a very good hearing ability.] They can manage their buoyancy perfectly.[ The spawning period is from March to August in the Mediterranean.][

Fisheries
The brown meagre is a commercial species throughout the Mediterranean basin and has been over exploited by fishing practices. It is fished mainly by spear fishing, trammel nets, and gill nets and is heavily exposed to fisheries during spawning aggregations at the mouths of estuaries.[
