Gilt-head bream
The gilt-head bream (Sparus aurata), also known as the gilthead, dourade, gilt-head seabream or silver seabream, is a species of marine ray-finned fish belonging to the family Sparidae, the seabreams or porgies. This fish is found in the Eastern Atlantic and the Mediterranean. It is a highly esteemed food fish and an important species in aquaculture.
The gilt-head bream was first formally described in 1758 by Carl Linnaeus in the 10th edition of Systema Naturae with its type locality given as the Mediterranean and Venezuela (although this has now been shown to be a specimen of Calamus). It is the only species in the monospecific genus Sparus. The genus Sparus is placed in the family Sparidae within the order Spariformes by the 5th edition of Fishes of the World. Some authorities classify this genus in the subfamily Sparinae, but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.
The gilt-head bream has the genus name Sparus which derives from sparos and Ancient Greek name for this species. The specific name, aurata, means "gold", an allusion to the gold band on the intraorbital part of the head.
The gilt-head bream is found in the northeastern Atlantic and the Mediterranean from Great Britain and Ireland to possibly as far south as Senegal, including the Canary Islands. It is found around Madeira but these are escapes from aquaculture. It also occurs throughout the Mediterranean and in the southern and western parts of the Black Sea.
This species is found over sandy substrates and in seagrass beds at depths between 1 and 150 m (3 ft 3 in and 492 ft 2 in), with adults in deeper waters than juveniles, the young fish typically going no deeper than 30 m (98 ft). It is a euryhaline species that will enter brackish waters.
The gilt-head bream has a deep body, with a large, deep head which has its relatively small eyes placed high on the head. The diameter of the eyes is shorter than the length of the snout. The cheeks are deep and covered in scales but the preoperculum has no scales, although the operculum is scaled. It has a long-based dorsal fin which is supported by 11 robust spines and 13 or 14 branched soft rays. The anal fin is short based and is held up by three spines and 11 or 12 branched soft rays. It has large and robust teeth in the jaws with four to six large, pointed canine-like teeth in the front the jaws with 2 to 4 rows of blunt, round teeth laterally. It has a blue-grey back, the sides are silvery with a large dark spot behind the eye, it is red along the margin of the operculum and there is a golden bar on the head between the eyes.
This species has a maximum total length of 70 cm (28 in), although a standard length of 35 cm (14 in) is more typical, and a maximum published weight of 17.2 kg (38 lb).
The gilt-head bream feeds mainly on shellfish, but also some plant material
