Gilt-head seabream, scientifically known as sparus aurata, are found in the Mediterranean Sea and the Eastern Atlantic coasts. Its reaches 70 cm in length and weighs up to 7 kilograms.
The gilthead species is the tastiest among all bream fish and the only species of seabream currently farmed on a large scale. It inhibits both marine water and brackish waters of coastal lagoons. It was effectively reproduced in captivity and intense rearing systems, particularly sea cages, since the 1980s. Adult fish are prepared for spawning by controlling exposure to daylight and temperature. Males fertilize the eggs before floating on the water surface. Eggs then are carried to incubation tanks to hatch 48 hours later. Within 3 to 4 days, the larvae absorb their yolk sac and can start feeding.
