المستخلص: A practical experiment on induced spawning is carried out under a control environment, using hatchery tanks of MBRC in Tagura. Gilthead seabream, Sparus aurata (L.), is a eurythermic fish, and is one of the important commercial marine species, cultured for its high economic value, both extensively in brackish water lagoons and intensively in tanks and floating cages in the Mediterranean sea. The experiment has been carried out for 9 months under a control of temperature and photoperiod. Spawning success was achieved from winter to spring season. Production of eggs increased gradually from November 2008 to February 2009. A total of (18456 mls), eggs were obtained during the experimental period, some of them were stocked in separate tank for hatching larvae, but unable to carry out larval rearing due to high mortality (80%). Further study is necessary in terms of survival rate of larvae on experimental level as well as large scale hatcheries.
