Abstract

Aquaculture of marine fish, especially cage culture, is one of the common methods of mariculture in the world, which has been considered in recent years in Iran. One of the species that has been considered for cage culture in Iran is an Epinephelus coioides, which biotechnology of its reproduction was achieved in Bandar Imam Khomeini marine fish research station. In a study carried out at Bandar Imam Khomeini marine fishes research station, it was observed that this species can be stocked with a stocking density of 30 pieces m3 (with an initial weight of about 50 g) and using pellet food and or trash fish from the July to late of the November in cages made of simple raw materials. Orange spotted grouper juveniles were stocked in the floating cages of 27 m3 (3 × 3 × 3 meters) and propagated for 143 days, then harvested with an average weight of 523.7 ± 28.0 g and 317.5 ± 22.1 kg / 27 m3 (11.8 kg/m3) in treatments that fed trash fish and pelet diet, respectively. The results of this study indicated that cage culture of this species in the khuzestan region is justifiable and cost-effective. Moreover, these results suggesting that higher weight gain can be achieved by extending the culture period from the April to the late of March.
