The Comparison of two species of the endomic important agarophyts in Iranian South Coasts to aquaculture; Gracilaria corticata (J.Ag.) J.Ag. & Gracilariopsis longissima (S.G.Gmelin) M.Steentoft, L.M.Irvine & W.F. Farnham

According to the different researchers and subjects were done about seaweeds, but, suitable species have not introduced to aquaculture. So, in this researching were comparison two important agarophytes Gracilaria and Gracilariopsis and was selected species that has suitable aquaculture factors. These aquaculture factors as following, quantity and quality of agar, required natural sources and easy access to stock assessment in the environment, possible of culture and adaptation, growing in more large sizes and speedy or increasing of production in per unit. sampling carried out Gracilaria and Gracilariopsis from intertidal Coasts of Sistan and Baluchestan and Hormozgan Provinces respectively from 2012 to 2014. The samples were transferred to the offshore Fisheries Research center of Chabahar and prepared for Extraction of agar. The results were showed that the average in one Kg of wet weight applied about 125 gr. Dry weight and from 100 gr. Dry weight applied 19.83 and 13.03 gr. gel powder from Gracilaria and Gracilariopsis respectively. At least, Gracilariopsis were selected for aquaculture.
