Based on an agreement between Jahad Nasr Hamzeh Company as "the employer" and the Iranian Fisheries Research Organization as "the executor", a project entitled “culture of Huso huso up to 10 kg" was conducted. A total of 600 Huso huso with the average weight of 5000 g were distributed in four 50 m2 circular concrete tanks (4 diameters) with the density of 25 kg/m2 . The experimental system was equipped with aeration. Dissolved oxygen concentration was maintained at 6-7 mg/l. Fish were fed experimental diets composed of 43% protein, 22 % lipids, 16.2% carbohydrates and 22 MJ/kg energy for 12 months. At the end of the first rearing phase (365 d), fish with the mean specific growth rate (SGR) and feed conversion ratios (FCR) of 0.27 and 2.91, respectively reached a weight of 9.06 kg. The highest growth parameters and the best FCR were recorded in spring and autumn. The mean body weight increase (BWI %), specific growth rate (SGR) and feed conversion ratio (FCR) in these seasons were estimated at (0.48, 0.36 % per day), (27.4, 20.13 % during the rearing period) and 1.85 and 1.74, respectively. Results obtained from this project revealed that Huso huso is a prospective candidate for intensive culture in concrete tanks and these results can be developed in many parts of the country.
