Culture of sturgeon species is of great economic and ecological importance for those countries such as Iran whose natural stocks have declined. This species has shown a good growth performance in many types of production systems and in tanks with different sizes. Recently, sturgeon species is also offering good prospects for aquaculture in north of Iran, including: Guilan, Mazandaran and Golestan provinces. Several species of sturgeon are now considered attractive candidates for whole-cycle production in Iran. Production analysis may help manager of a sturgeon farm in decision making and in adjusting to changes. Economic assessment provides a basis not only for decision making among farm managers but also for formulating government aquaculture policies. Over the period 2006, based on previous experiments with cultured cam, shrimp and trout farming, total costs, total income, profitability and the contribution of production costs for sturgeon farming were determined by completing questionnaires. Among the various expenditures in the year 2006, labor costs had the greatest share and averaged 25% of the total costs. Feed costs averaged more than 17% of the Costs and fingerling costs averaged 10% of the costs. Results show, on average, total cost per kg production of sturgeon was IR Rials 40,587 (US$ 4.51) in 2006. Total income per kg production of sturgeon meat averaged IR Rials 68,125 (US$ 7.57), and profitability per kg production of sturgeon meat also averaged IR Rials 27,944 (US$ 3.11). The results suggest that farmers are doing more efficiently and have better conditions in Mazandaran, resulting in higher farm income per kg, followed by Guilan province.
