Contribution of the production factors, production costs during the years 2000-2004, and means for increasing the productivity and profitability of sturgeon hatcheries in Iran were investigated by compiling and analyzing the available information, including the documents available in enhancement offices. We designed a questionnaire covering economic and ecological aspects of the activity and distributed it to an aquaculture related expert team. Different sections of the Iranian Fisheries Organization, specially, accounting, budgeting and stock. The results showed the cost of labour and salary comprised 38-56% of expenditures whereas costs of feeding and fertilizer were found to be 4-14%. The maintenance cost was assessed as 4-8%, fertilized eggs cost was 6-35% and depreciation cost was 10-12% of total expenditures. The production cost of a single sturgeon fingerling in Iran was 937-2028 Rls over the 2000-2004. The cost of labour and salary had a large share in total expenditures, somewhat caused by the centers not being active for six months each year. Engaging the labour force with other activities such as cultivation of indigenous and exotic surgeon brooders might be expected to reduce the total costs. With increase in price of caviar in recent years, the price of fertilized eggs has also increased to 35% of total expenditures. It seems cultured sturgeon brooders might fill the gap left by wild brooders inaccessibility in coming years of wild sturgeon.
