Analysis of factor costs contribution change for fingerling production of Kutum fish (Rutilus frisii kutum Kamensky, ۱۹۰۱) in Iran

 Contribution change of factor costs analysis may help managers in decision making and in adjusting to changes. Over the last two decades, production and enhancement of kutum fingerlings have increased in Iran, reaching to more than ۲۲۹ million fingerlings by ۲۰۰۵, but declined to ۱۸۷ million from ۲۰۰۵ to ۲۰۰۸. Over the years ۲۰۰۲-۲۰۰۶, a study of fingerling production costs for kutum fish was carried out. For this purpose, a questionnaire was prepared and filled out by an expert team using data available in kutum hatcheries for fingerling production and other related departments in Iranian Fisheries Organization. Among various expenditures, the contribution cost of labor with the greatest share averaged almost ۴۰% of total costs, followed by feed and fertilizer which averaged more than ۱۵%. Results show, in average, the production cost of a single kutum fingerling was ۱۰۰ IR Rials (US ۰.۰۱), which varies from almost ۳۷ IR Rials in ۲۰۰۱ to ۱۳۰ IR Rials (US ۰.۰۱۴) in ۲۰۰۴ and ۱۵۷ IR Rials (US ۰.۰۱۷) in ۲۰۰۵. Yearly growth of a single fingerling was averaged more than ۵۰% from ۲۰۰۱-۲۰۰۵. The results clearly indicated that over the years ۲۰۰۱-۲۰۰۵ the contribution cost of labor and "feed and fertilizer" declined, but it increased for "water and energy" and Miscellaneous. Overall, the costs sensitivity analysis of hatcheries production of kutum fingerling shows labor is the most sensitive, and a ۵۰% decrease of this item, decreases the total cost by almost ۲۰%.
