Evaluating the factors affecting on Profitability of Trout Farm Fisheries (Case study: Ilam Province)

There are many rivers and springs with enough water supplies in Ilam province, which provides good places for establishing farm fisheries in the region. The objectives of this study are: (i) to examine the profitability of Trout farm fisheries, and to distinguish between successful and less-successful farms and (ii) to specify factors affecting profitability of success using profitability indicators and Mann-Whitney test. Results indicate that age, education, location, participation in training workshops and growing period have significant impacts on success of the farms. The total revenue to total cost (TR/TC) and rate of equity (ROE) of the farms on average are 1.07 and 5.88 for less-successful farms and 1.33 and 25.9 respectively for successful farms. The price margins are 92% and 76% for the less- successful and successful farms respectively. The results also indicate that factor productivity of large farms increases as size of the farms increases.
