    An economic analysis of Indian White shrimp (Fenneropenaeus indicus) production in southern provinces of Iran (2018)
    Details
    Publication Date: 2021-05-19
    Description: We studied production costs,factor costs and profitability of shrimp farming in the four southern coastal provinces of Iran during the year 2000. A comprehensive questionnaire was used for data collection. A number of 144 farms were randomly selected, classified and analyzed. An expert team comprising an economist, statistician and shrimp aqua-culturist completed the questionnaire, while referring to all selected farms. Results showed that shrimp larvae stocking density averaged 224966 per hectares and the shrimp production averaged 169kg/ha. On average, food, PL and labour costs per hectare were found to be Rials 10000, 6000 and 2000 respectively. In the year 2000, the average profit for the four provinces of shrimp farming was 9555 Rials per kg. of cultured shrimp. Hormozgan province had the highest profit with 20092 Rials per kg and Khouzestan province had the lowest with 4576 Rials per kg of the cultured shrimp.

    Cost factor analysis of Caspian salmon (Salmo trutta caspius Kessleri, 1877) fingerling production and release in Iran (2018)
    Details
    Publication Date: 2021-05-19
    Description: Iran contributes to the stock enhancement of several economically valuable fish species, including the Caspian salmon, S. trutta caspius, by producing and releasing millions of fingerlings into the sea. This work was conducted to determine the production costs of the Caspian salmon fingerlings in the years 2002 and 2003. For this purpose, a questionnaire was prepared and filled in by an expert team using data available in the Kelardasht Caspian Salmon Hatchery and other related departments. Among various expenditures, on average, cost of labor (52%) and cost of feed (16%) had the greatest share. Results showed the average cost of production and release of a single fingerling in Iran was IRRls 6,685, (US$ 0.84) over the 2002-2003. The cost sensitivity of hatcheries production of the Caspian salmon shows that labor cost is the most sensitive, and a 50% increase in the cost of this item increases the total coast by more than 25% followed by feed cost.

    Study on Economic Aspects of Tilapia Culture in Iran (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The study on economic aspects of tilapia culture in Iran is a subproject of a comprehensive project on introduction of tilapia to central regions of the country. Two types of red and black of the exotic tilapia were imported from Indonesia in 2009 for research and were transferred to the research center of Bafgh. Since tilapia has capabilities in aquaculture such as resistance to diseases, fast growth, tolerance to high intensity, growth in freshwater, brackish water and in saline water, also ability to grow in pond, cage and aquaculture tanks, so it is likely that it’s production be of economic advantages. Therefore the present study looked at economic aspects of raising tilapia. The factors examined were feed expenditures, wages, fertilizer spending, costs of fish fingerlings, and pond preparation in two treatments of black and red tilapia in 0.45 hectare earth ponds, 3m2 aquaculture tanks with two replicates. Results of data analyses showed that benefit of each pond for black tilapia would be about 5968763 Rials. For red tilapia this amounted to 5939696 Rials. On total the benefit for black tilapia pond culture was 11940444 Rials while this for red tilapia was 11879392 Rials, so we can conclude that pond culture of tilapia is beneficial. Culture cost of black tilapia in tanks with 57 Kg outcome, was 2540600 Rials. Accordingly the cost of each kilogram of fish is 44572 Rials, so with 20 percent benefit, the price for each kilogram is 53485 Rials. Also for producing 37 kilograms red tilapia in tank some 2531500 Rials was expended. Each kilogram red tilapia cost 68419 Rls to produce which is much more than other cultured fish and if we expect 20 percent benefit the price of each kilogram of red tilapia would be 82103 Rls. So it is concluded that tank fish culture of tilapia would not be beneficial and economically speaking there would be no point to raise tilapia this way.

    Identifying the main factors affecting home consumption attitude to farmed fishes among Tehrani households (2018)
    Details
    Publication Date: 2021-05-19
    Description: Using reference books, monitoring buyers behavior and interviewing the experts, the effective parameters on home consumption behavior of farmed fish were identified and compiled as a questionnaire. After the reliability and viability evaluation the questionnaire was filled randomly in the spring of 2008 for 295 households of different localities in Tehran. The allocation of questionnaires was conducted based on the proportion of population in each locality. The degree of importance of effective parameters and their priority were calculated by Friedman test. The results showed that, quality, taste, smell and protein content of grocery basket are the most important purchasing factors among Tehrani households. However, those who use only farmed fish or those who do not use fish at all, after quality, smell has the highest importance, and in the fourth priority, instead of protein content of grocery basket, fish bone has higher effect. We suggest that to improve consumption of farmed fish, apart from quality, the strategies of deodorizing, taste improvement and decreasing fish bones, shall be taken into consideration during harvest, transport and fish processing.
