    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.

    Description: Genetic diversity of six populations of bartail flathead (Platycephalus indicus Linnaeus, 1758) was investigated using amplified fragment length polymorphism (AFLP). A total of 118 reproducible bands amplified with ten AFLP primer combinations were obtained from 42 fishes that were collected from six different locations in the northern part of the Persian Gulf. The percentage of polymorphic bands was 57.06%. Nei’s genetic diversity was 0.1808±0.2074 - 0.2164±0.1903, and Shannon’s index was 0.2675±0.2949 - 0.3280±0.2727. The results of AMOVA analysis indicated that 66% and 34% of the genetic variation occurred within and among the populations and gene flow was 0.6454. The estimated level of population differentiation as measured by average Fst value across all loci was 0.327. Analyses revealed significant genetic differentiation with low gene flow among the six locations, indicating at least six separate populations of bartail flathead in the northern part of the Persian Gulf.

    Description: Responsible aquaculture is a new concept in Iran but in some countries there are good historical performances. In fact this concept is as the spacial challenge for developing countries in order to improvement of aquaculturist livelihood. In bangladesh, near to 60% of the people, which the most of are villagers, live under the poor line. Developing the NGOs and their activities to reach the responsible aquaculture objectives were so effective, since this activity has been knew as profitable acuaculture and many international workshops, symposiums and conferences have been held in this regard all the world. In this project, a complex of parameters affected on preparing management of warmwater fish farms have been studied with using previous studies and experiments of different countries and executive guidelines of four modules prepared including: -Guidline of preparing of warmwater fish ponds -Guidline of water enrichment and using fertilization in warmwater fish ponds -Guidline of using aeration in warmwater fish ponds -Guidline of stocking method in warmwater fish ponds

The Caspian Sea about 1200 km from north to south on the longest section and an average width of 320 km. Along the coastline around the Caspian Sea is about 6500 kilometers. Caspian Sea is about 78,000 cubic kilometers of water volume that is 44% of stocks of blue lakes around the world. Caspian Sea basin, which is composed of seven major basins of the main watershed from west to east are: juniper, Talsh- Anzali, large Sefidrood between Haraz Sefid and, Hraz- Gharehsou, Nagorno Sv- Gorgan and Atrak in the basin of Aras no limits to the beach. Aras sub-basin is located in the North West and Iran, the second largest sub-basin of the Caspian Sea. Talysh-Anzali on the Caspian Sea basin West and the seventh largest sub-basin of the Caspian Sea. White basin is located in the South East of the Caspian Sea and the extent of the sub-basin of the Caspian Sea. Haraz located in the south Caspian Sea basin and the ninth largest sub-basin of the Caspian Sea. Gorgan is located in the South East of the Caspian Sea basin and the fourth largest sub-basin of the Caspian Sea.
