The Study and Feasibility of Down Stream Area of Yamchi Dam for Aquaculture Development in Ardabil Province

The research conducted for finding of aquaculture potential and appropriate areas of Yamchi dam downstream river and estimate of its production in 2010-2012. This research done by using of available information and data obtained from the monthly and seasonally sampling. Results showed that river access routes of left side to right were more suitable. The maximum distance of infrastructure facilities was one kilometer. Climate and weather data suggests that downstream area Yamchi dam was not suitable for warm water species aquaculture, while it was ideal for coldwater aquaculture. Also, physical and chemical results showed that almost all of the factors were suitable for growing trout. Heavy metals amounts were measured in the standard limit and iron, cupper, zinc, lead, chromium, cadmium and nickel had highest values, respectively. Bacillariophyta branch abundance of phytoplankton was dominant as showed suitable water quality. Benthos investigation demonstrated that the aquaculture activities is acceptable. In ichthyology studies identified 5 species Cyprinidae and 1 species Nemacheilidae family. Investigation of available underground wells and geophysical studies showed that alluvium area is made up from two parts of clayey surface ground and underground with good permeability and the lower part is affected from the upper part. In areas where both part of the alluvium formed there is a water layer about 20 to 30 meters thick as it is possible to build wells. But in areas without lower part faced with unreliable surface water layer that affected from river flows. Totally, varius method suggested for trout culture include of race way, octagonal pond and semi-recircultaion. In the present condition of Yamchi river the amount of trout production is predicted at least 65 ton by race way to maximum 1750 ton by semi-recircultaion method. Whiles, if 2 cubic meters of water from Yamchi dam outlet allocated to aquaculture can be predicted at least 580 ton by race way to maximum 4000 ton by semi-recircultaion method.
