Aquaculture Potentials Investigation of Yamchi Dam Down Stream Areasin in Ardabil Province

Abstract

The research conducted for finding of aquaculture potential and appropriate areas of Yamchi dam downstream river and estimate of its production in 2010-2012. Yamchi dam is located at 25 kilometers of southwest of the Ardabil city. This research done by using of available information and data obtained from the monthly and seasonally sampling. After evaluating of Yamchi river potential and its marginal lands, suitable locations for aquaculture determinated and theirs production was calculated at each site. Totally, 3 areas selected for trout aquaculture and varius method suggested including 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 semirecircultaion method. Whiles, if 2 cubic meters of water from Yamchi dam outlet is provided to aquaculture, it will be predicted at least 580 ton by race way to maximum 4000 ton by semi-recircultaion method
