Description:
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.
