Abstract :

Growth of population and economic-social needs of human being led to impressive growth of industries including aquaculture as an important source of protein needs in recent decades. This development which is usually associated with lack of environmental impact studies leads to environmental degradation in many countries. Therefore, this study was conducted to evaluation of ecological potential of Kabgian basin for aquaculture. In so doing, texture, depth and erosion of soil, slope, temperature, pH and water flow, stone, sensitive habitats, protected areas, conservation value of species and ArcGIS 10.2 according to 'Makhdoum Aquaculture Model' were used for site selection of fish farming ponds along the Kabgian River. The results showed that from 192 ha extent of the study area, 78.7 ha in the vicinity of Botari village was suitable for the development of aquaculture industry. As regards spatial distribution of fish farming ponds along the Kabgian River is not in a good condition and just focused on a specific part of the river, therefore, self purification potential of river will be decreased. So to reduce of environmental impacts of aquaculture on the water quality of Kabgian River, move the fish farming ponds to suitable areas for aquaculture development is recommended.
