Abstract :

Abstract[1] Due to the lack of adequate surface water resources in arid and semi-arid regions, aquaculture industry has been forced to use underground water resources in these areas. Concerning water quality and resources as the main determining factors in appropriateness of water using for aquaculture activities, this study examined these water resources capabilities in rainbow trout culture through zone classification of water quality (including flumes) by using GIS and Geostatic in Yazd Province. As type of location data was point for water resources, different methods of Geostatic were used in zoning and detecting of suitable areas for aquaculture firstly and finally, appropriate range was divided. Then, qualitative data of flumes in many features such as pH, hardness, salinity and concentrations of elements such as chloride, sodium, potassium, magnesium, calcium, bicarbonate and sulfate were compared with qualitative standards of rainbow trout culture. The results showed that the quality of some water resources is inappropriate for using in rainbow trout culture. * Corresponding Authors; Email: [e-mail]
