Abstract
|
The present study was conducted to mapping the groundwater quality of Yazd-Ardakan
plain to find the appropriate areas for the integrated aquaculture and agriculture. An
integrated analysis of spatial and filed data from multiple sources including cations,
anions, hardness, alkalinity, pH, salinity, dissolved oxygen, carbon dioxide, and the
temperature was performed in 37 agricultural wells. The geographic information system
was carried out to prepare the different data layers and classified based on the standards
for warm water (Carps) and cold water (Trout) aquaculture. The comparison of maps
indicated that concerning the obtained data, it has no possibility to explore a unique
region with the highest desirability towards the followed purpose. Furthermore, the
northern parts of the study area were dominantly illustrated more appropriate for the
culture of cold-water fish, accordingly. The main limiting factors for the warm-water
fish were sulfate and magnesium ions in the water resources accounted for 118-354
mg/L and 1132-3085 mg/L, respectively. Conclusively, the agri-aqaculture
development strongly depended upon the applied aeration equipment to reduce
restricting ions.
