Identification the useless source of brackish waters for aquaculture in Kerman province

Abstract

This project was carried out with the aim of investigating and identifying brakisk and saline water sources of Kerman province during 2008 to 2009 at city of Ravar-Shahrbabak-Sirjan-Zarand and Rafsanjan. In these cities, there are a lot of salty water sources such as well-river and drainage, due to excessive salinity,they are not suitable for any kind of activity, such as agriculture, drinking and industry. In addition, with the influx of salty water towards freshwaters, the volume of fresh water has also been reduced. The results of this research show that the salinity of these waters varies from 8-150 ppt. In some parts of the province, there are high-water flow agricultural wells (about 70 liters per second) that, in recent years, due to salinization, no crops and gardens (even pistachios) are used for irrigation, and now it is useless and They are not exploited. The results of this study showed that the lowest and the highest temperature of brakisk and saline water sources, regardless of the source of water, varies from 13.5 to 24.5 degrees Celsius. The pH changes in various waters varies from 6. 8 to8.6. Water hardness fluctuated in most sources of salty water at a range of 1650-4800 mg / l. Considering the results of the possibility of culture of rainbow trout,sturgeon,seabream,milk fish,carp,tilapia and artemia in these waters.
