Monitoring of mohammadiye channel water in order to aquaculture purposes
In this survey the Physical and Chemical factors, heavy metals,agricultural pesticides and microbial contaminations were studied in mohammadiye channel extending Eslamshahr, Robat karim and Shahriar cities of Tehran Province during the 2011.Specimens were obtained from 5 different stations .The measured factors were temperature,DO, Cl,HCO3,COD,BOD,CO2,Mg,……. The analysis of Physical and Chemical factors of Mohammadiye channel water showed that except water temperature,all factors in comparison to the standards were at the standard level,So they are suitable for aquaculture. The result of measurements of heavy metals including lead, copper,Iron,Cadmium, Zinc and mercury in spring, summer and fall in comparison to existing standards showed that unfortunately except copper the amount of other heavy metals are higher than standard levels in the most of stations , Lead amounts at stations 2,3,4 and 5 . zinc at stations 1 and 5 , Iron at stations 1,3 and 5 , cadmium and mercury in all stations were higher than the standards for fish culture. The measured amounts of organophosphate and organochlorine pesticides and result of microbial contaminations culture were less than standard levels. Due to mean of water temperature that is high from middle of Spring to the end of summer , It is suitable for culture of warmwater fishes and because of low water temperature in the station No1 It is recommended for culture of coldwater fishes by using of 50-70gr of young fishes .
