%X Abstract :Measurements were made on 12 water quality parameters (pH, TN, TP, CODMn, Cu, Zn, Pb, Cd, Hg, oil, volatile phenol and non-ionic ammonia) of a Large amount of freshwater fish breeding waters in Shaanxi Province during 2008and 2009, with Comparison of single-factor and pollution index methods evaluated those parameters, and investigated the situation of aquaculture. The results showed that:The breeding water of a Large amount of freshwater fish in Shaanxi was polluted by the pH, TP, TN and CODMn,which the pollutant extent exceeded the range of 70% in two years, the load ratio accounted for 89.5% and 80.8%; non-ionic ammonia is the most important pollutants, its individual pollution index I (20.2,5.80) and the load ratio Q (57.37%, 27.70%) are ranks first, followed by TN (I: 4.69,5.28; Q: 13.3%, 25.2%), TP (I: 4.05,4.13; Q: 11.5%, 19.7%) in two years monitoring. Hg, Cu, Zn, Pb exceeded small; oil, volatile phenol and Cd in the monitoring of the waters were not exceeded. The monitoring of all parameters were no significant difference (P>0.05) between 2008 and 2009 years. Beware of non-ionic ammonia poisoning, carried out TP, TN pollution should be the primary environment problems in a Large amount of freshwater fish culture in Shaanxi Province.
