According to the water quality monitoring results, drainagequantity and pattern, pollution intensity of the main water qualityindex in aquacultural ponds was estimated. The pollution intensityin the present study was also compared with general aquaculturepond in Shanghai. It was found that the intensity of CODCr, TP andTN in this research was 3201 kg/ha, 25.7 kg/ha and 128.6 kg/ha,respectively, all of which were higher than general aquaculturepond in Shanghai (Xu, 2003).
