The results showed that: the influence of the aquaculture process on aquaculture water determined by type of aquaculture; the influence of aquaculture process on the water temperature, salinity and pH value were not wide.the descent of pH value was related to feed coefficients ; the dissolve oxygen of water in outfall was lower than the water in infall,but the concentration still maintained at the saturation level, is mainly affected by density of aquaculture ,rate of feed and artificial measures of increasing oxygen ;the major form of inorganic nitrogen was nitrate-N;the concentration of inorganic nitrogen and the organic matter tended to increase ,but the ammonium to decline ,this was relation with density of aquaculture ,rate of feed and variation of the different inorganic nitrogen form ; concentration of phosphate-P was low in outfall of pond , related with phosphate-P precipitating, as flowing water speed slowly in outfall;This phenomenon that the total number of bacteria and coli form group of water in outfall was lower than the water in infall , this caused by measures of sterilization and disinfection .

结果表明：养殖过程对水体影响与养殖类型有关。养殖过程对水体的水温、盐度和pH影响不大； pH下降与饲料系数高有关；溶解氧含量排水口比进水口低，但仍维持在饱和状态，与养殖密度、投饵率和人工增氧有关。硝酸氮是无机氮的主要存在形式，无机氮和有机物含量有升高趋势，氨氮有下降的趋势，与养殖密度，投饵率和各种无机氮之间的相互转换有关。活性磷酸盐含量在排水口含量下降，与排水口流水速度慢，磷酸盐沉淀有关。生物指标细菌总数和大肠杆菌总数在排水口比进水口低现象普遍存在，这与养殖场杀菌消毒等措施有关。

Based on the results of water quality (physical and chemical factors: water temperature, salinity, pH, DO, DIN, PO4-P, COD, and biomarker-indicated: total bacteria and Coliforms) determining from the 4 pools and infall, outfall of the Xishan Island aquaculture pond, the variation characteristics of water quality in infall, outfall of pond and its reasons were analysised and discussed.

结果表明：养殖场和进、排口水体温度、盐度变化不明显，pH下降与养殖周期有关；营养盐含量增加，在不同养殖种类、养殖周期和养殖饲料系数变化不同；受消毒杀菌等措施影响下细菌总数与大肠杆菌总数明显减小，而养殖周期长的池塘，细菌总数仍增加，大肠杆菌总数减少幅度变小。
