以江苏省连云港市徐圩盐田为研究对象，评价了一个作物周期内对虾养殖对周边水体的影响。水的特征包括3 - 9月10个参数沿进水口和出水口小溪变化的评价。这些参数包括pH、温度、溶解氧、营养物质（铵、亚硝酸盐、硝酸盐和无机磷）、叶绿素a、化学需氧量（COD）和总有机碳（TOC）。出水水体中无机氮（1.5 mg/l）、无机磷（0.024 mg/l）、叶绿素a （0.0025 mg/l）、COD （5.77 mg/l）和TOC （6.57 mg/l）的平均浓度显著高于进水水体（分别为0.33、0.012、0.0018、4.72和3.68 mg/l）。进水和出水水体的pH、温度和DO无显著差异。根据当地法律水质标准，该地区水质污染严重，其中无机氮污染最严重，其次是COD和无机磷。
The effects of shrimp aquaculture on the adjacent water bodies over a crop cycle period were evaluated by studying the water quality of inlet and outlet creeks located within Xuwei Salt Field, Lianyungang City of Jiangsu Province. The characterization of the water consisted of the evaluation of the variation of 10 parameters along the inlet and outlet creeks and during the period of March–September. These parameters were pH, temperature, dissolved oxygen, nutrients (ammonium, nitrite, nitrate and inorganic phosphorus), Chlorophyll a, chemical oxygen demand (COD) and total organic carbon (TOC). Average concentrations of inorganic nitrogen (1.5 mg/l), inorganic phosphorus (0.024 mg/l), Chlorophyll a (0.0025 mg/l), COD (5.77 mg/l) and TOC (6.57 mg/l) at the discharge site in the outlet creek were significantly higher than in the inlet creek (0.33, 0.012, 0.0018, 4.72 and 3.68 mg/l, respectively). There were no significant differences between the inlet and outlet creeks in pH, temperature and DO. With a water quality criteria based on local laws, a significant pollution was observed in the area, with inorganic nitrogen being the most significant pollutant, followed by COD and inorganic phosphorus.
