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.
通过研究江苏省连云港市徐圩盐场进出水渠的水质，评估了一个养殖周期内对虾养殖对相邻水体的影响。对水体的表征包括对3月至9月期间沿进出水渠的10个参数的变化进行评估。这些参数包括pH值、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）。出水渠排放点的无机氮（1.5毫克/升）、无机磷（0.024毫克/升）、叶绿素a（0.0025毫克/升）、COD（5.77毫克/升）和TOC（6.57毫克/升）的平均浓度显著高于进水渠（分别为0.33、0.012、0.0018、4.72和3.68毫克/升）。进水渠和出水渠在pH值、温度和溶解氧方面没有显著差异。根据当地法律的水质标准，该地区存在显著污染，无机氮是最主要的污染物，其次是COD和无机磷。
