| 摘 要： | 调查和监测了60口优质鱼类养殖池塘水质理化因子和生物因子共31项，结果发现，多发病的鱼塘亚硝酸盐含量比少发病的鱼塘高，其含量均值分别为0.176,0.095mg/L,以彭泽鲫（Carassius auratus)为试验材料，测定亚硝酸盐对血红蛋白的毒性影响，结果表明，鲫血液中的高铁血红蛋白（MHb) 随NO2－N浓度的增加呈指数递增关系，1.8mg/L和0.8mg/LNO2-N分别为48h 和 96h毒性影响的临界值，养殖水体增加足量溶氧，适量的氧化剂，氯离子和硝化细菌，可降低亚硝酸盐的含量。

| Abstract: | We measured 31 physicochemical and biological parameters in 60 qualified cultured fishes ponds. The result shows that the frequently ill-caught ponds have higher nitrite than the occasionally ill-caught ponds. Their quantity of nitrite were 0.176 mg/L. and 0.095 mg/L, respectively. We have also test the effect of toxicity of nitrite on Hb in \%Carassius auratus (Var. pengze)\% blood. It turns out that the toxicity of nitrite makes the blood index of MHb in this fish increase with increasing in NO\-2-N density. It was found that critical values of toxic action after 48 hours and 96 hours were 1.8 mg/L and 0.8 mg/L, respectively. If we add adequate dissolved oxygen, just the right amount oxidant, Cl\+- or Nitrobacteria in cultured water,then it will lower the quantity of nitrite. |
