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.
