| Abstract: | The paper studied the regulation of protein fractionator to water quality of Litopenaeus vannamei by measuring physical and chemical factors in culture period of ponds. The results showed that the pH value of water maintained at between 8.0-8.3 after using the protein fractionator. The highest concentration of ammonia （NH4＋-N） ,nitrite nitrogen （NO2-N） and chemical oxygen demand （COD） in culture period were 0.917mg/L, 0.324 mg/L and 14.27 mg/L, respectively. The content of the dissolved oxygen （DO） maintained at between 3.775-5.500 mg/L. After using the proteinfractionator was in effect at removing of micro-suspended solids and COD, and also could take off some ammonia （Nt-L＋-N） and nitrite nitrogen （NO2-N）. |
