| 摘 要： | 对凡纳滨对虾高位养殖池水质环境状况进行了研究。结果表明,养殖期间虾池水体透明度前期较高,中后期较低;虾池pH变化在7.89~9.02之间,变化幅度较小。虾池水体悬浮物数量和CODMn随养殖时间延长而持续升高,变化范围分别为18.5~162.3 mg/L和3.52~14.58 mg/L。虾池水体中营养盐各月份波动较大,无机氮的数量变化在0.206~1.621 mg/L之间,含量逐渐升高,磷酸盐数量变化在0.009~0.067 mg/L之间,含量逐渐下降。水环境中N、P比较高,平均为62.7。养殖水体中后期处于严重富营养化状态。 |

| Abstract: | This paper dealt with the physiochemical traits of the water in the higher-altitude Litopenaeus vannamei culture ponds.Results showed that the water transparence was better in the early period of culture than in the middle and later periods;pH value altered in the range of 7.89 to 9.02;the amount of suspended matters in the ponds fluctuated from18.5 to 162.3 mg/L;COD of the pond water altered in the range of the 3.52to 14.58 mg/L,averaging 9.65 mg/L;COD and the amount of suspended matters increased steadily with the cultural time.The amount of inorganic nitrogen altered in the range of 0.206-1.621 mg/L,averaging 0.796 mg/L;the amount of the phosphate altered in the range of the 0.009-0.067 mg/L,averaging 0.028 mg/L.The amount of nitrogen increased gradually while the amount of phosphate decreased gradually and resulted in a considerable high ratio of N/P(range 22.1-189.3,mean 62.7).Taken all aspects into accounted,the water quality was in the state of supereutrophication. |
