| 摘 要： | 利用外荡养殖三角帆蚌,对养鱼水体进行了改善水质的试验。通过测定分析水体的pH、化学耗氧量、总氮、总磷等水质指标,评价水体水质的变化,探讨了三角帆蚌对养殖水体主要水质因子的可能影响。在高温季节,养鱼水体混养三角帆蚌的生物调控系统水质较好,经三角帆蚌的净化可使养殖水体COD值、总氮和总磷分别下降44.74%、70.81%和70.45%。而在低温季节,三角帆蚌对水体的净化作用较差。研究结果表明:鱼蚌混养系统可有效地改良水质,可望较好地延缓水体的富营养化,具有较好的应用前景。

| Abstract: | The influences of the polyculture of Hyriopsis cumingii with fish in an open pond on the major parameters of water quality were analyzed.The eutrophication extent of the water body was analyzed according to the water quality indexes,such as pH and amounts of COD_(Cr),TN,TP,etc.The results showed that the quality of the water in experimental systems were good.In the mussel-fishes co-cultivating system,the content of COD_(Cr),TN and TP are reduced by 44.74%,70.81%and 70.45%respectively,by applying the co-culturing system in high temperature seasons.But the effect was not obvious during the seasons with low temperature.The results indicated that application of the fish-mussel co-culturing system are promising for improving the water quality,especially for the controlling of eutrophication. |
