Abstract:

To study the influence of the floating bed culture of Jussiaea stipulacea (0, 5% planting area) on the pollutants in the culture pond of red tilapia (Oreochromis mossambicus× O. niloticus), the water quality indexes, such as CODMn, Chl.a, TN, NH3-N, NO2 --N, NO3--N, TP and PO43--P, were determined. The results showed that compared with the control group, J. stipulacea could significantly reduce the contents of Chla, NH3-N, NO2 --N, as well as the contents of CODMn, TP, TN and NO3 --N in the culture ponds of red tilapia. The average removal rate of NO3--N and NO2--N was more than 50%, but the removal effect on phosphorus was unsatisfactory.
