The phytoplankton biomass altered from 4.22 mg/L to 22.31 mg/L, averaging 12.29 mg/L. The diversity index of the phytoplankton (H =0.96) was relatively low. The zooplankton identified belongs to 19 species, and its biomass ranged from 3.75mg/L to 7.74mg/L, averaging 5.93mg/L. The diversity index of the zooplankton was relatively low too. In the cultured rice fields, the phytoplankton identified belonging 53 gena, 6 phyla.
