Abstract：Through the establishment of experimental groups with varying treatment concentrations， systematic monitoring and analysis were conducted on aquatic physicochemical parameters and phytoplankton community dynamics. The findings revealed that biogas slurry demonstrated comparable fertilization eficiency to poultry manure in aquaculture systems， effectively enhancing phytoplankton population density.Notably，higher一concentration treatments exhibited significantly greater enhancement in phytoplankton population density compared to lower- concentration treatments. This evidences biogas slurry's capacity to improve aquatic fertility and stimulate phytoplankton proliferation， thereby creating optimal growth conditions for cultured species. However，biogas residue demonstrated no statistically significant impact on water in fertilization efficacy.
