| Abstract | A field mesocosm experiment was conducted at the Three Gorges Reservoir to investigate the utility of black wattle extract in controlling blue algal blooms. The mesocosm experiment was divided into two parts: (1) a short-term test to evaluate how black wattle extract inhibits algal blooms in an emergency and (2) a long-term test to evaluate how black wattle extract maintains water quality and prevents algal blooms over a 1-year period. In the short-term test, the results showed that 3 to 4 mg L-1 black wattle extract could reduce algal biomass in 1 week, whereas serious algal blooms occurred in the untreated control mesocosm. More importantly, the long-term test suggested that black wattle extract played a significant role in plankton structure optimization at lower concentrations of 1 to 2 mg L-1. In this test, phytoplankton diversity increased, with the dominant species shifting from cyanobacteria to diatoms and other algae. Meanwhile, as water quality improved through the presence of plant extract treatment, the numbers of smaller zooplankton decreased and larger species increased. Therefore, this investigation founded a novel nature plant agent that not only has good effects on algal bloom control, but also restores the aquatic ecosystem. Water Environ.
