Ecological mechanism behind dredging revealed to mitigate lake cyanobacterial blooms

Cyanobacterial blooms caused by water eutrophication have become a global environmental problem. Dredging, alternatively known as removal of sediment, has been reported as an effective approach for mitigating cyanobacterial blooms, and plays important roles in enhancing water quality of urban lakes. However, the research on the ecological mechanisms behind dredging is not deep enough.
