Control of Cyanobacterial Blooms via Synergistic Effects of Pulmonates and Submerged Plants
Control of cyanobacterial blooms remains a major challenge in the restoration and management of eutrophic waters. In this study, a synergistic approach of snails and submerged plants was used for controlling cyanobacterial blooms in a series of simulated experiments. Individual and/or combined effects of a pulmonate (Radix swinhoei) and a submerged plant (Potamogeton lucens) on cyanobacterial blooms were determined. The effect of R. swinhoei on the cyanobacterial decrements was not obvious but inversely increased nutrient concentration. However, aquatic plants had certain effects reflected by decreased concentrations in chlorophyll a, total nitrogen, total phosphorus and the potassium permanganate index to 31.5, 17.9, 48.6 and 21.1%, respectively, after a ten days experimental period. Furthermore, when snails and plants were combined, these ratios disproportionately reached 76.2, 51.4, 55.6 and 31.6%, respectively. Results confirmed that use of a combination of snails and submerged plants to eliminate cyanobacterial bloom in eutrophic waters may be a helpful tool in eutrophication control.
