WebUse of biomanipulation to force a switch from turbid, phytoplankton-dominated lakes to clear-water, macrophyte-dominated systems is a well documented restoration strategy for shallow freshwater lakes (see Moss et al., 1996; Scheffer, 1998). Despite the large number of cases documenting the switch between WebBiomanipulation resulted in a significant decrease in phytoplankton biomass in general and biomass of bloom-forming cyanobacteria in particular that were associated with a significant increase in large Cladocera density and size. In six out of nine ponds biomanipulation resulted in the restoration of submerged vegetation.
