Biomanipulation an effective way of reducing algal blooms
For the first time, a systematic review has been undertaken of the use of biomanipulation to restore eutrophic lakes. Removing roach, bream and similar fish to increase populations of zooplankton, which in turn feed on phytoplankton, has been shown to be a successful method of improving water quality.The extensive review has been conducted by the Mistra Council for Evidence-Based Environmental Management (EviEM). ‘By looking at a very large number of lakes, we’ve been able to show that this method is actually effective in improving water quality. We can also see under what conditions it
