Eutrophication resulting from high nutrient loading has been the paramount environmentalproblem for lakes world-wide for the past four decades. Efforts are being madein many parts of the world to reduce external nutrient loading via improved wastewatertreatment or diversion of nutrient-rich inflows. However, even after a reduction of theexternal phosphorus loading, the effects obtained may be unsatisfactory. This mayreflect an insufficient reduction in the external nutrient loading to effectively limit phytoplanktongrowth. However, the lack of success may also be due to chemical or biologicalwithin-lake inertia preventing or delaying improvements. To overcome theresistance and thereby reinforce recovery, a number of physico-chemical and biologicalrestoration methods have been developed.In this chapter, we describe recent developments of biological restoration methodsrelated to eutrophication, their short-term and long-term effects, and discuss thepossibility of using combined physico-chemical and biological methods to improvethe long-term stability of restoration and to reduce restoration costs. As comprehensivereviews of the effect of fish manipulation in cold temperate lakes are numerous, forthese waterbodies, we highlight recent results, including effects on biodiversity andmetabolism, and present new approaches of biomanipulation. Our particular focus is,however, directed at biomanipulation in warm lakes and on combined treatmentswhich are far less well described in the literature.
