Biomanipulation, the reduction of planktivorous fish to enhance filter‐feeding zooplankton, has been used to rehabilitate eutrophied lakes. However, efficacy and long‐term success were dependent on nutrient load, lake morphometry and biomanipulation measures. The ongoing focus on sustainable use of aquatic resources offers the chance to perform lake rehabilitation using a combined strategy of nutrient load reduction and traditional inland fisheries management techniques. Particularly in Central and Western Europe where piscivorous fish are the target species of most commercial and recreational fisheries, an enhancement of the piscivores by stocking and harvest regulations may act successfully in the co‐management of ecosystem and fisheries. Guidelines are presented on how biomanipulation can be used as in lake rehabilitation by considering the objectives and constraints of traditional fisheries management. Alternatives in the decision tree are elucidated by examples from biomanipulations and lake management programmes in the temperate zone of Europe and North America. It is suggested that biomanipulation may support many lake rehabilitation programmes where fisheries’ stakeholders are the principal user groups.
