| Abstract |
| We conduct aquatic ecological research on the potential for rehabilitation of Lake Blankaart as well as on the response of two smaller ponds in the Blankaart nature reserve to earlier biomanipulation measures intended to restore water quality. Research involves monitoring (water quality, phytoplankton, zooplankton, fish community and macrophytic vegetation development) and a field experiment, which involves separating a part of Lake Blankaart (the Keel) through fine-meshed nets and subject this sector to biomanipulation measures. The biomanipulation measures involve the removal of a large part of the plantivorous and benthivorous fish, as well as stocking with piscivorous pike. The sector and the remaining (not manipulated) part of Lake Blankaart will subsequently be compared in a monitoring programme in an effort to establish the response of the lake to rehabilitation measures. |
