Analysis of phytoplankton-zooplankton relationships in an oligotrophic lake under natural and manipuy nutrient-limited. The effects of biomanipulation on zooplankton-phytoplankton relationships were assessed by monitoring both individual species and whole-assemblage responses. Two sizes of enclosures were used (15 and 350 litres) and two treatments were assayed: 1) removal of zooplankton by 45 .m

Limnological parameters were regularly monitored in all the three water bodies over three months or longer. The objective of the experiments was to induce a clear-water period in turbid eutrophic waters by direct manipulation of the zooplankton community. Introduction of four mil

To assess the potential strength of grazing in each lake, we evaluated algal responses to a 16-fold range of zooplankton biomass. To better compare algal

Why do cladocerans fail to control algal blooms?g clear water phase in lakes) or months (low-stocked fish-ponds). In the absence of planktivorous fish, large-bodied cladocerans effectively control the abundance of algae of a broad size spectrum. Laboratory experiments show that, although difficult to handle and of poor nutritional value, filament

Structural and grazing responses of zooplankton community to biomanipulation of some Dutch water bodhallow) and mesotrophic (deep) lakes in The Netherlands. The biomanipulated lakes had lesser number of species and their abundance, both of rotifers and crustaceans, and had much larger mean animal size (3–11 .g C ind..) than in the unmanipulated eutrophic lakes (0.65 .g C ind..).
