Development of Aquatic Macrophytes in Shallow Lakes and Ponds,otrophic conditions include, from the lake surface to the lowest part of the littoral, helophytes, nymphaeids, elodeids and isoetids. With increasing pollution and eutrophication of lakes leading to increased turbidity and reduced transparency, first to disappear are the isoetids followed by the elo

Food Web and Trophic Interaction and Development,changes with small changes of zooplankton due to changes in the fish stock, three approaches to the estimation of size of zooplankton were developed: the average length of zooplankton, the percentage of cladocerans >0.71 mm in the total cladoceran biomass, and the length of the average biomass.

Restoration of Eutrophic Lakes by Sediment Treatment, the Alte Donau, a eutrophicated dead-arm of the River Danube in Vienna. Specially-designed equipment has been used to inject nitrate solution directly into the sediment so as to minimise the risk of increasing the nitrogen concentration in the water. Iron salts are usually added to enhance the bind

Restoration of Eutrophic Lakes by Phosphorus Precipitation, with a Case Study on Lake Gross-Glienicosphorus precipitation. Iron or alum compounds are applied to the water to bind and subsequently sediment out phosphorus from the water column. As an example, the successful restoration of Lake Gross-Glienicker (Germany; Berlin/Brandenburg) is described. The injection of iron compounds into the lake

Restoration of Lakes Through Sediment Removal, with Case Studies from Lakes Trummen, Sweden and Vajted by limnologists. This limnological-technological cooperation has aimed at the precision dredging of sediment strata responsible for the internal nutrient loading of lake ecosystems. Suction dredging is mainly restricted to small lakes of high environmental value. Prior to in-lake measures, the e
