Ecological Characteristic of a Highly Eutrophic Pond: The Role of Green Algae in Eutrophication

Abstract

Patriarch’s Pond is a small water body located within the boundaries of Moscow, where regular and mass blooms of green algae are observed. Various fish species exhibit intermittent spawning throughout the summer, and young fish of different sizes are consistently present in the pond, primarily consuming large zooplankton individuals. This predation results in a shift in the size structure of the zooplankton population toward smaller species. A total of twenty-three zooplankton species have been recorded in the pond, with rotifers being the most abundant. Phytoplankton analysis revealed the presence of 106 species of algae and cyanobacteria, with green algae comprising 67 species.
