Evaluation of the Filtration Activity of the Dreissena Polymorpha Southern Invasive Species for the Ivankovo Reservoir

Abstract—Bivalve mollusks are an important component of the ecosystems of many natural and artificial reservoirs. However, the ecological role of some of them is very ambiguous, especially if we talk about invasive species that have spread widely beyond their natural habitats over the past 100 years. The present study aims to obtain quantitative estimates of the distribution of a southern invasive species, the zebra mussel bivalve mollusk, over the water area of the Ivankovo reservoir and to assess the contribution of its filtration capacity to water self-purification.
