As a result of the author’s studies of filter-feeders, he concluded that the filtering activity of populations of filter-feeders in natural habitats might be significantly reduced if the sublethal concentrations of some pollutants reach certain levels. According to the author’s vision, the role of filter-feeders as factors of water purification in ecosystems is so important that their inhibition is a danger for the entire ecosystem. The author emphasized that not only the biodiversity of filter-feeders but also their level of functional (filtration) activity is to be protected. In order to do so, the author suggested establishing a new type of protected areas whose main purpose is to protect functionally active populations of filter-feeders, including bivalves and other organisms. Those protected areas could be named hydrobiological (some variants: biofiltering, or malacological) reserves (some variants: refuges, sanctuaries, etc.). The author formulated a system of five principles of nature conservation requirements  in malacological and hydrobiological reserves. The paper contributed significantly to formation of the ecological basis for environment conservation and especially to conservation of aquatic biodiversity, and also to proper management of aquatic resources towards increasing sustainability and environmental safety, with attention to ecosystem services.
