title: Comparative assessment of the quantitative and qualitative composition of zooperiphyton on the surface of duckweed (&lt;i&gt;Lemna minor&lt;/i&gt;) grown in a recirculating water supply system
abstract: Relevance. The quantitative and qualitative composition of organisms settling on floating macrophytes depends on the presence in the water of nutrients necessary for their life, such as fish waste products, food residues and excrement. Methods. The roots and leaves of duckweed ( Lemna minor ) act as a substrate for the attachment and development of aquatic organisms. And they, in turn, consume organic substances as food sources, thereby reducing the amount of pollutants in the water. In this reg
