Periphyton

 

freshwater organisms that live attached to the underwater parts of riverboats, beacons, piers, and other man-made structures. The term was proposed by the Soviet hydrobiologist A. L. Bening in 1924. It was subsequently used to designate the overgrowth of marine hydroengineering structures with organisms. At present, the term is almost never used and has been replaced by the term “fouling.”

Diatoms belonging to the family naviculaceae have adapted to streams with high flow rates or systems with a high incidence of sediment entrainment or that have been influenced by significant runoffs, which also usually consist of certain substances with a high energetic value, therefore constituting an important offer for macroinvertebrates and fish that feed on periphytic algae (25).
The primary producers collected included leaves from overhanging riparian terrestrial trees (Fagus sp.), periphytic algae, and the dominant aquatic macrophytes (primarily watermilfoil Myriophyllum spicatum) that were present in both habitats.
