Hydrobiology

Special attention is paid to biotic interactions in plankton assemblage including the microbial loop, the mechanism of influencing algal blooms, phosphorus load, and lake turnover.

[1][2] Long-term studies are carried out on changes in the ionic composition of the water of rivers,[3] lakes and reservoirs in connection with acid rain and fertilization.

Much of the early work of hydrobiologists concentrated on the biological processes utilized in sewage treatment and water purification especially slow sand filters.

In the event of pollution, they propose solutions to improve the biological quality of water within the framework of the regulations in force.

The hydrobiologist works on behalf of large public institutions of a scientific and technological nature (CNRS, INRA, IRD, CIRAD, IRSTEA ...), public institutions (Water Agencies, Regional Directorates environment, Higher Council of Fisheries, CEMAGREF ...), companies (EDF, Veolia environment, Suez environment, Saur, ...), local authorities, research departments, and associations (Federations of fishing, Permanent Centers for Environmental Initiatives ...).
