Hydrobiology is the science of life and life processes in water. Much of modern hydrobiology can be viewed as a sub-discipline of ecology but the sphere of hydrobiology includes taxonomy, economic biology, industrial biology, morphology, physiology etc. The one distinguishing aspect is that all relate to aquatic organisms. Much work is closely related to limnology and can be divided into lotic system ecology (flowing waters) and lentic system ecology (still waters).
One of the significant areas of current research is eutrophication. Special attention is paid to biotic interactions in plankton assemblage including the microbial loop, the mechanism of influencing water blooms, phosphorus load and lake turnover. Another subject of research is the acidification of mountain lakes. Long-term studies are carried out on changes in the ionic composition of the water of rivers, lakes and reservoirs in connection with acid rain and fertilisation. One goal of current research is elucidation of the basic environmental functions of the ecosystem in reservoirs, which are important for water quality management and water supply.
Much of the early work of hydrobiologists concentrated on the biological processes utilised in sewage treatment and water purification especially slow sand filters. Other historically important work sought to provide biotic indices for classifying waters according to the biotic communities that they supported. This work continues to this day in Europe in the development of classification tools for assessing water bodies for the EU water framework directive.
The hydrobiologist technician conducts field analysis. It identifies plants and living species, locates them, counts them. It identifies pollutions and nuisances that can affect the aquatic fauna and flora. He takes the samples and writes a report of his observations.
The hydrobiologist engineer intervenes more in the process of the study. It defines the intervention protocols, the samples to be taken. He plans and programs the study campaigns and then summarizes his results. In the event of pollution, it proposes solutions to improve the biological quality of water within the framework of the regulations in force and the available means. In the case of complex programs, the hydrobiologist can work in a multidisciplinary team with botanists, zoologists
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, associations (Federations of fishing, Permanent Centers for Environmental Initiatives ...).
Training and studiesEdit
The biologist technician usually has a training level bac +2 or bac +3:
- DUT biological engineering options biological and biochemical analyzes (ABB), environmental engineering,
