Professor Elek Woynárovich arrived in 1 September 1961. at the then called Kossuth Lajos University of Arts and Sciences, Faculty of Natural Sciences as a head of Department of Zoology. He suggested first in 1969 to start training Hydrobiologists in the University. Following this begun the establishment of the scientific and teacher base of this new area of science. Since 1962 the subject Hydrobiology could be attended as an elective course.
The Hydrobiologists training started in 1966 at the Kossuth Lajos University of Arts and Sciences, Faculty of Natural Sciences and it lasted for ten years. For three years it worked as a special training besides two teacher lines (biology and chemistry). The first class graduated in 1967. Amongst them were György Dévai (University of Debrecen, Faculty of Science and Technology, Professor emeritus), Péter Bíró (Balaton Limnological Research Institute, director and academic), Keve Tihamér Kiss (scientific advisor, The Institute of Botany of the Hungarian Academy of Sciences (HAS, HDRC), DSc) and József Hamar (Tisza-Club, president). After leaving of Elek Woynárovich in 1968 Jenő Szabó and György Dévai governed and organized the instruction. Lajos Felföldy titular professor, Péter Pásztó and Pál Gulyás titular lecturers were also joined to educate the Hidrobiologists. From 1969 it became possible to replace one of the teacher lines with the Hydrobiology line. The naming of the diploma was: "Certified biology line assistant-master and Hydrobiologist". In this way the last class graduated in 1977. In 1975 the starting of the independent Biologist line broke with this way, when the interested students could hear the lecture in the frame of the Biologist training. The main educational frames were provided by first the Department of Zoology, Department of Zoology and Anthropology, and then by the Department of Ecology founded in 1980. The Department of Applied Ecology was separated from the united Department of Ecology in 1998. Within the Department of Ecology started working the Hydrobiological Section which was the predecessor of the Department of Hydrobiology. The Hydrobiological Section played a significant role to organize the "Watery ecology" doctoral (PhD) program (1993) and the "Environmental Sciences" doctoral school's "Hydrobiology" program (2002).
The independent Department of Hydrobiology was formed in 2003 in the University of Debrecen. The Department makes its own business to study the hydrobiological sciences in the level of scientific research, and to transfer the hydrobiological knowledge in every level of education (doctoral training, gradual training, post gradual training and educational).
The greatest success in the history of the Department of Hydrobiology was that the Hungarian Accreditation Committee (HAC) permitted in the number 2007/10/XII/2/2. declaration the foundation of the Hydrobiologist Master of Science course in our Country which was requested by a Consortium coordinated by the Department of Hydrobiology and lead by the University of Debrecen. The HAC also supported, in a session organized in 25 January 2008 in the number 2008/1/XI/1/6. declaration, the application of the University of Debrecen to start the Hydrobiologist Master of Science Training.
According to this in the September of 2009 in the University of Debrecen - in the management of the Faculty of Science and Technology - the Hydrobiologist Master of Science course (MSc) was started.
