The Czech Limnogical Society is an association of limnological researchers on all levels – scientists, teachers, students – in both theoretical and applied fields. Limnology is the science that studies all aspects of bodies of fresh water: biological, chemical, and physical, both surface waters and groundwaters. The Society is a member of the Council of Scientific Societies of the Czech Republic and the European Federation for Freshwater Sciences (EFFS).
The Czech Limnological Society is the successor to the Czechoslovak Limnological Society, which was established in 1966. It continued the activities of the “Hydro-biological Committee” associated with the Czechoslovak Academy of Science, which from 1951 sought to co-ordinate and develop cooperation between researchers and institutions concerned with both fundamental and applied research in the field of water and water management. From the prevailing trends of creating taxonomies of fauna and fish in the 1960s, the development of the field of hydro-biology proceeded in the direction of the quantification of organisms and determination of their activities and became even more focused on solving the dynamics of processes in water (interaction between non-biotic factors and biotic processes, questions relating to the production of water biocenoses, etc). This trend and the relationship with the international organisation of limnologists necessarily also led to the expansion of the scope of the original hydro-biological orientation and a limnology society was also established in Czechoslovakia in 1966.
The above development was also reflected in the membership, with the register of people active in hydro-biology and “related branches” including 169 names, while the first register of members of the Czechoslovak Limnological Society associated with the Czechoslovak Academy of Science included 230 names. Only 99 people were included in both registers. The number of members in the 1970s and 1980s was around 250. The split of Czechoslovakia in 1993 also resulted in the Czechoslovak Limnological Society splitting into the Czech Limnological Society and the Slovak Limnological Society. However, close cooperation continues and regular conferences organised at three-year intervals are also common to both societies, with only organisational matters ensuing from the constitution being solved in separate meetings.
The organisation of regular conferences is one of the proven tools to enhance the exchange of the latest information on the problems being addressed by the respective parties and to facilitate discussions about pressing issues in the field and trends in research and the broader application of their outcomes. The tradition of these conferences dates back to 1951, when the first “hydro-biological conference” was held. Starting with the seventh conference, which took place in Bystřička na Moravě in 1997, regular three-year meetings have continued as “limnological conferences”. Issued on a quarterly basis, the “Limnologické noviny” (formerly “Zprávy CSLS”) journal is a source of information for the members of the Czech Limnological Society.
