Limnologica publishes original contributions, news, and reviews dealing with any aspects of ecology and hydrobiology of inland waters and adjacent biotopes. Also discussions and essays that develop limnological-ecological theory are published (including all qualitative and quantitative aspects of planktonic, periphytic, benthonic, neustonic, and nektonic organisms, nutrient and energy flow, bioindication, biomonitoring, water-internal control mechanisms, ecological modeling and simulation, biological-ecotechnological water quality and fisheries management, protection of water and restoration).

Publishing articles on theoretical and basic questions, Limnologica is dedicated to the protection and restoration of inland waters and therefore also covers practical themes.
