Coregonid fish research

Welcome to our website! We update and publish research information related to coregonids, their populations and population monitoring methods on this website, e.g. larval density time series of research lakes. The research results are partly based on the Cornet-project. We also study the effects of sulphate on different freshwater and brackish water species. The research group consists of professor Juha Karjalainen, docent Timo J. Marjomäki, doctoral researchers Tuula Väänänen, Xiaoxuan Hu and Mikko Mäkinen, master's students Venla Borg and Pinja Peltonen and laboratory technician Jonna Kuha and a number of seasonal workers.

Research group description

At the Department of Biological and Environmental Sciences at the Ģֱ, we work for sustainable fish stocks, and conduct research on e.g. the effects of sulphate on the reproduction of coregonids, the state of coregnid fish populations in Finland, and develop monitoring methods. For example, the larval catching method has been used to collect data on the densities of newly hatched whitefish and vendace larvae in Konnevesi, Puula and Tehinselkä in Päijänne for over 20 years. We also study the effects of sulphate on different aquatic organisms to contribute to the development of sulphate environment quality standards and the understanding of sulphate toxicity on different species.
