Baltic herring research
The Baltic herring research project focuses on the reproductive biology of the Baltic herring (Clupea harengus membras) and processes and factors affecting clupeid fish in the Baltic Sea. The research started at the University of Turku in the beginning of the 1980s. Since then, the research on herring has continued in the form of several scientific and monitoring sub-projects, which have been carried out in the northern Baltic Archipelago Sea area and especially in the vicinity of the city of Turku (Finland), where some of the major reproductive areas of herring are situated.
These pages present some results of the project, and also provide general information on the Baltic herring, which despite of its small body size, is an important component of the Baltic ecosystem as well as the Baltic fisheries. Check the research page and contact the research group if you wish to collaborate with us on topics related to our research areas.
