Herring research since the 1980s

Baltic herring research

Research on the reproductive biology of Baltic herring was started at the Archipelago Research Institute and the Department of Biology in the beginning of the 1980s. Since then, the herring research has continued in the form of several scientific and monitoring projects that have been carried out in the Archipelago Sea area, and especially at the vicinity of the city of Turku, where one of the major herring reproductive areas is situated. The data are based on field sampling of the spawning fish, and direct monitoring of the spawning beds by scuba diving. During this three-decade biological survey, the environmental conditions of the spawning area have changed considerably, e.g. due to eutrophication and decreasing salinity of the Baltic Sea.

These pages present some results of this project, and also provide general information on Baltic herring, which, despite of its small body size, is an important component of both the Baltic ecosystem as well as the Baltic fisheries.
