CliSAP successfully finished in 2018. Climate research continues in the Cluster of Excellence "CLICCS".

Marine Ecosystems: Effects of Climate Change


Climate change and overfishing are affecting ecosystems all over the world. That was the result of a workshop at the Institute for Hydrobiology and Fisheries Science last week. The basis for the deliberations was formed by various long time series of data on 20 different ecosystems, for example in the North Sea, the Baltic Sea, Canada, the USA, the Black Sea and the Mediterranean Sea. Possible causes for the changes are large-scale climate change as well as local human impacts such as overfishing and over-fertilization of surface waters.

Around 30 scientists from 14 countries discussed possible early warning signs: “If we learn to better understand the mechanisms which cause regime shifts, then it may be possible to identify drastic ecosystem change earlier. “This would make a better ecosystem management possible” reports Prof. Christian Möllmann. The fisheries biologist investigates the influence of climate on commercially utilized fish stocks and works together closely with colleagues from partner institutes in Norway, Sweden and Denmark. One of the main issues, for example, is an anticipatory fisheries management for the Baltic Sea, where the cod stocks have been negatively affected by climate change.

The successful cooperation will be expanded next year and extended to the Pacific region. For this, in May of 2011, in the framework of the International Council for the Exploration of the Sea, a further workshop will be held at the KlimaCampus in cooperation with the Leibniz Institute for Baltic Sea Research in Warnemünde.
