In the Baltic Sea special concerns have been raised about the ecological effects of fishing, not only because fishing affects the target species, but also because the decline of top predators causes changes at several trophic levels, which cause serious disturbance of the whole ecosystem. The severe decline in Baltic Sea top predator species clearly shows that the fishery management of today is not satisfying.
In November 2006 a one day workshop, focusing on the ecological effects of fish and fisheries in the Baltic Sea was arranged. The aim of the workshop were to identify knowledge gaps and needs for development, and propose measures that would help bring back the Baltic Sea to a “healthier state”.
