Abstract: The Baltic Sea has been severely affected by pollution and resource overexploitation during the last centuries. The grey seal (Halichoerus grypus) is a good example of how a species can be affected by such changes. In the early 1900s grey seals were common, but hunting and environmental contaminants caused a rapid decline to the verge of extinction in the 1970s. Since the 1980s the population is increasing. This has intensified the conflicts between seals and fisheries, and resource competition ... more
