IIFET 2012 Tanzania Proceedings 1 OPTIMAL MANAGEMENT OF CONFLICTING SPECIES: GREY SEAL (HALICHOERUS GRYPUS) AND ATLANTIC SALMON (SALMO SALAR) IN THE NORTHERN BALTIC SEA
In the Baltic Sea, the successful conservation of grey seals has increased seal-induced damages to the Atlantic salmon fishery. The paper addresses the conflict between the conservation of the formerly endangered species and professional fishermen whose livelihood is also regulated by fisheries mana...
