In order to identify the possible factors currently limiting the re-establishment of salmon populations in potential salmon rivers, we compare a wild salmon river with potential salmon rivers in terms of the biological characteristics of the salmon population, the fishing pressure on the population and the river s socio-economic and biological environment. The differences in biological and socio-economical circumstances between rivers can be examined through separate biological, economical and socio-economic studies. The results from the different disciplines can later be linked together within one single probabilistic or Bayesian network model. The probabilistic network has the advantage that the different conditional relationships can be obtained through different methodologies. In the case of Baltic salmon, the ...
