In the Barents Sea, recruitment of North-East Arctic cod is affected by sea temperature, being higher in warm years. Cod dynamics are furthermore influenced by time-lagged competition for capelin with herring, and the intensity of size-selected harvesting. The system is not stable in three ways: (1) the effect of temperature...
In this paper, a three-country dynamic bio-economic model is presented and used to simulate catch levels, stock size and profit potential of alternative management strategies for the Norwegian spring-spawning herring fishery. Management of the herring fishery is complicated by the migratory behaviour of the species moving between coastal state zones...
This paper analyses the management of the Atlantic salmon stocks in the Baltic Sea through a coalition game in partition function form. The signs of economic and biological overexploitation of these salmon stocks over the last two decades indicate that cooperation among the harvesting countries, under the European Union's Common...
