Regional economic impacts of fish resources utilization from the Barents Sea: Trade-offs between economic rent, employment and income

摘要

A multi-objective programming model has been developed to investigate the trade-offs among regional employment, regional income, and economic rent of the North Norwegian cod fisheries in the Barents Sea, where all vessels are regulated by an individual quota system. Fishery managers are confronted with the problem on how best to allocate the total allowable catch (TAC) among four vessel groups. It is apparent that depending on how fishery managers view the importance of each objective, the desirable allocation of TAC will differ. Therefore, the trade-offs information can be very useful to fishery managers indicating the relative "expensiveness" of trading one objective with another. Decision maps are generated depicting how the trade-offs between two objectives are affected by the third objective. Compromise solutions taking into account all three objectives will allocate the TAC to satisfy the maximum capacity of both the factory trawlers and the small-scale vessels with the remaining TAC distributed to the coastal fleet and fresh fish trawlers.
