This paper investigates the application of cellular automata (CA) models in bioeconomic studies involving varying biological growth and area distribution. A simple 2D continuous cellular automata (CCA) model is presented and incorporated in a fish harvest model based on standard assumptions of economic rational behaviour by individual decision makers. The...
A number of simulations have been carried out to study different management scenarios in the Barents Sea cod fisheries when implementing physical and biological effects of global warming. A regional representation of the IPCC SPRES B2 scenario (world region OECD90) has been obtained through the REMO5.1 model. Water temperatures and...
Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish
population-dynamics and production, coupled with an aquaculture production model, to investigate
effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying
capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production....

This is a study on economic implications of the 3 year harvest control rule (HCR) for the Northeast Arctic
cod stock, decided in November 2002 by the Joint Norwegian-Russian Fisheries Commission. Outcomes
of this rule are compared to those of five other rules, including the previous one based on a...

We estimated the economic rent obtained currently (that is, in 2002) in the Namibian hake fishery and the rent that might potentially be obtainable if the fishery were managed optimally in the sense of economics. We first reviewed previous economic and biological studies. We then used the theory and model...
