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...
The theoretical economic performance of the year 2000 Norwegian fishing fleet in the Barents Sea cod fisheries are studied under different stock biomass levels and age compositions by applying the EconMult fleet model. Quarterly stock conditions during the period 1946-2004 have been investigated as this represent stock conditions which may...
The objective of this study is to investigate the sustainability properties of the stock of the shrimp trawl
fishery in the Tonkin Gulf, Vietnam. Surplus production models of Verhulst-Schaefer and Gompertz-Fox
are applied to the shrimp trawl fishery, which is a typical tropical fishery with the characteristic properties
of small...
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...
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....
