A Coalition Game of the Baltic Sea Cod Fishery

Kronbak, Lone Grønbæk - 2004

The paper sets up a discrete-time, deterministic, coalition game model among the major agents exploiting the cod stock in Baltic Sea. The characteristic func-tion is constructed and the Shapley value and the nucleolus are used as one-point solution concepts. The paper identifies the problem with...

An Optimal Corrective Tax for Thai Shrimp Farming

Pongthanapanich, Tipparat - 2005

"If Thai shrimp farming were taxed, how much should it be?" is the key re-search question of this paper. The dynamic-constraint optimization model in-corporating accumulated nutrient load from farm discharges is applied in the analysis. The model implies some tax has to be imposed on stock...

On species preservation and non-cooperative exploiters

Grønbæk Kronbak, Lone; Lindroos, Marko - 2008

Game-theoretic fisheries models typically consider cases where some players harvest a single common fish stock. It is …, however, the case that these types of models do not capture many real world mixed fisheries, where species are biological … fisheries. This paper is targeting biodiversity preservation by setting up a two species model with the aim of ensuring both …

Cost-benefit analysis of the Greenland offshore shrimp fishery

Vestergaard, Niels; Stoyanova, Kristiana A.; Wagner, Claas - 2010

This paper examines the social economic value of the Greenland off-shore shrimp fishery. The contribution of the fishery to the economy is examined using a cost-benefit analysis where the objective of the report is to examine the current state of the fishery rather than possible changes, which...

A size-based ecosystem model

Ravn-Jonsen, Lars J. - 2009

Ecosystem Management requires models that can link the ecosystem level to the operation level. This link can be created by an ecosystem production model. Because the function of the individual fish in the marine ecosystem, seen in trophic context, is closely related to its size, the model groups...
