The rise and fall of the Great Fish Pact under endogenous risk of stock collapse
Walker, Adam N.; Weikard, Hans-Peter; Richter, Andries - 2015
Risk of stock collapse is a genuine motivation for cooperative fisheries management. We analyse the effect of an …

Optimal fishery with coastal catch
Uecker, Hannes; Bayındır-Upmann, Thorsten - 2016
In many spatial resource models it is assumed that the agent is able to determine the harvesting activity over the complete spatial domain. However, agents frequently have only access to a resource at particular locations at which the moving biomass, such as fish or game, may be caught or...

Harvesting a Remote Renewable Resource
Upmann, Thorsten - 2018
In standard models of spatial harvesting, the resource is distributed over the complete domain and the agent is able to control the harvesting activity everywhere all the time. In some cases though, it is more realistic to assume that the resource is located at a single point in space and that...

A Stochastic Differential Fishery Game for a Two Species Fish Population with Ecological Interaction
Wang, Wen-Kai; Ewald, Christian-Oliver - 2015
We combine and extend two existing lines of research in game theoretic studies of fisheries. The first line of research … is the inclusion of the aspect of predation and the consideration of multi-species fisheries within classical game … theoretic models of fisheries and goes back to Quirk and Smith (1977), Anderson (1975) and most recently Sumaila (1996). The …

Does the optimal size of a fish stock increase with environmental uncertainties?
Kapaun, Ute; Quaas, Martin F. - 2012
'convex-cost effect' and the 'gambling effect'. We apply the analysis to the Baltic cod and the North Sea herring fisheries …

Robust control of a spatially distributed commercial fishery
Brock, William A.; Xepapadeas, Anastasios; … - 2013
We consider a robust control model for a spatially distributed commercial fishery under uncertainty, and in particular a tracking problem, i.e. the problem of robust stabilization of a chosen deterministic benchmark state in the presence of model uncertainty. The problem is expressed in the form...

Effects of Rotation Scheme on Fishing Behaviour with Price Discrimination and Limited Durability : Theory and Evidence
Seki, Erika - 2008
This paper examines how rotation arrangement between two groups of Japanese fishers with different institutional arrangements affects fishing behaviour and economic outcomes in a particular economic environment characterised by price discrimination and product durability. In one group, fishers...

Optimal Fishing Mortalities with Age-Structured Bioeconomic Model - A Case of NEA Mackerel
Ni, Yuanming - 2016
The effects of random environmental impacts on optimal exploitation of a fish population are investigated using both optimization and simulation, based on a discrete-time age-structured bioeconomic model. The optimization problem is solved as a non-linear programming problem in GAMS. First, a...
