In most multi-species fisheries managed through output controls, total allowable catches (TACs) are set primarily on the basis of biological considerations, usually on a species by species basis. An implicit assumption of management is that fishers are able to adjust their product mix in line...

In this paper, a discrete time, multi-gear and age structured bio-economic model is developed for the Northern Atlantic Bluefin Tuna, which is a paradigmatic example of the difficulties faced in managing highly migratory fish stocks. The 1995 U.N. Fish Stocks Agreement provides guidance as to...

This paper considers the policy outcome of a contest between two opposing in-terest groups: the incumbent fishermen and a group of conservationalists. The objective of the fishermen is to maximize profit, and they are (partly) concerned over future profitability as well, while the...

The debate in commercial fishery management has evolved from whether well-defined rights are necessary for sustainability to measuring the impacts of different rights-based system designs. Most assessments are on developed world fisheries. Using a unique collection of datasets, we develop...

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...

In January 2009 a new management regime of individual vessel quotas (IVQs) was put in force in the world's largest fishery, the Peruvian anchovy fishery. Until 2009, the fishery was managed by a regulated open access system with clear symptoms of the race for fish. We argue that the new regime...

The objectives pursued by governments managing fisheries may include maximizing profits, minimizing the impact on the marine ecosystem, or securing employment, which all require adjusting the composition of the fishing fleet. We develop a management plan that can be adapted to those objectives...

We analyze a policy experiment in an Alaskan commercial fishery that assigned a portion of an overall catch quota to a voluntary cooperative, with the remainder exploited competitively by those choosing to fish independently. Unlike the individual quota system advocated by many economists, the...

Lake Victoria, globally the second-largest freshwater Lake by surface area, houses an artisanal Nile Perch Fishery that directly involves around 200K people. While the 10 whole Lake surface is potentially available to fishing activities, the fishing vessels' operational and technical...
