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...

Fisheries management involves many stakeholders with different opinions about how the fishery should be optimally managed. This paper presents a multi-objective bio-economic model, which is able to incorporate the preferences of managers and other stakeholders. The model is a weighted goal...

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 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...
