Fisheries models are generally built to assess the dynamics of a resource with a given fishing mortality
which level can be decided by some “decision maker” and/or which can be an observed process, e.g. times series proportional to some observed values of fishing effort. In these cases, the resource dynamics...
Studies on compliance with fishing regulations have looked at fishery crimes for which the offender faces a one-period
decision problem of maximizing an expected utility. Moreover, the returns to the crimes are uncertain
because the offender may lose them if caught. This paper extends these models by considering a fishery...
Co-management has attracted considerable attention around the world, including in Vietnam. However, debates on the concept of community-based management (CBM), co-management (COM), and community participant management in Vietnam are increasing, and the abundance of projects in Vietnam has now become a major constraint. Although most pilot co-management projects are recorded...
This report presents the results of bio-economic assessment studies of the Bohai Sea & the Yellow Sea and the associated fisheries management. The studies, which were facilitated through workshop with the participation of international experts, included fisheries resources rent assessments and causal chain analysis to determine the rent losses in...
Australian Commonwealth fisheries have adopted maximum economic yield as a target reference point. A bioeconomic model has been developed for one key fishery - the Northern Prawn Fishery - and is used in the provision of management advice. The development and application of this model has highlighted some challenges for...
As part of the ecosystem approach to managing fisheries and other uses of marine ecosystems, there has been a growing call for the development of integrated assessment tools to support the provision of both tactical and strategic management advice. Of particular importance in this domain is the development of models...
Ideally, we seek to develop perfectly integrated ecological-economic models, drawing on the best data, modeling and knowledge of each of the disciplines, into one coherent model to inform policy. The realities of achieving such are thwarted by data and model compatibility issues. For example, ecological data may be available on...
This paper proposes a formal analysis of the discarding issue including the sorting labour costs. Empirical evidences from an application to the Nephrops fishery in the Bay of Biscay show that sorting is an important time consuming activity on board and a factor of discarding. However existing literature does not...
This paper analyzes the behavior of fishing households under individual transferable quotas (ITQ) system based on Singh, Squire and Strauss household model. ITQ system is sought to be the optimal fishery management regime in terms of economic efficiency. However, preceding theoretical analyses only considered implementing ITQ to a well established...
The National Marine Fisheries Service (NMFS) is mandated by law to analyze the benefits, costs, and economic impacts of the recreational fisheries policies it promulgates. NMFS has developed single species models that predict welfare and effort changes stemming from changes in various recreational regulations. Little is known, however, about angler...
