In many fisheries, the harvesting pattern shows considerable intra-year variation. These fluctuations give
challenges for downstream firms in value chains where predictability and continuity in the flow of production are important. Seasonal harvesting may well be rational from an economic perspective, as migration patterns can give huge variations in catch...
Under the reauthorized Magnuson-Stevens Act (MSRA), US fisheries management councils must specify an annual catch limit (ACL) for each managed species and institute accountability measures (AMs) to ensure that actual harvest will not cause the stock to be overfished. While the details of implementation are still being developed, a set...
It is well known that fishing activities may affect the structure of aquatic habitats and consequently determine the diversity, composition and productivity of the associated biota. The direct effect of fishing
activities is on the habitat structure and the indirect effects occur when the fishing activity initiates shifts in the...
A higher dependence on the resources motivates to community participation on resources management. Uses of common property resources are not benefit to each and every person in equal rate of resources since magnitude of the resources extraction depend on the number of criterion. Selecting of the interest group for the...
In 2001, New Zealand modified its quota management system (QMS) to function as a hybrid ITQ/tax system. Catches in excess of annual catch entitlements (ACE) incur payments, called “deemed values”. The deemed value
system was part of the reforms that separated ACE from quota, which reduced transactions costs for both...
A key issue in fisheries restoration is the speed at which recovery can occur, while still meeting the
economic and social constraints which managers must deal with. This paper uses the viable control approach to examine fisheries restoration and study the tradeoffs involved with the selection of recovery strategies. We...

An increase in the cooperation level is a social welfare improvement, leading to an increase in both the steady-state fish stock and total...
A key element in evaluating fishery management strategies is to examine their effects on the economic performance of fishery participants, yet nearly all empirical studies of fisheries focus on fishing as opposed to processing. However, the economic benefits derived from fish stocks are largely determined by the revenue generated from...
Recent reports of fishery collapse paint a gloomy picture of the ocean's future; perhaps 100% of fisheries from the world's large marine ecosystems (LMEs) will be collapsed in just 40 years. While poor fisheries governance is now widely regarded as the cause, bioeconomic theory and anecdotal evidence suggest that rights-based...
