Estimates of recreational fishing harvest are often unavailable until after a fishing season has ended. This lag in information complicates efforts to stay within the quota. The simplest way to monitor quota within the season is to use harvest information from the previous year. This works well when fishery conditions are stable, but is inaccurate when fishery conditions are changing. We develo...

Many fishery management tools currently in use have conservation value. They are designed to maintain stocks of commercially important species above target levels. However, their limitations are evident from continuing declines in fish stocks throughout the world. We make the case that to reverse fishery declines, safeguard marine life and sustain ecosystem processes, extensive marine reserves ...

Herein we argue that lack of a regular independent review process in U.S. federal fishery management is a serious shortcoming in policy and that such a system should be implemented. Although our arguments specifically refer to federal fishery management in the United States, we believe they may be applicable to other areas of ecological management here and in other countries. Fish-stock assessm...

Among others who point to environmental variability and managerial uncertainty as causes of fishery collapse, Roughgarden and Smith (1996) argue that three sources of uncertainty are important for fisheries management: variability in fish dynamics, inaccurate stock size estimates, and inaccurate implementation of harvest quotas. We develop a bioeconomic model with these three sources of uncerta...

Governance of the world’s marine fisheries is ill-adapted to sustainability. Twenty years after the expansion of exclusive economic zones over most of the continental shelves, fisheries worldwide face problems of stock depletion, declining yields and increasing conflict. Other human activities in the ocean compound the effect. What is wrong? This paper is about the internal workings of fishery ...

Despite increasing importance of marine recreational fisheries, management goals and objectives have not changed from a focus on managing for commercially important objectives such as maximum or optimum sustainable yield. Additionally, recreational fishery stakeholders in several prominent U.S. fisheries have been frustrated by a perceived lack of inclusion of recreational views in fishery mana...

Data from 4,713 fisheries worldwide, representing 78% of global reported fish catch, are analyzed to estimate the status, trends, and benefits of alternative approaches to recovering depleted fisheries. For each fishery, we estimate current biological status and forecast the impacts of contrasting management regimes on catch, profit, and biomass of fish in the sea. We estimate unique recovery t...
