Abstract

The West Coast Groundfish Trawl Catch Share Program was designed to achieve multiple economic goals and objectives, including increasing net benefits, profitability, flexibility, and utilization of harvest allocations. In this article, we leverage seven years of comprehensive cost and earnings data to evaluate progress towards these goals with a focus on harvesters. Our assessment shows that five years post-implementation, net benefits to the nation have doubled, and indicators of productivity and profitability have increased. The fleet that targets Pacific whiting has seen the largest gains, due in part to increases in total allowable catch and the elimination of the race-to-fish. However, increased revenues have not been realized to the degree that was expected for harvesters targeting non-whiting groundfish, partly due to lower than predicted consolidation and relatively low quota utilization. Economic outcomes indicate that tradeoffs exist between certain objectives of the program, specifically between achieving full utilization and flexibility for harvesters. Results are discussed in the context of the design and evaluation of catch share programs for diverse, multispecies fisheries.  相似文献

Abstract

Fishery management measures often aim to regulate harvesting behavior but can have downstream effects on fish processors, output markets, and consumers. Empirical analysis of these impacts is generally limited due to data availability. In this article, we utilize census costs and earnings data to examine operational characteristics and economic outcomes for shorebased processors before and after implementation of the West Coast Groundfish Trawl Catch Share Program. While the overall number of buyers of catch share species along the coast decreased and fish input prices generally increased, patterns in outcomes were different for processors with Pacific whiting operations compared to those that produce nonwhiting groundfish, including lengthened seasonal whiting operations but a decrease in the number of days receiving nonwhiting groundfish. These differences in outcomes illustrate the complexities involved in the management of multispecies fisheries with heterogeneous participants in both the harvest and post-harvest sectors. This review contributes to the fairly limited empirical work on the fish processing sector, which is an integral part of the seafood supply chain and important to the economic resilience of coastal fishing communities.  相似文献

Researchers are turning to alternative data sources (e.g., resource user knowledge) to provide information required for wildlife management. Little is known about the reliability of data elicited from resource users relative to data obtained from user-independent approaches (e.g., observations of fish catches). We test for consensus among three methods that quantify past (1996 to 2007) seahorse catch-per-unit-effort (CPUE) for a small-scale, data-poor fishery in the Philippines: interviews with fishers about good, bad, and typical catch; fisher logbooks; and observations of catch landings. Interviews and logbooks indicated no trends in CPUE through time, consistent with results from the fisher-independent metric, catch landings. Although interview estimates of “typical” CPUE greatly exceeded “typical” observed catches and logbook estimates, interview estimates of “bad” CPUE were comparable. Catch landings estimates for a fisher in a particular year were uncorrelated to what he reported during retrospective interviews. Interviews should be used cautiously to inform specific catch targets (e.g., total allowable catches), although including interview questions about a range of catch experiences (e.g., good, bad and typical), may improve interview-derived data. Logbooks are particularly useful for capturing information about fishing expeditions that produce no fish, which are largely missed by other methods.  相似文献

This article recommends the parallel but separate modeling of nature-based and people-based marine protected areas (MPA) before the design and siting stages of establishing an MPA. Separate but simultaneous modeling of ideal nature and people MPAs permits each to be maximized for its own variables and subsequently compared to identify conflicts and agreements. The case that supports this recommendation is in the Commonwealth of the Bahamas, where the study conducted 572 interviews with people from six traditional settlements in the central Exumas Islands and Cays. The research is focused on why members of these settlements differentially responded to three nearby national MPA proposals.  相似文献

Abstract

The implementation of catch share programs can have socio-economic and ecological benefits, yet may also change the distribution of those benefits within a fishery or across communities. Quota set-asides can mitigate the impacts of these changes. During the implementation of the West Coast groundfish trawl catch share program, 10% of the quota was set aside to be used toward five goals in the Adaptive Management Program (AMP). This quota was to serve as an insurance policy during the substantial changes that were expected to occur under the new management regime. However, this program has not yet been fully developed, in part due to delayed decision-making and the controversial nature of allocating quota. Here, we examine and score six policy options for the AMP against four criteria: effectiveness, flexibility, political viability, and implementability. While each of the options has strengths and weaknesses, those that ranked highly include allocating quota pounds (QP) via the status quo and via auction. Our results highlight the drawbacks of delaying contentious decisions, where uncertainty for participants can constrain operational decisions and subsequent economic gains. We demonstrate the utility of this decision-making framework for evaluating tradeoffs between alternatives, especially for a program with multiple, competing objectives.  相似文献

We model a multi-echelon system where disruptions can occur at any stage and evaluate multiple strategies for protecting customer service if a disruption should occur. The strategies considered take advantage of the network itself and include satisfying demand from an alternate location in the network, procuring material or transportation from an alternate source or route, and holding strategic inventory reserves throughout the network. Unmet demand is modeled using a mix of backordering and lost sales. We conduct numerical analysis and provide recommendations on selecting strategic mitigation methods to diminish the impact of disruptions on customer service. We demonstrate that the greatest service level improvements can be made by providing both proactive inventory placement to cover short disruptions or the start of long disruptions, and reactive back-up methods to help the supply chain recover after long or permanent disruptions.  相似文献

Abstract

Catch share programs can have far-reaching effects on coastal communities and the people that rely on fishing income, including crew members. Analysis of management actions affecting crew wages and well-being is often limited due to a dearth of available data. We examine crew-related outcomes during the first six years of the West Coast Groundfish Trawl Catch Share Program using two unique datasets – a mandatory economic survey and a voluntary social science study. We find that impacts on crew compensation differ from other catch share programs due to prior conditions of the fishery and also vary by the target species within the program. The median number of crew positions per vessel increased slightly, annual crew days decreased, and crew wage as a percentage of revenue was nearly unchanged, even with the introduction of new costs. Median daily crew compensation increased from $514 per day to $776 after implementation of catch shares and annual compensation increased from $33 thousand to $39 thousand. Many crew members expressed a lack of support for the program and job satisfaction did not rise with increased wages and fewer days at sea, indicating that job satisfaction is likely influenced by more than compensation and effort.  相似文献

Shared expectations about marine protected areas (MPAs) might be expected to enhance their effectiveness. This study determined whether members of local communities had common or divergent views about the objectives and indicators of MPA effectiveness. In the central Philippines we used unconstrained and constrained methods to interview people in five stakeholder groups (elders, fishers, leaders, women, and youth) associated with each of 10 community-based no-take MPAs that had been protected between 0 and 21 years. Respondents identified multiple MPA objectives, the most frequently mentioned of which was restoring and sustaining fish populations. The results suggest that MPA age accounts for the greatest level of variation across communities. When unconstrained, progress in enforcement was identified as a key indicator among respondents from younger MPAs while respondents from older MPAs identified increased fish abundance and catch. Although consensus can be reached more easily under constrained conditions, the results derived from unconstrained methods are more revealing of the needs and aspirations of communities. These are likely to contribute more to the search for appropriate management interventions, particularly given that MPAs evolve over time. Hence, the development of MPA effectiveness indicators must be an iterative community-informed process to ensure timely and relevant management interventions.  相似文献
