Food and fraud: On the <i>Codfather</i> and harvest mislabeling Open
We study incentives to mislabel output in multispecies fisheries managed by tradeable catch shares. Firms can save quota costs by misreporting species harvested, as seen in criminal proceedings against the Codfather . We show that price el…
Multispecies Portfolios of U.S. Marine Fisheries: Ecosystem-Based Fisheries Management Reduces Economic Risk Open
Fisheries management has focused on single stocks, not directly accounting for species interactions, and usually only considering economic factors in post hoc analysis. This approach has been successfully applied for many species over many…
NOAA fisheries research geared towards climate-ready living marine resource management in the northeast United States Open
Climate change can alter marine ecosystems through changes in ocean temperature, acidification, circulation, and productivity. Over the last decade, the United States northeast continental shelf (U.S. NES) has warmed faster than any other …
Leveraging data from a private recreational fishing application to begin to understand potential impacts from offshore wind development Open
The development of offshore wind energy in the United States necessitates a sound understanding of trade-offs across ocean uses. Location data on private recreational fishing have been a glaring gap in understanding how society uses marine…
Identifying social thresholds and measuring social achievement in social-ecological systems: A cross-regional comparison of fisheries in the United States Open
In marine social-ecological systems (SESs), environmental and human-induced stressors can push ecosystems from a high-functioning state into a new, often undesirable state (i.e., regime shift) with limited delivery of ecological goods and …

Integrating economics into fisheries science and advice: progress, needs, and future opportunities Open
While the science supporting fisheries management has generally been dominated by the natural sciences, there has been a growing recognition that managing fisheries essentially means managing economic systems. Indeed, over the past seven d…
Assessing the State of Coupled Social-Ecological Modeling in Support of Ecosystem Based Fisheries Management in the United States Open
There has been a proliferation of coupled social-ecological systems (SES) models created and published in recent years. However, the degree of coupling between natural and social systems varies widely across the different coupled models an…
Learning by doing: collaborative conceptual modelling as a path forward in ecosystem-based management Open
Managers, stakeholders, and scientists recognize the need for collaborative, transparent, integrated approaches to complex resource management issues, and frameworks to address these complex issues are developing. Through the course of 201…
There Is no I in EAFM Adapting Integrated Ecosystem Assessment for Mid-Atlantic Fisheries Management Open
Resource managers worldwide are being asked to consider the ecosystem while making management decisions. Integrated Ecosystem Assessment (IEA) provides a flexible framework for addressing ecosystem considerations in decision making. The US…
A simulation study of trend detection methods for integrated ecosystem assessment Open
The identification of trends in ecosystem indicators has become a core component of ecosystem approaches to resource management, although oftentimes assumptions of statistical models are not properly accounted for in the reporting process.…
Addendum: Implementing Ecosystem Approaches to Fishery Management: Risk Assessment in the US Mid-Atlantic Open
Addendum on: Gaichas SK, DePiper GS, Seagraves RJ, Muffley BW, Sabo MG, Colburn LL and Loftus AJ (2018) Implementing Ecosystem Approaches to Fishery Management: Risk Assessment in the US Mid-Atlantic. Front. Mar. Sci. 5:442. doi: 10.3389/f…
Economic and Ecosystem Effects of Fishing on the Northeast US Shelf Open
Modeling tools that can demonstrate possible consequences of strategies designed to operationalize ecosystem-based fisheries management (EBFM) should be able to address tradeoffs over a wide suite of considerations representing the scope o…
Implementing Ecosystem Approaches to Fishery Management: Risk Assessment in the US Mid-Atlantic Open
Fishery managers worldwide are evaluating methods for incorporating climate, habitat, ecological, social, and economic factors into current operations in order to implement Ecosystem Approaches to Fishery Management (EAFM). While this can …
On the precision of predicting fishing location using data from the vessel monitoring system (VMS) Open
Defining fishing grounds based on data from vessel monitoring systems (VMS) has been a widely researched topic in recent years. Much of the research has focused on filtering algorithms for identifying fishing locations from VMS point data,…
Impact of catch shares on diversification of fishers’ income and risk Open
Significance Catch share programs, which allocate a share of a fishery’s annual catch to fishers, are an increasingly popular management approach in the United States and around the world. While catch shares have been shown to increase eff…
Operationalizing integrated ecosystem assessments within a multidisciplinary team: lessons learned from a worked example Open
Between 2014 and 2016, an interdisciplinary team of researchers including physical oceanographers, biologists, economists and anthropologists developed a working example of an Integrated Ecosystem Assessment (IEA) for three ecologically di…
Valuing Ecosystem Services: Oysters, Denitrification, and Nutrient Trading Programs Open
As part of their strategy to meet total maximum daily load restrictions in the Chesapeake Bay, managers have developed nutrient trading markets to curb nitrogen and phosphorus flows into the estuarine system. Historically, nutrient trading…

A Framework for Incorporating Species, Fleet, Habitat, and Climate Interactions into Fishery Management Open
Marine ecosystems are characterized by many complex interactions. Fisheries managers face the challenge of maintaining or restoring sustainability for individual living resources which are affected by both ecological and economic interacti…
