While rights-based management is generally purported enhance economic efficiency in fisheries and reduce over-capitalization, the social and economic outcomes due to this regulatory regime are less comprehensively understood. Relatively recently, industrialized and export-oriented Latin American fisheries began adopting individual transferable quota (ITQ) regimes to recover collapsed fish stocks. While these...
This talk will introduce this special session on coastal and marine spatial planning (MSP). An overview of how MSP is interpreted and implemented in the United States at different geographic scales will be discussed. An emphasis on data and research needs will be given as well as context for the...
Fisheries management currently claims for fisheries governance (FG), a more balanced scheme that proposes to share the power among government, civil society and economics. In Mexico and other developing countries, the lack of operational regulations has delayed its implementation. Several authors state that topological analysis is useful to identify key...
Eco-labels have been developed to face the difficulties faced by States in managing fisheries. They promote the voluntary adoption of sustainable practices, through market differentiation of sustainably produced items. In fisheries, the Marine Stewardship Council (MSC) is the most commonly used eco-label. The label is presumed to increase the social and...
The UN Voluntary Guidelines for Securing Small-scale Fisheries, along with the Voluntary Guidelines for Responsible Governance of Tenure of Land, Fisheries, and Forests, recognize the role of secure tenure in ensuring the livelihoods, well-being, and basic human rights of small-scale fishing (SSF) communities. Rights-based management (RBM), which works to secure...
Recently, the U.S. Departments of Agriculture (USDA) and Health and Human Services (HHS) recommended that pregnant and nursing women consume at least 8 to 12 ounces of seafood per week as part of a well-balanced diet. Thus, the seafood market has been flooded with health benefit/risk information targeted at women...
Marine spatial planning (MSP) is a process that planners can use to make decisions about different, sometimes conflicting, ocean uses. The process is intended to be participatory and to facilitate the sharing of information about multiple uses of the marine environment. In the U.S. an important component of MSP is...
In the last several years a number of U.S. policies and directives have laid the foundation for Ecosystem Service Valuation (ESV) to be incorporated into ecosystem-based management (EBM), the current management paradigm for U.S. oceans and coasts. In 2010 the Final Recommendations of the Interagency Ocean Policy Task Force instructed...
This work reports on how resource rent is distributed among owners of exclusive fishing grounds in the spiny lobster (Panulirus argus) fishery of Punta Allen, Mexico. This MSC certified small-scale fishery is co-managed through Territorial User Rights. Members of the local fishing cooperative, have exclusive access to individual fishing grounds....
A behavioral study on fishery participation and fishing location choice for the West Coast Salmon fishermen was undertaken to determine the effect of salmon fishery closures on the distribution of fishermen across alternative fisheries and fishing locations. A dataset describing fishing trips from West Coast salmon vessels from 2005 to...
Acute hepatopancreatic necrosis disease (AHPND), initially referred to as early mortality syndrome (EMS), is an emergent bacterial disease that has resulted in substantial economic losses for the global shrimp farming industry. Its occurrence was first reported in China in 2009, rapidly spreading to Vietnam, Malaysia, Thailand, and eventually Mexico in...
This paper is the result of a project that began with NAAFE 2015 special session on Fisheries Certification, which asked what forces are driving the market for sustainable seafood. Many previous studies looked at consumers' demand, but in this paper we looked at the entire supply chain (from producers to...
The trans-boundary migration of fish stocks creates spatial externalities, and hence, makes international cooperation beneficial. This study provides a model for the management of straddling and highly migratory fish stocks and examines the relationship between fish migrations and the benefits from cooperation. Previous studies on trans-boundary fish stock management have...
When evaluating potential government interventions economists often consider whether a proposed policy is efficient. However, changes in policy can also result in changes in wealth. When politically influential individuals or groups see losses, efficient policies can become politically infeasible even if they increase wealth in aggregate. This paper examines political...
The objective of this paper is to provide an analysis of the current state of fisheries subsidies worldwide, and how they are likely to affect the sustainability of fisheries. More specifically, I will review previous investigations of global subsidies issues, and give a brief overview of the impact of subsidies...
The goal of this research was to characterize the trade-offs between profitability and sustainability when managing a valuable commercial fishery. The Florida finfish fishery generates over $75 million in annual dockside value; the snapper-grouper complex constitutes over half of that total. Currently, federal stock assessment procedures focus on stock size...
This research combines a utility-theory consistent model of demand for recreational fishing trips with an age-structured stock dynamics model to provide policy relevant advice to managers of the groundfish fishery in the Northeast United States. We provide an overview of the model and describe the challenges encountered with using this...
The Biodiversity Impact Mitigation (BIM) hierarchy provides an overarching conservation framework for bycatch reduction, and more broadly for biodiversity conservation. This framework includes four steps, which are implemented sequentially to: (i) avoid and (ii) minimize impacts; (iii) rehabilitate/restore impacted biodiversity; and (iv), compensate such impacts, usually elsewhere. The first three steps...
The vaquita, a critically endangered marine mammal, is a bycatch to shrimp strawl and gillnet fisheries in the upper Gulf of California. Reducing vaquita bycatch, however, is complex. The fisheries are smaller-scale and major contributors of income and employment to coastal communities. Although tourism is increasingly important, fishing remains an...
This presentation provides an overview of a session presentation held at the NAAFE Forum 2017 in March, 2017. The title of the session was: Rights-Based Management. The title of the presentation was: We Need to Restore Ourselves First: The Story of El Manglito.
In this paper we characterize changes in the level and spatial distribution of fishing effort during the extreme ocean temperature event known by oceanographers, climate scientists, and the public as “the Blob.” The Blob was an unprecedented marine heatwave that occurred off of the Pacific Coast of North America from...
Achieving economic viability is an important goal when it comes to developing policies for sustainable fisheries management, especially for small-scale fisheries (SSF). SSF are vital for many coastal communities, however, often economically and politically marginalized. Here, we develop and estimate what we denote as ‘basic economic viability’ of SSF, using...
Fisheries subsidies have been roughly estimated to be as high as $35 billion worldwide, of which about $20 billion have been categorized as capacity-enhancing subsidies that directly contribute to overfishing. Since 2001, the necessity for reforming fishing subsidies has been part of the discussions in the World Trade Organization (WTO)....
Influence of the Skipper Effect in fishing efficiency of a mixed fishing fleet, looking at a Mexican case study. Understanding the factors that define technical efficiency in a fleet is a requirement to define strategies to regulate the fishing pressure. In industrial and semi-industrial fleets more weight has been given...
The Resource Evaluation and Assessment Division’s Social Sciences Branch (SSB) in the NOAA Northeast region is preparing for an external review in 2017 to evaluate its programs alignment between the strategic objectives of SSB, NEFSC, NMFS, and NOAA. In previous SSB and NEFSC wide reviews, much attention has been drawn...
The Gulf of Mexico Red Snapper IFQ Program (Program) was the first catch share management program implemented in the Gulf of Mexico. IFQ management was implemented to reduce overcapacity and eliminate the problems associated with derby style fishing. The Program was successful, the number of vessels harvesting red snapper decreased...
Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...
As anthropogenic changes interact with natural climate cycles, the variability of marine ecosystems is likely to increase. This variability influences the behaviour of fishers, which can affect the profitability and sustainability of stocks and may have wider economic and ecological effects. We use data from the US West Coast salmon...
Fishing for Pacific Hake Merluccius productus in the Gulf of California is carried out by shrimp trawlers. When the shrimp fishing season ends, these boats shift to catching Pacific Hake and other finfish. The Pacific Hake fishery is relatively new and has the potential to grow as an industry. Therefore,...
A significant proportion of catch by artisanal fishers in Ghana is sold through wealthy middle-women, known as “fish mothers,” who often pre-finance fishing trips. This study examined the determinants of catch sales through fish mothers. Data used came from artisanal fishermen at major coastal fishing communities in Ghana. The effects...
Seafood markets are the inflection point in the fish-to-food transformation, and act as windows into revealed consumer preferences for seafood selection. These preferences have far-reaching implications for fisheries management, food security, and marine conservation. This study reveals consumer preferences for seafood in San Diego County by quantifying the relationship between...

Analyzing the socioeconomic impacts of fisheries management requires a distinctive array of information that has so far been less developed than the biological data used in stock assessment. In the case of the European Common Fisheries Policy the project SOCIOEC studies the socioeconomic effects of the new European fisheries management...
As part of an effort to describe the recent history and socioeconomics of a small commercial fishery, we were provided access to a large, multi-faceted data set. In using those data, we faced a number of challenges related to data management, data protection and confidentiality, and needed to develop effective...
Bering Sea/Aleutian Islands (BSAI) groundfish fisheries are hugely productive with 2008 – 2014 harvests averaging 1.6 million tons and generating $1.95 billion annually. The BSAI also hosts a commercial halibut fishery with 2013 landings of 3,500 tons and revenues of $41.5 million. Downward trends in halibut biomass combined with continued...
Ecologists warn that the rapid evolution occurring as a result of high-intensity commercial fishing could have potentially disastrous economic and ecological effects. The evolution of economically relevant life-history traits in fish, which can occur due to the harvesting pressure from commercial fisheries, can irreversibly diminish fisheries yields and ecological services....
Choosing a policy instrument is a strategic choice. In the case of fisheries interactions with marine mammals and sea turtles, the preferred policy instrument has been a command-and-control approach such as effort reductions (e.g. area closures) and/or technology standards (e.g. gear modifications), even though market based approaches are available. Since...
Recreational fishing for popular species like red snapper and grouper in the Gulf of Mexico follows a pattern that is well known in commercial fisheries: fishing under regulated open access promotes short, unpredictable seasons, shrinking bag limits, and large and persistent overharvests. With federal fishing seasons at all-time lows and...
Individual Transferable Quota (ITQ) systems have been used to control harvests and increase fisheries’ economic efficiency; however, they do not eliminate competitive fishing which can result in stock and congestion externalities that are especially apparent when resources are spatially heterogeneous within the controlled region of the ITQ system. These externalities...
The opening and closing of the shellfish harvest area inevitably influences the market, particularly the exvessel prices that harvesters receive. Without a better understanding of shellfish market and its behaviors, it is impractical to determine the impact of management policies on the market as well as the fishery resources. Using...
This paper investigates the impact of fishery subsidies on resource stocks in 23 OECD countries for the period 1996-2011. Country level subsidy data is matched with a resource stock index prepared by the Sea Around Us Project. Since the impact of subsidies is likely to vary by type, subsidies are...
In 2013 a stock of sea cucumber (Isostichopus badionotus) was discovered in northern shelf of Yucatan. A survey calculated a biomass of 17,600 tons. The species has an attractive price for local fishers, therefore, in order to avoid the “race for sea cucumbers” and the collapse of the stock, authorities...
From 2000 onwards, the United States saw an increasing trend for the shellfish aquaculture practices especially along the Northeast coast. Despite the supporting majority of public regarding the shellfish aquaculture operations, these operations are sometimes opposed by local communities claiming the devaluation of housing property due to the construction of...
Overfishing and the destruction of small-scale fisheries in developing countries — particularly through the use of illegal fishing gear — is a pressing issue. Policymakers and local community leaders often suggest fines and enforcement mechanisms to reduce the use of illegal fishing; however, the response of fishery participants to “bans”...
Individual transferable quotas (ITQs) have been used in British Columbian fisheries management for more than 25 years. When they were implemented, few restrictions were placed on who could own or lease quota. As a result, many retiring fishermen retain quotas to lease or sell to processors and corporations rather than...
The Alaska recreational charter boat sector has undergone significant change in recent years due in part to several regulatory changes in the management of the Pacific halibut sport fishery, including a limited entry program, harvest controls specific to the charter sector, and a Catch Sharing Plan (CSP) implemented during 2014....
As fisheries management becomes more collaborative by seeking input and involvement from stakeholders, it is important to understand and address the diversity of those stakeholders. Gulf Coast fisheries communities include diverse racial and ethnic groups, particularly a large number of Vietnamese Americans involved in all aspects of the seafood industry....
Ecosystem services (ES) represent a way to represent and quantify multiple uses, values as well as connectivity between ecosystem processes and human well-being. Ecosystem-based fisheries management approaches may seek to quantify expected trade-offs in ecosystem services due to actions such as restoration and gear restrictions, or due to changes such...
Fishing years 2012 -2013 brought declines in socio-economic performance for the Northeast groundfish fishery. Severe reductions in catch limits for key species such as Atlantic cod have constrained fishing behavior and declining groundfish revenues cannot be offset by non-groundfish revenues earned by the fleet. Little is known about the way...
Over recent years, fisheries managers have been going through a paradigm shift to prioritize ecosystem-based management. With this comes an increasing need to better understand the impacts of fisheries management decisions on the social well-being and sustainability of fishing communities. This paper summarizes research aimed at using secondary data to...
The for-hire sector plays a significant role in providing recreational fishing opportunities for Atlantic highly migratory species (HMS) such as tuna, billfish, swordfish, and sharks. Because of the high cost of equipment needed to pursue HMS, many saltwater anglers find chartering a for-hire vessel to be the only affordable alternative....
Two species of the Indo-Pacific lionfish (Pterois miles and P. volitans) have rapidly expanded throughout the Gulf of Mexico, mid- and south Atlantic and the Caribbean following their introduction to Florida coastal waters during the mid-1980s through releases from marine aquaria. There is overwhelming scientific agreement on the threats that...
Several factors currently threaten blue crab (Callinectes sapidus) in the Chesapeake Bay. In addition to poor water quality, degraded habitat, and shifting environmental conditions, derelict gear has recently been recognized as a significant source of mortality for this economically and culturally significant species. From 2008 through 2014, commercial watermen in...
Fisheries management is increasingly being conducted at finer scales of spatial resolution. The spatial distribution of fish stocks is recognized as being an important aspect of stock abundance and spatial management tools, such as marine reserves, have become common. Information on the spatial distribution of fishing effort is critical to...
We empirically disentangle the efficiency mechanism of revenue sharing, in which a group of harvesters shares catch and/or revenue among members of a fishery cooperative, by incorporating the influence of social capital. In addition to each of revenue sharing and social capital influencing a fishery independently we hypothesize social capital...
The traceability practices of 48 seafood businesses were assessed as part of an evaluation of nine global seafood value chains (from harvest to retail). The research was conducted through direct interviews and written surveys in order to assess the reasons why traceability systems were used to strengthen business performance. The...
Climate change and continued fishing pressure threaten to increase recruitment variability for many stocks globally. Shifts in the inter-annual stability of an exploitable renewable resource may have dramatic consequences for the industries and communities which depend upon them. In this talk, the link between resource volatility and industry structure is...
Data scarcity and weak institutional governance make the implementation of top-down, quota-based fisheries management in much of the developing world’s fisheries difficult. An alternative to quota-based management is the use of space-based rights such as territorial use rights fisheries (TURFs). In spite of wide spread use of TURFs as a...
National Standard 1 states that a primary function of fisheries management in the single stock case is the determination of the annual allowable harvest, and it is based on the selection of a target stock size and a control rule that will specify a harvest path that that will cause...
Cooperatives in the Rights-based Fisheries Management have the potential to overcome some of the limitations of Individual Transferrable Quotas. The New England groundfish sector management, a new regime under which fishermen can voluntarily form sectors with each sector constrained by a total allowable catch or Annual Catch Entitlement (ACE), is...
The Pacific sardine fishery is shared but independently managed by three nations: Canada, USA and Mexico. As a result, potential conflict scenarios may arise. A stochastic optimal control methodology is presented to analyze potential conflict scenarios by first considering a deterministic logistic stock growth function and adding a stochastic term,...
As fisheries management becomes more collaborative by seeking input and involvement from stakeholders, it is important to understand and address the diversity of those stakeholders. Gulf Coast fisheries communities include diverse racial and ethnic groups, particularly a large number of Vietnamese Americans involved in all aspects of the seafood industry....
During the first three years (2007-2009) of the Gulf of Mexico red snapper IFQ program most quota lease trades were local, involving fishers that lived in the same communities. In 2010, the red snapper quota lease market changed as more IFQ participants began trading quota with fishers from different regions...
Ecosystem externalities arise when one use of an ecosystem affects its other uses through the production functions of the ecosystem. We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon general ecological principles and is calibrated...
Almost one half of the EEZs of the world are subject to so-called foreign fishing arrangements (FFAs), in which foreign fishing states (distant water fishing states in particular) gain access to EEZs under access arrangements with the relevant coastal states. The FFAs may take the form of “fee fishing” arrangements,...
Recreational fishing for popular species like red snapper and grouper in the Gulf of Mexico has followed a familiar pattern to that observed in many commercial fisheries: fishing under regulated open access has promoted a “race to the fish” with cascades of shorter seasons, shrinking bag limits, and significant fishery...
In this paper we measure the value of sanitary restrictions in terms of forgone profits. For this we model the trade-off between biosecurity and profits in the salmon aquaculture industry. We introduce the concept of “sanitary desirable volume” of the salmon industry, as a goal in a bi-objective model. We...
Over the last decade direct exports to China and Hong Kong of Pacific Geoduck have grown to encompass more than 80 percent of U.S. geoduck production. In December 2013 China shut its doors to U.S. geoduck over possible arsenic contamination and imports from the U.S. fell from over 250 MT...
"Rationalization” or the change to catch share management in fisheries has been shown to lead to the slowing of fishing activity, input and effort consolidation, cost savings, as well as new market and product development. The effects of rationalization on fishermen’s behavior become more complex when one accounts for the...
Electronic monitoring (EM) systems hold promise for the future collection of fishery-dependent data, either to supplement human at-sea observers or replace them. Several pilot studies have been conducted on EM in the New England groundfish fleet, though there are still on the water operational and shore-side protocols to further test...
Fishing impacts biodiversity on multiple levels, potentially resulting in unintended feedbacks to economic performance of the fishery over time. For example, targeting observable traits within a population can impact genetic diversity, targeting populations within a species can impact population diversity, and targeting valuable species can impact biodiversity at the ecosystem...
Fisheries sustainability is a much sought-after goal. Yet, “sustainability” is often too ambiguously defined to be of much practical guidance to policymakers. Furthermore, fisheries managers are increasingly expected to assess and manage fisheries in an “ecosystem-based” manner – accounting for the ecological interdependencies of species and their coupling with the...
In 2011 an individual fishing quota (IFQ) system was implemented for the limited entry trawl component of the Pacific groundfish fishery in the US. The IFQ system allocates quota shares (QS) for 29 IFQ stocks and individual bycatch quota (IBQ) shares for Pacific halibut. Each year quota shareholders are issued...
In an environment of limited resources and expanded management expectations, fisheries regulators face hard decisions about how intensively to regulate different stocks. The Fishery Management Councils are required to regulate harvest of all stocks in a sustainable manner, but have discretion on how much regulatory effort to invest in individual...
A brief overview of changes in the distribution of permanent entry permits in Alaska’s limited fisheries is provided in this presentation. From 1975 to 2014, 79 permit types have been issued in 65 fisheries. This presentation provides an overview of Alaska’ limited entry program, gives statewide data and some fishery-specific...
The paper analyzes a situation in which the fishing fleet is subject to restrictive regulation regarding the harvest of its primal target species due to biological overfishing that in turn reveals a high level of overcapacity. The goal is to model fishermen’s expectations and likely responses to the government initiated...
Multispecies fisheries pose a considerable management difficulty with respect to quota allocation between species. Externalities of direct control over the harvest may include, among others, creation of unbalanced predator‐prey relationships in the environment. That, in turn, may affect the individual economic incentives of fishing vessels. Combining economic and ecological factors...
Many of the tangible benefits of catch share programs (e.g., reducing overcapacity) are dependent on the trading of shares. Additional trading-related questions (such as whether landings will change port or be concentrated geographically) are also important to the overall evaluation of a fishery, but are often asked only during post-implementation...
Purchases made by marine recreational anglers are an important source of economic activity in coastal areas around the United States. In recognition of the economic contributions anglers make to coastal state economies, NOAA Fisheries conducts surveys every three to five years in order to gather data on expenditures made by...
The Baltic fishery is managed under the European Union Common Fisheries Policy (CFP) which defines procedures for setting annual total allowable catches (TAC) for major commercially harvested species. TACs are given as fixed shares to each member state by applying the principal of relative stability. Poland uses non-tradable individual vessel...
New Bedford’s share of Atlantic sea scallops landings and revenues increased from 44% in 1996 to 67% in 2013. Explanations for industrial agglomerations often focus on the relative importance of natural advantage and economies of scale or scope. We use the absolute and relative Theil indices of disproportionality to examine...
From 2012 through 2013, NOAA Fisheries Service conducted a study to collect participation, effort, and expenditure information related to ocean recreation activities in the United States. This study collected information from all 50 states and the District of Columbia in six, two-month waves. There were eight ocean recreation categories of...
Sablefish (Anoplopoma fimbria) are distributed from Japan to Baja California. Alaska is the world’s principal supplier of sablefish with the majority of commercial landings occurring in the Gulf of Alaska and the Aleutian Islands. This demersal, long-lived fish is in one of Alaska’s highest value commercial fisheries. In terms of...
This research analyzes the effects that a redistributive fishing quota policy, within a collective rights quota assignment system, might have on the profits and employment of artisanal fisher organizations. The Chilean authorities have been pursuing a deliberate quota redistributive policy between ship-owners of different vessel categories. This policy has affected...
Atlantic sea scallop fisheries in Iceland and the United States have been subject to outbreaks of ‘gray meat’, a disease caused by infestation by a new species of apicomplexan parasite that causes progressive myodegeneration of scallop meats that kills scallops and reduces recruitment. Due to reduced exvessel value, fishermen discard...
In this paper we study whether environmental bureaucrats share preferences for environmental policy with the general public. We use the choice experiment method to elicit preferences for improvements in coastal cod abundance along the Swedish West coast. This is done for the general public, Swedish EPA (SEPA) bureaucrats, and for...
The North Atlantic U.S. groundfish and scallop processing industries are a tale of two fisheries. The groundfish processing industry has suffered a steep, almost continual decline in landings starting in 1984 that resulted in 2014 landings that were only 16% of 1983 landings. US scallop landings increased from 5 million...
Alaska is the largest seafood producing state in the US. In 2013, Alaska landed 1.88 billion USD worth of seafood, with a volume of 2.63 million MT. This consists of 34% of the total value and 60% of the total volume landed in the US. Of the top 20 fishing...
The great earthquake that hit Japan on March 11, 2011, triggered a nuclear power plant accident. As a consequence, many marine product processing industries and fishery resources were damaged. This paper discusses the determinants of the rumors related to the radioactivity, which seem to affect the purchase decisions of processed...
Commercial fishing is generally hazardous, but some types of commercial fishing are more dangerous than other types. Since much of the fishing industry is composed of small family-owned businesses, commercial fishermen have to rely on the private health insurance markets, health insurance offered through a landside job, spouses’ plans, social...
The Agricultural Act of 2014 (Public Law 113-79) amended legislation regarding the U.S. catfish inspection program to include “all fish of the order Siluriformes,” encompassing imported species: basa, tra, and pangasius. Furthermore, the amendment finalized the transition of catfish and catfish-like product inspection responsibilities to the USDA Food Safety and...
The potential economic impact of a fully developed mariculture industry in Alaska is not well understood by industry or policy makers. It is also not entirely clear what is needed to move from Alaska’s current micro industry (approximately $500,000 in annual sales) to a fully developed industry. In general, the...
Maryland, Pennsylvania, Virginia, and West Virginia have all developed nutrient trading programs to defray the cost of achieving mandated nitrogen load reductions in Chesapeake Bay, and there is increasing interest in the role oysters can play in generating credits. A number of bioeconomic models highlight the impact these credits have...
