Strategies for increasing production of goods from working and natural systems have raised concerns that the diversity of species on which these services depend may be eroding. This loss of natural capital threatens to homogenize global food supplies and compromise the stability of human welfare. We assess the trade-off between...
Despite an understanding among consumers that fish is a healthy food, the recommended intake is on average not achieved in many countries. This paper investigates the effect of children in households to the purchase of fish and meat products, using Norwegian household-level panel data on food purchases from 2004 to...
The OECD has been collecting information on fisheries policies for many years. The Fisheres Suppor Estimate (FSE) database represents the latest version of its fisheries policy inventory and classification system. This database contains information on policies in 33 countries (representing about half of global fisheries landings) totalling USD 13 billion...
We provide an initial look at our follow up study on the impact of the Affordable Care Act (ACA) on U.S. commercial fisheries. Earlier work found that in the years immediately preceding the passage of the ACA, North Carolina’s commercial fishermen were more likely to purchase health insurance coverage on...
Fishermen are often advised to be more patient and limit catches now, in order to increase stock size and catches in the future. Such scientific advice is usually based on the maximum sustainable yield (MSY) objective. This biological criterion is often consistent with economic interests at low discount rates. The...
Birds, mammals, and fish eat Atlantic Herring. For the first time, fisheries managers in New England are explicitly considering these, and other, predators when setting harvest control rules for the Atlantic Herring fishery. Based on single-species biological reference points, the herring stock is currently well above MSY levels. However, management...
Hedonic models reveal the marginal implied prices of attributes; these premia represent the intersection of supply and demand for those attributes. Understanding the demand for these attributes is critical for policy analysis that may influence those attributes. While Rosen (1974) proposes a two-step method to recover demand, Kristofersson and Rickertsen...
This work is part of the SUCCESS project (Work Package 4: Competitiveness and sustainability of European fisheries and Aquaculture sectors) funded by the EC (H2020, GA 635188). The dynamics of the value chain in eight different species at the Spanish market has been studied using price integration methodologies. Cases of...
Industries extracting natural resources are confronted with a trade-off between maximizing their income and limiting their impact on the ecosystem they exploit. Commercial fisheries produce negative impact via their pressure on the seabed and the additional mortality from discarding. One approach to limit the discarding impact is to introduce discard...
A suite of metrics may be required to characterize ecosystem status and its resilience. Simplistic models, not accounting for the age composition complexity, can fail in predicting the impacts of anthropogenic activities and may not appropriately evaluate long-term consequences of management. Old-growth age structure is necessary for maintaining long-term sustainable...
Humans are increasingly considered more than simply “part of the ecosystem” by natural scientists and natural resource managers. However, the integration of economic and social sciences into Integrated Ecosystem Assessments (IEAs) is advancing at different rates worldwide. Over the past several years, The U.S. National Oceanic and Atmospheric Administration (NOAA)...
Lake Michigan is the only Great Lake that supports an economically viable salmonid population, but a collapse may be on the horizon. Biomass of Chinook Salmon, the most popular sportfish in the region, decreased by 70 percent between 2013 and 2015. The decline is thought to be irreversible. Managers must...
Stated preference (SP) methods such as contingent valuation and choice experiments are often used to estimate values associated with marine and coastal ecosystem services. However, applications do not always apply best practices, leading to questions regarding the validity and relevance of welfare estimates. This presentation outlines contemporary best-practice recommendations for...
Saltwater recreational fisheries receive little attention compared to their commercial counterparts. Yet recreational fisheries can suffer from many of the same symptoms of open access as commercial fisheries. Regulations designed to allocate a scarce supply, such as seasonal closures augmented with bag and size limits, can result in significant losses...
Quantitative fish stock assessment methods have become increasingly complex. However, the quality of available data may still restrict their applicability, being a particular concern in data-poor situations and where management decisions rely on either commercial fisheries or scientific survey data. In this study we address this issue by proposing a...
A well designed regulatory regime has a number of structural (design) features that will facilitate the achievement of regulatory objectives. For tuna and highly migratory fisheries in areas beyond national jurisdiction, our main objectives are preventing overfishing and destructive fishing practices, whilst enhancing the nutritional, social and economic returns from...
Safety outcomes are one measure of the performance of a commercial fishery. Catch share management, which allocates fishing quota to individual vessels or entities, may reduce economic incentives to engage in risky behavior in the “race to fish”. The Multispecies Fishery in the Northeast region of U.S. is considered the...
Although the formal process of Brexit has started, there is high uncertainty about Brexit’s impacts on the future of demersal mixed fisheries in the North Sea. As migratory demersal stocks (e.g. cod, haddock, hake and saithe) traverse the zones of various countries, one challenging issue is to agree on how...
The recognition of the complex biological and economic interactions occurring in mixed-demersal fisheries have long underpinned the development of fleets- and fisheries-based models and data collection in European fisheries. More recently, mixed-fisheries management plans are being designed and implemented in the frame of the EU Common Fishery Policy. The central...
As net exporter of seafood products, investigation of potential impacts of domestic regulatory measures such as ban on export of certain fish species and ban on demersal trawl fishing on seafood export performance is of eminent practical importance to Oman. To this aim, the main purpose of this empirical work...
In the light of on-going debates about the sustainable agricultural intensification and sustainable development paradigms, this paper examined the linkages between integrated aquaculture-agriculture (IAA) value chain participation dynamics and the welfare of marginalized extremely poor indigenous households using a three-wave household panel dataset from Bangladesh. The distributional effect of IAA...
The landing obligation in Europe has been in place since January 1st 2015. Experiences gained so far point out that a number of institutional initiatives have been launched, but in practice little has changed regarding discard reduction and use of discards ashore. In parallel, the wide-ranging EU research project H2020...
This presentation describes the impact of transitions to catch share management on risk-taking among commercial fishermen in three fisheries. Catch share management has been associated with a decline in the speed and intensity of fishing activities and longer fishing seasons. This is expected to improve safety in fisheries. Using wind...
When fisheries management creates the incentive to “race for fish”, a fishing season can be reduced to only a few days and involve around-the-clock fishing in life-threatening weather conditions. Catch shares management, or the individual allocation of tradeable fishing quota, can improve safety by reducing economic incentives to fish as...
Lake Chapala’s fisheries have been the support of an important economic activity for hundreds of years. At the end of the XIX century, in addition to the fishers, the processing industry employed hundreds of families in the drying and salting of fish. The later introduction of carpe and tilapia forced...
European carp farmers face many challenges in our days. Changed consumer habits, droughts, fish loss through birds endanger their profitability. Our study have selected two European carp regions as case study: The Aischgrund in Germany and Barycz Valley in Poland. Since the new millennium, opinion leaders have introduced initiatives to...

The World Bank’s Global Environmental Facility’s empanelled the Global Think Tank (GloTT) to examine the use of incentive compatible management (ICM) in Area Beyond National Jurisdiction (ABNJ) fisheries. This presentation summarizes the conclusions project that compiled examples of the use of ICM principles in ABNJ fisheries management. This larger effort...
Historically, cod fishing along the coast of northern Norway has been about fishing as much as possible with the least possible resource effort. This traditional logic is rooted in biology (cod’s migration pattern), meteorology (weather conditions) and traditional capture technology (small and not as seaworthy boats). The logic is further...
In this paper we discuss dynamic adjustment paths towards economic optimal steady-state equilibrium in a fishery where two species interact through a traditional predator-prey relation. We set-up a general bio-economic predator-prey model based on the assumption that fishing effort is a public input applied when exploiting the fish stocks. By...
The paper focuses on the combination of the cooperative fisheries management with the non-cooperative literature. It has important modeling contributions by creating a new framework on co-management. The structure of the model is repeated coalition game with the possibility to deviate combined with introduction of a variation of a club...
This paper analyses evidence about fishermen collectively organized bargaining over ex-vessel prices with a monopsony-like buying sector. Government allocation of collective catch quotas to fishermen organizations triggered the voluntary formation of cooperative fishermen’s bargaining associations, while a highly concentrated processing sector started behaving as a countervailing monopsony. This drove ex-vessel...
South Pacific albacore is a species of primary importance in the longline fishery of a number of Small Island Developing States in the Western and Central Pacific Ocean. Despite the fact that the stock is assessed as not being subject to overfishing, nor overfished, economic returns have declined significantly over...
The welfare gains from incorporating ecosystem considerations into fisheries management are unclear and can vary widely between systems. Additionally, welfare gains depend on how ecosystem considerations are adopted. This paper uses an empirically parameterized bioeconomic model to explore the welfare implications of two definitions of ecosystem-based fisheries management (EBFM). We...
This study accessed household fish demand and supply in the coastal Areas of Ondo State, Nigeria. Multistage sampling technique was used.

In general, the fishery is highly profitable. “The Blob”, or the large mass of warm water in the Northeastern Pacific Ocean, was first...
The aim of this research is to identify the effort of the Icelandic fishing fleet since 1950 with focus on the cod fishing fleet in Icelandic fishing grounds. Various historical records and citizen research in Iceland provide unique information and do allow for the total reconstruction of the decked vessel...
A central component of any discrete choice analysis is the selection of alternatives that determine a decision agent's choice set. Failure to properly specify choice sets will generate biased parameter estimates, inaccurate behavioral predictions, and erroneous estimates of policy relevant metrics (e.g., welfare effects of closed areas in fisheries). The...
Almost all recent empirical literatures that study the subjective wellbeing of fishers lack of relevant control as they are only based on surveys among fishers. Therefore, they cannot really answer whether being a fisher generate higher or lower life satisfaction, after controlling for other aspects of life. This study is...
Scarcity of wild-caught seafood has incentivized innovation and growth in aquaculture, especially for species that compete directly with wild alternatives. In the global tuna industry, the most pronounced scarcity is associated with bluefin tuna species (Atlantic, Pacific, and Southern, which serve similar markets). Supply-side factors including overfishing and governance challenges...
Recreational marine fishery is crucial for marine economy and the transformation of traditional fishery. In recent years, it runs into development bottleneck and traditional forms need to change.

The analysis is at the local level where majority of the important actors operate. The...
Any fisheries governance system is made up of policies and institutions in the broad sense of the term that govern the sector. When a system of governance is unsatisfactory, in particular because of the inadequacies and dysfunctions of these policies and institutions, and the way in which public action is...
There are a range of smaller-scale fish farms operating in Ghana producing mainly tilapia and catfish based on extensive (stocking of small reserviours), intensive and semi-intensive (earthen ponds & tanks) techniques. Aquaculture production in Ghana plays a significant role in the economic development of livelihoods of fish farmers and contributes...
This paper presents a deterministic bioeconomic model with a marine protected area (MPA) including both fisheries management and tourism development goals. A weighting parameter is added to the model to allow tradeoffs between management preferences regarding the two sectors affected by the MPA. The theoretical model is illustrated with analysis...
The species-based approach currently implemented in Europe where catch limits (TAC) are set for each stock independently, is not adapted to the management of mixed fisheries that harvest various species. The economic efficiency of those fisheries is often constrained by the existence of « choke species » for which catch...
Most of fish farmed by small scale producers in developing countries is sold directly to local markets without passing through a processing industry. Besides problems related to sanitary requirements, this situation highlights the low added value retained by fish farmers. In Brazil, the integration between small scale fish farmers and...
Women empowerment, an active multidimensional process enabled the women in accessing greater autonomy in decision making , ability to plan their lives. In Kerala women play an important role in the fisheries sector due to their involvement in fishery related activities. Even though women engage in wide range of activities...
Climate change has multi-dimensional impacts on environmental, fisheries, social, economic and development drivers and it necessitates governments in developing appropriate mitigation and adaptation plans.

Drying is affordable preservation method used where poorly developed logistics limit marketing of fresh fish. In Eastern Africa dried Rastrineobola argentea (Dagaa) is an important source of low cost stable dietary protein. The fishery is characterized by high post-harvest losses and products are often of low quality, restricting the sales...
A vessel-based bio-economic model (IAM) is presented and applied to the Bay of Biscay sole fishery to investigate alternative quota management systems from a multi-criteria perspective. For this study, the model integrates several institutional arrangements related to catch share management. The current French co-management system with non-transferability of quota is...
In developing countries, small scale or artisanal fisheries catch data-collection systems, are not performing satisfactorily. This is due to the systems not giving out what is needed for assessing the appropriate fisheries, policy and management decisions, tracking the trends of exploitation of fishery resources and the overall performance of existing...
Climate change has aggravated the marginalized condition of indigenous fishers in the Philippines. It is worth noting, however that the relationship of many indigenous peoples to their natural environment such as the land, the sea, plants and animals incorporates them as part of the same environment. The cultural and religious...
Nigeria’s domestic supply of fishery products falls short of the demand; however, there is a growing aquaculture industry that has come to the rescue in filling the gap between supply and demand. Most of the aquaculture fish farmers are prone to the risk of climate change, since weather and extreme...
Despite the growing popularity of culture-based fisheries (CBFs) associated with village irrigation systems (VISs) in Sri Lanka, there is little knowledge about factors that influence productivity levels. To redress this, primary data from 325 fish farming groups in two districts (Kurunegala and Anuradhapura) are used to estimate a stochastic translog...

Proceedings of the Eighteenth Biennial Conference of the International Institute of Fisheries Economics and Trade, held July 11-15, 2016 at Aberdeen Exhibition and Conference Center (AECC), Aberdeen, Scotland, UK.
This paper presents key lessons from development of a transboundary fisheries co-management (TFC) on Lake Chiuta, shared between Malawi and Mozambique. Since the mid-1990s when fisheries co-management was introduced on the Malawian side of the lake, there had been conflicts between fishing communities from both countries. The conflicts mainly centred...
Despite an extensive literature on food-sharing, little attention has been given to the practice in the context of fish harvesting and consumption. We examine it as a possible, almost inadvertent, source of fishery management and we examine its role in trade. Our model is a simple general-equilibrium model of a small costal economy...
Given the complex and often opaque nature of seafood supply chains, port cities can serve as checkpoints within supply chains to address illegal, unreported, and unregulated (IUU) seafood commodities. Harmonized systems (HS) codes are used at port cities by customs officials to monitor commerce. Concern about IUU activity in capture...
The study examined Fish Value Chain (FVC) in Yola area of Adamawa state, Nigeria. Primary data were collected using questionnaire and were analysed using descriptive and inferential statistics. The results showed that female dominate the fish marketing and processing nodes with 79% and 62% respectively while male (77%) dominate the...
In 2014, developing countries were responsible for 56.5% of total value of seafood imported by the EU; however, their import value only grew 56% relative to 1999. During the same period, China, gained over 300% growth in this market. The EU’s General System of Preferences (GSP) scheme provides duty-free or...
The Gulf of Alaska and Bering Sea pollock fisheries in the U.S. were certified by the Marine Stewardship Council (MSC) in February 2005, yet to date little other than anecdotal evidence exists to suggest whether products from these fisheries have gained market benefits relative to uncertified pollock from, for example,...
In the European market for fish European producers compete with international imports which often can be produced at lower costs. That is why imports of fish are gaining market shares and an economically sustainable production of fish in Europe is frequently questioned. When aiming at increasing European production, consumers play...
Price formation of fish in landing market was studied in Japan to examine price discounts of fish species regularly landed in small quantity. It is often told that buyers tend to offer low bidding prices for fish which have small landing amount in a day because handling and shipping costs...
Recently, several studies have investigated price behaviors of aquaculture and wild fisheries products and related the differences in price fluctuations to production technology, and environmental shocks. Researchers have also documented the evidence of asymmetric price responses along the supply chain of seafood products; however, a feature that has received little...
Economic assessment data in agricultural systems at farm level require a substantial methodology in order to assure result reliability. This paper aims to evaluate the effectiveness of a participatory approach which is being used by the Brazilian Agricultural Research Corporation (Embrapa) in aquaculture. This methodology consists in gathering technical parameters,...
Brazilian aquaculture is undergoing major transformations which have been changing the whole structure of this sector. Except for the shrimp farming industry - which for years already has a high technology production structure - the majority of the Brazilian aquaculture had been characterized for small producers and low level of...
This paper explores, using an historical example, the challenges that small island economies face when they are heavily invested in one or two productive sectors, and where they have had privileged historical access to the resources that underpin those sectors, and suddenly that access is removed or reduced. The Islands...
Commercial fisheries rationalization has promoted economic benefits and accountability to annual catch limits, but most recreational fisheries are managed under regulated open access with relatively poor catch accounting, short and unpredictable seasons, and persistent overharvests. For many mixed-used fish species, recreational fishing represents over half of total fishing mortality. Yet...
Gulf of Mexico oyster safety is a significant health issue, ranking as the fourth leading cause of foodborne death in the United States. Seafood traceability is an approach that can be used to increase oyster safety. Traceability is the ability to follow seafood through all stages of production, processing and...
We develop a theoretical model to address the effects of different market structures on the ex-vessel prices and consequently how this would impact the risk-sharing mechanism for harvesters and processors in fisheries. We focus our research on two market structures, price-at-landing (PL) and post-season pricing (PS). PL market structure is...
The paper devises an integrated ecological–economics–social model to assess the implementation of ecosystem-based fisheries management in the Pearl River Estuary (PRE) in the South China Sea (SCS). In particular, this paper presents the development of an integrated model, which links a regional economics social accounting matrix (SAM) model to an ecological...
The parrotfish and lobster fisheries play important ecological functions. Besides the ecological functions, the fisheries are important market assets exploited for food and income and cater for different markets. Because of the differences in the value of the two fisheries, competitive strategies employed by fishers and traders and the implications...
The positions of Japan and Australia have been in sharp contrast over whaling; Japan seeks to expand whaling and is not concerned about protecting whales while Australia attempts to halt whaling and strengthen whale conservation. In this study, we hypothesize that this sparked difference reflects different levels of willingness to...
An international conflict between pro- and anti-whaling countries has been a concern. While many Western countries condemn whaling, Japan conducts ‘research whaling’ under the special permission of the International Whaling Commission (IWC) along with Norway and Iceland, who also engage in commercial whaling. Especially Japan and Australia have been divided...
In order for the fisheries to recover from the Fukushima Disaster, we investigated that how much the Japanese consumers are willing to pay (WTP) for seafood caught in Fukushima and the adjacent regions. Since market data of Fukushima seafood are not available, we conducted hypothetical survey (conjoint analysis) to measure...
Demand for unshelled oysters has recently risen in Japan as oyster bars gain popularity among consumers. This study undertook consumer preference research to evaluate a new brand of unspawned oysters, Amakoro, compared with conventional oysters. We surveyed the willingness-to-pay (WTP) for both oyster types as well as consumers evaluation of...
