This collection houses the proceedings of the 20th biennial conference of the International Institute of Fisheries Economics & Trade (IIFET), entitled Managing a Changing Environment. The conference took place at Auditorio Mar de Vigo in Vigo, Galicia, Spain, from 18-22 July 2022. Conference organizers were M. Dolores Garza-Gil (University of...
Region policy instruments that transfer funds between jurisdictions are popular tools for mitigating spatial economic disparities. Given the regional aspect of fishing activity, these policy tools often benefit fisheries firms. In this paper, I study the effect of the regional policy area in Norway- a geographical area that is, among...
The small-scale coastal fisheries of Virginia account for a significant portion of the state’s total annual landings and employ thousands of individuals. Despite the value of these fisheries, the number of commercial licenses sold has declined more than 15% since 1994. Declines are attributed to various factors, but indicate potential...
This is an empirical analysis of the Malindi Ungwana Bay prawn fishery in the coast of Kenya. A resource allocation problem is at the heart of the conflict between artisanal fishers and commercial trawlers exploiting the prawn fishery in the bay. The Prawn Fishery Management plan by the government has...

Bermeo is a small town in the north of the Iberian Peninsula, cradle of a purse seiner of undisputed global relevance. Since the time of the Romans, it was recognized for its port, which led it to be one of the first three villages that were founded in the former...
Why did I write a novel? Fisheries operate in complex adaptive systems. A novel can better illustrate the dominant role of system complexity in sector governance. A book may last longer than a paper. I like writing a story, even if it is an illusion within reality.
This paper identifies the effect of Mauritian regulation changes on EU industrial vessels’ fishing activities and their implications for food security. The rich resources of Mauritanian waters have historically been utilized by large foreign trawlers, creating small ripple effects and jobs in Mauritania. However, in 2012, Mauritanian authorities introduced new...
Low-value fish/ fishery by-products are potential economic resources for developing animal feeds. Accordingly, fish protein hydrolyzed technology is an excellent way to provide protein sources for animal nutrition. However, the nutritional quality and applying this new feed supplement are severely related to the production stages and next characteristics of agricultural...
Myctophid/lanternfish is one of the major fish stocks in the Oman Sea. The commercial utilization of lanternfish in the Persian side of the Oman Sea began in 2007. The vessels catching the lanternfish have not been specifically designed and equipped for this fishing operation. In addition, the lack of purposeful...
The European Union has set 2021 as the deadline for having a marine spatial plan in place for all its members. Despite the substantial literature analysing the last four decades of MSP implementation worldwide, the quantification of its economic effects remains at early stages. This presentation presents a methodological approach...
The European Union, under the European Maritime and Fisheries Fund, implement the Community-Led Local Development (CLLD). This programme is designed to address the main challenges faced in the fisheries areas by proposing and testing new solutions by the coastal population. In this sense, Spain plays a key role due to...
Iceland adopted an ITQ system for all of its fisheries more than three decades ago. The system has worked well in increasing the economic performance of the fisheries and, at least seemingly, the enforcement of the TACs. The Fisheries Directorate (FD) is aware of the potential problem of discards and...
Over recent decades, the EU aquaculture sector has been implementing actions towards the minimization of waste as a strategy for increasing the circular attributes of the management system. In this context, it is relevant to develop methodologies to quantify and assess the circularity that will ultimately be achieved by new...
Artificial reefs (AR) were created not only to protect sea bottoms (Lee et al., 2018) and enhance biodiversity namely by stimulating the enhancement of fish stocks (Pioch et al., 2020), but also to attract diving tourism (Shani et al., 2012) or sport fishing enthusiasts (Radonski et al., 2018). In order...
In this paper, we analyze how public monitoring and enforcement (M\&E) efforts affect the success of a collective property right. We develop a bioeconomic model to generate several theoretical predictions, which we test empirically by assembling and analyzing novel data on public patrolling and fishing activity in the Chilean abalone...
Artificial reefs (AR) were created not only to enhance biodiversity (namely by stimulating the increase of fish stocks), but also to attract diving tourism or sport fishing enthusiasts. Industry 4.0 tools – e.g., mobile technologies and cloud computing – can be used for AR monitoring purposes and can serve as...
Policy makers must ensure that regulatory frameworks contribute to the maintenance of resilient marine ecosystems. Recreational fishers add additional pressure on worldwide fish stocks to that exerted by commercial fishing, especially in coastal areas. Fishing tourism have an increasingly stronger presence in areas with growing numbers of permanent residents. Marine...
There is no doubt that policy makers must ensure that the different regulation frameworks contribute to the maintenance of resilient ecosystems that sustain healthy resources for commercial fishers, contributing to the economies that depend on their activity and supply markets with healthy products. However, marine recreational fishing also contributes significantly...
Global Trends: Foreign and transnational ownership (& ownership interests), Complex structures: vertical integration, flags of convenience, joint ventures, etc., Concentration: a handful of corporations controlling global fisheries (Österblom et al. 2015,Carmine et al. 2020). Why Regulate?: Risk of monopolies and market failure, Governance of corporations (i.e., compliance, enforcement), Who captures...
Marine Eco-Label Japan (MEL) is a unique Japanese seafood eco-labeling scheme launched in Japan shortly after the Marine Stewardship Council (MSC) opened its office to evaluate the management of Japanese fisheries resources by large-scale commercial fisheries and small-scale and diverse fishing gear. It became MEL ver. 2 and was approved...
This study was conducted between January 2017 to December 2018 in two fishing communities of Bayelsa and Rivers States, Nigeria. The choice of Imibikiri in Brass local government area, of Bayelsa State and Finima in Bonny Island local government, of Rivers State, was based on accessibility, security, fish production intensity,...
Scientific evidence reveals that renewable resource stock dynamics are subject to uncertainty due to changes in environmental conditions. Despite its critical impacts on management, little is known about the effects of such uncertainty on the formation of regional fisheries management organizations (RFMOs). In this paper, we design a dynamic stock...
Outline: Fishing rights development in Australia, Assumptions - Commercial Fishing (CF) rights security, Experiences - CF rights and other claimants, uncertainty and investment, Options to strengthen resource security & compensation, CF rights - “prime movers” in developing an ocean investment framework, Going forward with the Blue economy, An improved BE...
Despite the use of gear requirements and access restrictions to manage lobster fishery interactions with north Atlantic right whales since 1997, the population is likely below 370 animals. The Dynamic Area Management (DAM) program (2002–2009) used “real time” right whale sightings data to provide temporary protection using closures or whale-modified-gear...

In the past two decades resource economists have made great headway in understanding spatial-dynamic processes in resource exploitation and management. However, despite this progress, there remain large gaps in understanding the spatialdynamics of recreational resources. Here we first develop a general bioeconomic model of a renewable recreational resource use, under...
Local users may invest in managing common pool resources, thereby promoting social and ecological resilience. Institutional or economic limits on access are regarded as essential preconditions for incentivizing local investments, but we show here that investment incentives can exist even under open access. We modeled a recreational harvest fishery in...
Diversification of fishery revenue can reduce interannual variation in revenue and thereby lower financial risk (e.g., Kasperski and Holland, 2013; Cline, Schindler, and Hilborn, 2017; Sethi, Reimer and Knapp 2014; Anderson, Ward and Shelton 2017), Average fishery diversification levels on the US West Coast have been declining over time –...
Study Objectives: IPHC socioeconomic study was a direct response to the Commission’s “desire for more comprehensive economic information to support the overall management of the Pacific halibut resource in fulfillment of its mandate”, Commission’s objective is to develop stocks of Pacific halibut that permit “optimum yield from the fishery and...
In the absence of formal insurance, fishers often ”self-insure” against financial risk due to environmental and economic factors by adjusting fishing activities over species, space, and time. This diversification can be effective (e.g., Kasperski and Holland, 2013; Cline, Schindler, and Hilborn, 2017; Sethi, Dalton, and Hilborn, 2012; Fuller et al.,...
The Cíes Islands show an extremely rich biodiversity, making them the core element of Galicia’s Atlantic Islands, and are an extremely attractive area for the development of small-scale fishing, as well as for tourism and recreational activities, which could constitute a priori a potential risk insofar as maintaining the natural...
Introduction:
SSFs → Own characteristics that often affect prices. First‐sale prices are key for the sustainability of SSF,often price‐acceptors → influence of supra‐local factors (exports, imports, value‐chain forces) and industrial fisheries. Certain local/regional SSF management measures also aim to have effects on this price: fisheries regulation, commercial strategies, labelling, etc....
Context and objective: Beyond leisure and food (sea ES) → MRF boosts maritime economies, but not a formal industry in our economic accounts. EU DCF → increasing focus on MRF, to be considered in commercial fisheries management decisions (CFP). Limitations of traditional approaches (aggregated expenditures,non‐market microeconomics) to assess MRF economic...
Marine recreational fishing (MRF) is a leisure activity and a cultural ecosystem service that, beyond the welfare obtained by its practitioners, has an interesting potential to boost maritime economies. However, it does not represent a formal sector on the national accounts and, in Europe, it lacks a systematic and common...
First-sale prices of fish respond to both local and global drivers, and artisanal fishermen are often considered as price-acceptors due to their limited capacity to influence them, a key issue for their survival and value added creation. However, in artisanal fisheries, the frequent lack of data hinders us from understanding...
The EU framework for the collection and management of fisheries data (EU Reg. 1004/2017) requires estimates of four variables related to capital value and capital cost of fishing fleets, i.e. Consumption of fixed capital, Value of physical capital, Value of quota and other fishing rights, Investments in tangible assets. The...
The valuation marine ecosystem services have been receiving increasing attention in scientific literature, however most of the research is focused in marketed services and does not consider the part of the total economic value. Some services like cultural services that are not direct (touristically) or indirectly marketed as part of...
One pressing economic, societal and environmental issue affecting commercial fisheries is the production of undesirable outputs. In fisheries, undesirable outputs often arise because of economic or regulatory discarding of commercial species and/or the incidentally caught or ‘take’ of protected species, such as sea turtles and marine mammals. In fisheries, undesirable...
Key Takeaway: Understanding this process and factors that influence compliance decisions can help support the development of effective regulations. Importance of consistent observer coverage. Compliance varied by violation choice. Importance of port-level campaigns.
Introduction: The issue of the economic relations between major fishing countries (EU and Asian countries) if of major concern: Overt and tacit vessel subsidies, the asymmetry in the benefits for lower income and higher income countries from fishing and fish processing, LDC EEZs account for around 11 per cent of...
Iran is among the pioneers in the farming of rainbow trout that is mostly up to 1 kg with a production of 173,000 tonnes in 2018, principally used for domestic consumption. Farmers use labour-intensive hand feeding and counting eggs by hand. Imported trout eggs are preferred to domestic eggs as...
This contribution aims to provide an economic assessment of the seabream and seabass industry in the Mediterranean, in order to describe the recent development and current situation of the economy and markets of this industry. It focuses on analyzing the economic and financial structure at different levels of aggregation (industry,...
Nigeria with an annual potential of 2.5 million tonnes of fish from aquaculture produced only 316,727 tonnes in 2015 out of the domestic production of 1.027 million tonnes and total fish demand of 3.25 million tonnes. The government has put in place a lot of initiatives to increase aquaculture production...
The main objective of this study is to assess seafood marketing and pathway in Nigerian coastline (the case of Lagos and Ondo States in the South West, Nigeria).
The specific objectives were to determine the: demographic characteristics of seafood marketers in the study area; gender pathway involved in seafood marketing...
The estimation of production frontiers using revenue as the dependent variable is very common in fisheries research since in multi-species fisheries boats catch several species and their output must be aggregated somehow. The objective of this paper is to decompose revenue efficiency into two components, one due to quantities and...

Fishing systems provide employment, income generation, poverty alleviation, and food security. Management actions have ecological, economic and social implications that must be addressed carefully. The coexistence of small-scale fisheries (SSFs) and large-scale fisheries (LSFs) increases management complexity. Game-theoretical bioeconomic models empower management decisions in such complex systems.
Fishing systems provide employment, income generation, poverty alleviation, and food security. The coexistence of small-scale fisheries (SSFs) and large-scale fisheries (LSFs) increases management complexity. Management actions have ecological and social implications that must be addressed carefully. We applied a bioeconomic game-theoretical model to the four-gear mullet fishery in southern Brazil—one...
Although aquaculture is the food-production industry that has grown the most in recent years, its companies inherently face more variability in their results than companies from other industries This can be explained by the increasing complexity in their decision-making processes, due to the large number of, external and internal, influencing...
This paper studies the price volatility transmission between the different markets along the value chain of fresh anchovy (Engraulis encrasicolus) in Spain. For this purpose, the prices at the ex-vessel market, the wholesale market and the retail market are considered. As a methodology, a Vector Autoregressive Model (VAR) and an...
Decision-making in aquaculture is becoming increasingly complex due to the need of taking into account large volumes of data, and to consider other aspects besides the economic ones, such as product quality or the environmental sustainability, which are sometimes opposing and difficult to integrate. However, the development of simulation and...
Southwest Atlantic (SWA), corresponding to FAO Area 41, covers a total surface area of 17.65 million square kilometres. It spans from 5°N latitude off the coast of Brazil, to 60°S latitude off the coast of Argentina. Most of the area is classified as High-Seas, defined by the Convention of the...
We apply the Fishery Performance Indicators (FPIs) methodology to the Southeast Pacific Anchoveta Fishery off southern Peru and northern Chile. Our basic model of analysis is a production function framework, where the performance outcomes are a result of the available inputs. We measured all FPI categories (outcomes and input metrics)...
While there has been a global proliferation of marine certification schemes aiming to incentivize sustainable fishing in the last decade, the uptake has been comparatively slow in Japan. Suggested reasons include difficulties assessing Japanese fisheries co-management institutions, and reduced profitability from complex seafood distribution networks and mismatched consumer preferences. However,...
Research on small-scale fisheries has largely focused on men’s fishing practices and perceptions and considerably discounted the important contributions by women to household food security and economies (Harper et al. 2013). Studies in most West African countries confirm that post- harvest activities is gendered in nature and revolves around traditional...
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...
Aquaculture has been identified term in the European Union Blue Growth strategy as an activity with high growth potential in the long term. The supply and demand of farmed salmon have been steadily growing in the EU. However, most of the salmon is imported to EU from Norway, while the...
This work reports on the implications of an extreme climatic event among owners of 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 fishing cooperative, have exclusive access to individual fishing grounds...
Future changes in Arctic marine ecosystems will depend as much on global climate change as on our ability to regulate and manage exploitation pressure at sustainable levels. There is a lack of integrated, cross-sectoral ecosystem-based analysis of the Arctic marine management. The analysis is on both the choices for implementing...
Around the world, there are numerous examples of collaborative science -industry partnerships, which provide a bottom up approach to trawl gear development. Many have had better success in implementing selective gears as opposed to a top down approach where selective gears are enforced into legislation. On the other hand, such...
Each year, over 20,000 metric tons of tuna are supplied to the Japanese market, of which 40% are caught by domestic vessels. Although the Japanese tuna market is large, little is known about the supply chain and the Japanese tuna fisheries’ behaviors. In this study, we investigate how Bluefin tuna...
This paper studies whether and under what circumstances, individual fishing decisions in aggregate match the maximum economic yield (MEY) or maximum sustainable yield (MSY) of a fishery. Under experimental economic conditions we provided participants a fleet of boats with a constant marginal cost and a non-linear revenue function. We explore...
The vulnerability approach is an analytical framework used to assess the impacts caused by changes in socio-ecosystems that are often linked to large external natural events. The vulnerability approach is mobilized by the sciences that deal with the management of environmental risks with the aim to determine the conditions allowing...
Individual Transferable catch-Quotas (ITQs) have become a popular management tool to reduce excess competition and foster economic efficiency in marine commercial fisheries. They have increasingly been used in more complex multispecies fisheries, where the by-catch of non-targeted species is common. In these fisheries, the reduction of discards is also being...
We present a positive mathematical programming model (PMP) for Hawaii's longline fishing fleet with the aim of examining the outcome of specific fishery policies. This model expands an earlier model which developed a generalized adaptation of the PMP framework to study fisheries. The current model provides managers with a realistic...
A two-species bioeconomic model is analyzed, but in contrast to most similar models, there is no biological interaction between the species, only economic. The interaction takes place in the market where the quantity of either species may affect the price of the other. Both the sole-owner and the open access...
The Northwest Fisheries Science Center has been collecting cost earnings data since 2003. The Center economists survey all commercial fishing vessels on the West Coast of the United States from San Diego, CA to Blaine, WA. These vessels range in size from less than 40 feet to more than 300...
Choices are often limited as the most popular alternatives reach capacity and sell out; thereafter, selection is over less preferred choices. In the context of nonmarket goods, willingness to pay (WTP) welfare measures provide an estimate of the value of characteristics – often calculated through the modeling of preferences using...
The industry owned trawlers land-lock obligation, originally intended to ensure both greater seasonal distribution of raw material as well as settlement in coastal communities, functions poorly and is being put under pressure. This is due to national and global trends in economics and politics, technological change and changing market conditions....
We develop a model of a multinational firm producing commodities for a global market in multiple locations with location-specific risks and different regulatory standards. Salmon aquaculture and disease outbreaks provide an empirically relevant example. We specifically examine details of the infectious salmon anemia outbreak in Chile in the late 2000s,...
In this paper an unregulated, but not open-access, fishery is studied and it is analyzed how more modern fishing technology may be a mixed blessing not only for the fish abundance, but also for the rent. The model is formulated in section two where it is included a strategic interaction...
The spatio-temporal overlap of morphologically undistinguishable weak and healthy stocks is a major concern for the Pacific Northwest troll Chinook salmon fishery. Regular fishery closures have led to major financial losses calling for alternative regulatory measures. One approach for such complex and pressing socio-ecological challenges is the transition towards transdisciplinary...
Climate change and continued fishing pressure threaten to increase recruitment variability for many wild stocks. Additionally, as many seafood markets are now integrated nationally and globally, individual fisheries may be less insulated from broad macroeconomic shocks. Large inter-annual shifts in fisheries production may have dramatic consequences for economically dependent industries...
