Multiobjective decision analysis (MDA) is a useful assessment method when fishery managers need a systematic investigation of the trade-offs involved in the selection of alternative policy options. An important class of techniques within MDA is vector optimization, consisting of mathematical programming models with vector valued objective functions. From the management...
In this paper, we study the short run price dynamics of imported fresh, farmed Atlantic and Pacific salmon on US regional markets. An Error Correction framework is used to specify a short run model. The results show a substitute relationship among the different salmon species in that an adjustment process...
This document provides an overview of a presentation held during the Industry and Policy Day at the IIFET 2016 Scotland conference in July 2016. The presentation was part of Session B2: Implementing the Landing Obligation in the Reformed CFP - Practical Challenges and Effects on Fishing Businesses - 2016 Story...
This paper deals with the sustainable management of a renewable resource
based on individual and transferable quotas (ITQs) when agents differ in terms of
harvesting costs or catchability. In a dynamic bio-economic model, we determine
the conditions under which the manager of an ITQ system can achieve sustainability
objectives which...
Canned tuna is a typical international Agribusiness-based product. The most representative flow of the product is such that the tuna is processed in a firm in the developing country of the tropical area where the canned material, namely tuna and skipjack, is caught and landed. Canned products furnish standardized features...
Organizers convened an international workshop to address training necessary to produce effective managers for 21st century fisheries. The workshop involved government, industry, academic, and nongovernmental organization (NGO) leaders from Oceania, North America, and Europe. They addressed vision and management challenges of 21st century fisheries; requisite skills and knowledge; current training...
Finland became a member of the European Union (EU) in 1995. After that the food market has changed radically. At the same time the eating away from home has become increasingly common. The aim of this
paper is to describe the development of fish consumption in the Finnish catering service...
Small-scale fisheries make key contributions to food security, sustainable livelihoods and poverty reduction, yet to date the economic value of small-scale fisheries has been poorly quantified. In this study, we take a novel approach by characterizing post-landing trends of small-scale fisheries resources and estimating their total economic value, including both...
This paper explores the reasons why the ties between harvesting and processing have been severed in the
Icelandic fisheries in recent decades, and traces the role played by better transport, the emergence of
domestic wet-fish markets, and the introduction of freezing trawlers, as well as other factors in this
development....
The world’s fisheries are widely considered to be in ecological crisis. One governance solution is private standards, including ecolabelling. The conventional logic is that ecolabels meet consumer demand for ‘sustainable’ seafood, with good players rewarded with price premiums or market share and bad players punished by reduced sales. Empirically, however,...
Cameroon is a country of Central Africa, with 402 km coastline where occur intense industrial and small scale marine, multispecies/gears fishing activities. Fishing accounts for 5.2% of GDP in the primary sector and 1.7% of GDP. The Ministry of Livestock’s, Fisheries and Animal Industries is responsible of the fisheries policy...
In developed – and some less-developed – societies, managing an “open access,” renewable
natural resource sector generally involves taxes, quotas, or other government or community
restrictions. But some cultures, especially in their early years, have taken a different approach,
one that involves transfer of part of the output of the...
Japan is the number 1 country in the world in terms of tuna harvest[1]. For example, it started from about 294,961 tons in 1975, then reached its peak at 371,103 tons in 1985. Although the harvest declined since 1985, it bounced back for the recent years and reached 343,611 tons...
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 structure of wholesale and retail marketing catfish (Clarias gariepinus) were analysed in order to assess the degree of competition and understand the organization of the farm raised catfish (Clarias gariepinus) market in southwestern Nigeria, a major aquaculture fish producing area in Nigeria. The market was evaluated by considering the...
After half a century of fisheries development focused on large-scale fisheries the policy arena is finally becoming more conductive to sustaining small-scale fisheries (SSF) in economically developing countries, with a particular focus on international trade opportunities. Debates for and against increased integration of SSF into globalized trade have been presented,...
The potential for achieving sustainable and efficient harvesting of three species of migratory tuna in the
Western and Central Pacific Ocean is examined. The stocks reside in exclusive economic zones (mainly those of Pacific island countries) and in the high seas. Most harvesting is carried out by distant water fishing...
Fishery scientists distinguish between recruitment overfishing (i.e. suboptimally low reproduction because the spawning stock is fished down) and growth overfishing (i.e. catching fish at an inefficiently young age). We use an age-structured bio-economic model to study how important the (endogenous) recruitment is compared to the growth of individual fish under...
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...
Seafood consumption has been traditionally very important in Spain (about 36.5 kg per capita
consumed in 2003). Hake (merluza) is the main fish species consumed in quantity and value
terms in Spain. But commercialised as hake can be found several fish species and presentations.
When many papers focus on product...
The Southeast U.S. shrimp harvesting sector is one component of the shrimp industry that has generally been unable to make the adjustments needed in response to the growing import base and the resulting supression in prices. Not unexpectedly, therefore, requests for relief from the perceived problems associated with increasing imports...
This document provides an overview of a presentation held during the Industry and Policy Day at the IIFET 2016 Scotland conference in July 2016. The presentation was part of Session A2: Market Implications and Possible Solutions: Certification, Ethics and Social Responsibility. The session was chaired by Maarten Mens, and the...
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...
The French Norway lobster (Nephrops norvegicus) fishery situated in the Biscay Bay is composed by about 250 costal trawlers. These boats are registered in harbours located in South Brittany (Le Guilvinec, Lorient, Concarneau) and in the Vendée (Sables d'Olonnes, La Cotinière). The main particularity of the fishery is that lobsters...
The paper examines the competitive situation between different fleet sectors and their expected development in Senegal and Cape Verde. Recent statistics point towards overfishing, but the situation is not the same for all: Eg. there is a steady decline of Cape Verde artisanal catches, as opposed to a rise in...
As compared to other countries, France has been involved very lately in the discussion about fisheries ecolabelling. Reluctant to adopt the existing ecolabels, the professional organisations, the Ministry of
food, agriculture and fisheries and the European Commission itself tend to create their own label guidelines to take into consideration other...
In 1996 the 1 billion US dollar Norwegian salmon industry was accused for dumping and for having received subsidies in the infant phase of the industry build-up. The accusations were initiated by the Scottish and Irish salmon industry, which regard the Norwegian suppliers as aggressive competitors in their home market....
For many years, researchers have used the theory of planned behaviour (TPB) in order to suggest that human behaviour is greatly influenced by people’s preferences and attitudes, social norms, perceived behavioural control and intentions to act (Ajzen, 1991; Armitage and Conner, 2001) [1], [2]. Over the last 20 years, this...
The role of Women and their rights in Fisheries and Aquaculture Development in Africa. Generally speaking, the word "Gender" refers to the socially constructed roles and status of women and men, girls and boys, behaviors, activities, and attributes that a given society considers appropriate for men and women. Thus, In...
Fresh fish trade in Kribi, Cameroon is characterized by high uncertainty in a context of specific assets. Facing this uncertainty, actors have developed hybrid coordination mechanisms centered on contractual arrangements and networks. These implicit contractual arrangements involve price negotiation, delivery agreements between fishermen and buyers, as well as transactions including...
The paper develops a model of recreational fisher behaviour in which
fishers maximize their individual utility by adjusting fishing time, trips,
catch and size of fish caught. It investigates the optimal behaviour or an
individual fisher with and without constraints such as bag limits. The
model is used to assess...
The paper will focus on the Northern Adriatic Smoot clams (Callista chione) fishery, called in Italy "fasolari". The Italian production of "fasolari" takes place mainly in Friuli and Veneto regions, located in the Northern Adriatic area. Here the system (based on a co-management approach) is a very good example of...
The northwest coast of Mexico is accountable for almost 70 % of the
country´s fishery production. This region, which includes the Gulf of
California and the Pacific coast of the Baja California Peninsula, is also
extremely important in terms of biodiversity and the presence of endemic
species. Consequently, eleven marine...
These three case studies of local fishery policy in Japan examine common causes of a successful fishery policy. This study tries to seek answer on "How did successful cases on Japanese local fishery policy succeed?" To find answer to this question, this study analyzed the relationship and the role of...
Based on fieldwork on the occupational choice and the incomes of fishermen at Chilika lagoon, India, we built an overlapping generations model of a small open economy with access to a renewable common pool resource to show how the share of the workforce in the resource sector, the average income...
The world aquaculture industry is expanding its output but at the same time it is generating concerns about environmental sustainability. It is often heavily concentrated in coastal areas where there is strong competition for space and water resources and where it has been associated with externalities such as habitat destruction...
The nations of the world confront complex challenges in managing fisheries resources in the 21st century. While attention focuses on the need for new institutional ideas, designing and implementing effect governance may be imperiled by inadequate investment in the human capital needed to lead, innovate, and manage. Economics, which integrates...
Sierra Leone is blessed with suitable freshwater resources where freshwater and brackish-water fish species can be cultured. It shoreline is approximately 560km long with an estimated 4, 837.8km2 of wetlands and some 500,000ha of mangrove swamps that fringe the coastline. However, not much of these available natural resources has been...
Africa has traditionally depended on capture fisheries for most of its fish and fish products. However,
with capture fisheries dwindling and human population increasing, alternative sources have become
necessary. Although practiced for many decades, East African fish farming has been funded by donors
whose main interest has been on subsistence...
This paper is designed to “set the stage” for the Special Session on Game Theory and Fisheries. It traces the origins of the application of game theory to fisheries economics, noting that, for the first quarter of a century after the publication of H. Scott Gordon’s 1954 seminal article, the...

We investigate the effects of incorporating a fixed input on equilibrium profits and biomass. We first set up a theoretical model with an input that is fixed in the short-run (vessel size) but that can be used with a variable input at suboptimal capacity. We use this model to get predictions for...
For small island developing states in particular, the fisheries sector plays a critical socio-economic role. It is commonly accepted that the marine resources available to island states can, if properly utilised,
significantly contribute to the sustainable development of the region. It has been further argued that it is the specific...
The two main pillars of the Icelandic fishing industry are the large vertically integrated fishing companies and the SMEs, specialised in fishing, producing or marketing. In order to understand how they are able to function side by side and at the same time secure a relatively high value added for...
The long-range objective of an aquaculture extension system is to help the rural fish farmers to reduce their desperate state of poverty through augmenting fish production. The study was conducted to understand the present situation of fisheries extension and to make a policy recommendations for the development of fisheries extension...
The fish auction markets have proven important in the development of the Icelandic fish industry from the time of their establishment in Iceland in 1987, evening out short run catch variations, allowing for specialization and contributing to increased value creation in the value chain for fish and fish products. This...
Much of fish consumed by the poor are caught by household members and
traded in local markets. These fish trades are rarely or poorly included in
national statistics, and it is therefore difficult to estimate precisely the real
contribution of fish to food and nutrition security. The WorldFish Center
recently...
These experiences working on regional and national problems for fisheries managers in NMFS have given me a perspective on the role of economics in fisheries management that I am going to share with you today. I would like to stress that this perspective is unique to me and does not...
