We present the results of integrating the fisheries sector into an existing computable partial-equilibrium global model of agriculture, livestock, bioenergy, forestry, and land use. The model is constructed by reconciling publicly available global datasets from the FAO as well as the literature. The model of the fish sector represents capture...
We present the outlines of an integrated economic-ecological framework
designed to help assess the implementation of the ecosystem-based
management (EBM) of fisheries in New England. We develop the
framework by linking a computable general equilibrium (CGE) model of a
coastal economy to a bottom-up model of a marine food web...
Different methodologies have been used in modeling the epidemiology and economics of aquaculture diseases, including input-output models, benefit-cost analysis, linear programming, simple spreadsheetbased models, compartment models based on differential equations, and spatial models. Despite the advantages that these models provide, there is a need to develop a more integrated approach...
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...
A number of simulations have been carried out to study different management scenarios in the Barents Sea cod fisheries when implementing physical and biological effects of global warming. A regional representation of the IPCC SPRES B2 scenario (world region OECD90) has been obtained through the REMO5.1 model. Water temperatures and...
In 2011 the FAO Committee on Fisheries tasked FAO with the development of an international instrument in the form of guidelines for securing sustainable small-scale fisheries (SSF Guidelines). The SSF Guidelines will facilitate the empowerment and mobilization of stakeholders to promote change towards sustainable small-scale fisheries and hence facilitate the...
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...
In order to ensure sustainable aquaculture development basic elements needs to be taken into consideration, i.e. environmental, social and economic aspects. Most of the research focuses on the environmental aspects and very little of the social and economic aspects. There is no doubt that when dealing with sector development, socio-economic...
This paper fills an important gap towards ensuring gender responsive fish value chains by analyzing the factors that influence women’s participation in fish value chains and value chain governance in Malawi. The study was based on the hypothesis that gendered differences are prevalent in the fish value chains and their...
The Cuban seafood industry has long been an important supplier of certain high-valued seafood products for the world market. In addition, the industry has historically played an important role in providing seafood products for the domestic markets in Cuba. Assistance from the Soviet Union during the 1960-70s led the development...
Fisheries management is characterised by multiple objectives. However, seldomly do bioeconomic models incorporate more than one or possibly two key objectives, typically profit and employment, into an analysis. There are both practical and technical reasons for this. This study considers the incorporation of eight key objectives into a bioeconomic analysis...
Socio-economic analysis of seafood production is important for the conservation of aquatic ecosystems and the management of fisheries and aquaculture activities. Understanding how the livelihoods of people, dependent on the exploitation of aquatic resources, are affected by various changes is essential for decision making. The two main seafood production sectors,...
There is great concern at present that fish stocks are being depleted by over-fishing. Part of the problem of over-fishing is caused by the common property nature of the fishery resources. In particular, high seas fishery resources, such as highly migratory fish stocks (HMFS) and straddling fish stocks, suffer from...
The government in Taiwan has recently instituted a comprehensive program to give fishermen the incentive to reduce fishing effort voluntarily. In this study, we conducted a survey to investigate fishermen's behavior and used the ANOVA analysis and the Probit model to identify factors that affect fishermen's willingness to accept the...

The paper adopts the double-bootstrap data envelopment analysis developed by Simar and Wilson in 2007 to estimate and explain technical efficiency of white-leg shrimp farming in Ninh Thuan, Vietnam. This procedure not only enables consistent inference within models explaining efficiency scores but also produces confidence intervals for these efficiency scores....
Shellfish farming is the most common and the most established activity of aquaculture in France and in EU15. Such as main suppliers of mussels and oysters, mariculture production makes up the referent market for bivalves molluscs, unlike most other aquatic species for which capture fisheries are prevalent. Moreover, the specificity...
Recently, there has been an increasing interest among researchers on efficiency in fisheries. They have not just been focused on the analysis of the efficiency itself but also for other purposes as measures of capacity utilisation. However, often, efficiency analyses do not offer clear results regarding the sources of the...
Catfish production has experienced a decline in the past two years, and farmers have been blaming international competition, exports, low prices and poor feed conversion ratios as the main causes. We evaluate the usefulness of the Analytic Hierarchy Process (AHP) and the Cost Benefit Analysis (CBA) as instruments for rapid...
This document provides a summary of a Special Session held at the IIFET 2016 Scotland conference in July 2016. The registration number and title of the special session were 5313: Analyzing behavioral responses to regulation – what can be learned for management? The session was organized by Florian K. Diekert,...
Acknowledging that there is stochasticity in the dynamics of a fish stock, one has a situation where the fish stock can collapse even without any fishing pressure. To derive the probability of collapse, we suggest a Monte Carlo approach because it is relatively simple model and can capture complex stock...
The success or failure of aquaculture heavily depends on how effectively to manage aquatic animal
diseases. In order to analyze the economic effects of aquatic animal disease control, the specific factors
and magnitudes of benefits and costs are identified with and without the proposed project for the disease
control. These...
Balancing the goals of economic development and sustaining ecosystem services remains a challenge for policymakers, particularly in the marine environment where ecosystem dynamics and human interactions are both complex and poorly understood. Implementing environmental management policies, such as environmental restoration, is a common response by policymakers where economic and environmental...
Over the past fifteen years, the market for bluefin tuna has evolved in an attempt to further enhance the economic value of bluefin tuna landings. Historically, the US East Coast has been a major supplier of high quality bluefin tuna to Japan, the primary market for sashimi grade tuna. To...

Series of financial crises arose in Taiwan since 1997 Asia financial crises, and it starts happened to the community financial institutions since then. In general, damages and impacts to the community and industry are always far more serious than that caused economy by the bankruptcy of a company. Thus, a...
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...
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...
In the administration of its quota management system (QMS), New Zealand sets a “deemed value” fee that must be paid for any landings in excess of annual catch entitlements (ACE.) The deemed value system is an example of a price-capped cap-and-trade system (Roberts and Spence 1976). This paper argues that...
Fisheries management involves considering several biological, economic and political objectives. They are often contradictory. For this reason, it is almost impossible to reach them simultaneously. Andalusian regional government collaborates with the national government to establish fishing plans for local fisheries. The objectives of these plans verify the aforementioned statement. For...
This paper elaborates the use of distributed Genetic Algorithms (DGA) to study an artificial land rental market. The
study is based on a spatial comparative-static model in which a number of spatially ordered agents (farms) compete in an auction
for renting land. Each agent’s behavior is determined by a genetic...
Ecosystem services (ES) provide a pathway to connect ecosystem processes to human well-being. Ecosystem-based fisheries management can utilize the ecosystem service framework to assess trade-offs of actions such as restoration and gear restrictions, or environmental changes such as ocean acidification and warming, and sea level rise. However, due to a...
This study carried out an appraisal of fresh fish marketing in Ondo-State, Nigeria. It
specifically examined the socio-economic characteristics of fresh fish marketers in the study
area, determined profitability and examined market structure for fresh fish in the study area .A
multi-stage sampling technique was used to select 45 fresh...
The central objective of fishery management is to ensure the sustainability and profitability of the resource base. The
importance of the fish stock's age-structure is increasingly recognized in economics and ecology. Still, current
policies predominately rely on the aggregate biomass. We carefully calibrate a detailed model on the North-East
Arctic...
Apprentice programs offer a method to encourage responsible individual behavior by laying the foundation for successful collective property rights. Apprenticeship has three purposes: to restrict the rate of entry, to affect the quality of the participant, and to create the conditions for collective action for sustainability. Apprenticeship could be an...
It cannot be said that aquaculture has ignored sustainable development (SD), judging by the number of standards, guides and indicators devoted to it, produced mainly under the aegis of international organizations such as FAO, The European Union and some NGOs. However, these continue to be perceived in large measure as...
While aquaculture has provided economic and nutritional benefits to millions, there are concerns that
unconstrained sector expansion and intensification, coupled with its ecological and social impacts, globalization
of markets, and climate change, may have undesirable impacts on the resilience of social-ecological systems. A
significant part of the aquaculture expansion is...
The contribution of aquaculture development to the Vietnamese national economy and to farmers’ incomes has been documented in various government reports as well as working papers produced by development projects. However, the role of aquaculture in the life satisfaction of poor farmers has not been considered rigorously. In particular, it...
Throughout the world the landings of capture fisheries are declining and this is not because the fishing nations are managing their resources better but because of the non-availability of the fish species. The reduction in capture fisheries is a wakeup call for the nations to undertake Aquaculture development.
Though Namibia...
The rapid growth in aquaculture production over the last three decades has been one of the fruits of globalisation, as tropical countries have exploited their comparative advantage in the production of high value crops like penaeid shrimp. However, aquaculture is heavily concentrated in coastal areas and it has generated important...
System approach is increasingly recommended as a logical framework for
expert advising in support of integrated coastal zone management (ICZM).
The System Approach Framework proposed by the SPICOSA project
(Science and policy integration for coastal system assessment) aims at
building integrated models, which seek to represent the ecological,
economic and...
Fishmeal prices have increased sharply since the mid-2005 and the relationship between the prices of animal and vegetable proteins have become weaker, at least temporarily. This can be explained by a relatively constant fishmeal supply, which have varied around 6-7 million metric tons the last two decades, and an increasing...
Aquaculture worldwide has grown rapidly, and while this has brought socio-economic benefits to particular regions there is persistent concern over its environmental impact and sustainability. Within Europe there are quite marked regional variations in the intensity of marine aquaculture, and the fact that this occurs in areas where there is...
Change in climate, harvest stagnation in wild fisheries and overexploitation of popular fish
species, combined with a growing demand for high quality protein and a need to sustain
livelihood and improve food security has compelled aquaculturists to domesticate more fish
species in environments which is not rural as the case...
The experiences on reproductive management of native specie such as Petenia splendida (Tenhuayaca) in the last four years in Tabasco, Mexico has generated enough information to allow the development of a technological package for supporting sustainable rural production, particularly in areas where most of the population belongs to ethnical groups....
Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish
population-dynamics and production, coupled with an aquaculture production model, to investigate
effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying
capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production....
The Aquaculture & Fisheries Collaborative Research Support Program (AquaFish CRSP), headquartered at Oregon State University, brings together resources from US and Host Country institutions to promote sustainable solutions in aquaculture and fisheries. Through integrated, multidisciplinary partnerships, the program aims to increase aquaculture productivity, enhance environmental stewardship, address gender integration, and...
The direct economic values of aquatic resources used in various livelihood activities by
households in selected rural villages of Cambodia were estimated using the net economic value
approach. Data utilized were from 540 aquatic resources dependent households from 3 provinces
gathered using household survey, longitudinal monitoring and participatory rural appraisal...
There is much talk on recycling organic effluents, closing nutrient cycles, maximising energetic efficiency, and maintaining
equilibriums between humans and nature, etc., even for lakes and estuaries. Aquatic systems provide us (humans)
the service of recycling decomposable organics and deliver fish at the same time, notably, as long as the...
Fish farming has grown very rabidly during the past few decades. One component of this expansion is the introduction of new species, previously unknown to most consumers, to world markets. Arctic char, a cold water salmonid, is one of these species. In 1987, the total commercial supply only amounted to...
Although considerable research is required on the impact of global climate
change on fisheries the general expectation is that climate warming in the
Arctic will improve conditions for many fish stocks. Climate warming is
taking place faster in the Arctic than elsewhere on the planet. The reduction
in sea ice...
The result of changes in regulation or monitoring and enforcement of commercial fisheries are highly dependent on fishers’ supply response decisions. One central determinant of fishers’ reactions to such changes is their risk preferences. Empirical studies of fishers’ preferences have found that most fishers are risk averse. In this paper,...
The swordfish fishery is one of Hawaii's most lucrative, and also most highly regulated, fisheries. According to the United Fishing Agency (UFA) fish auction data in 2005, average swordfish (shallow-set)
revenue per trip was $76,897.03 and average tuna (deep-set) revenue per trip was $36,382.14. Swordfish trips, however, comprised of only...
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...
In the past, Java island was known as “Java-dwipa”(a place where over-whelmed with food stock). However, due to over population, then food security became fragile including in fisheries sector. The such situation is worsen by economic and political turbulency in Indonesia.This study aimed to explore the level of fishers’s powerment...
In the framework of the H2020 PrimeFish project, whose general objective is to contribute to enhance the economic competitiveness of European fisheries and aquaculture sectors, the analysis of innovation and new product development in the seafood market is an important issue. Simultaneously, concerns on the environmental impact of seafood industry...
The depletion of important fish stocks and the degradation of marine ecosystems are common problems worldwide. Two approaches that have been widely used to restore depleted fish stocks are the implementation of harvest control rules and the establishment of marine reserve networks. Harvest control rules, underpinned by the monitoring and...
The animal protein intake in Nigeria is grossly insufficient yet the retail price of fish is rising. Market intermediaries, alleged to charge excessive and unjustifiable marketing margins (MM), are often blamed for this. This study examines this allegation using data from 225 sun-dried fish traders classified into three groups. Data...
The contributions of small-scale fisheries to income and employment are well recognized but not sufficiently understood. It is difficult to gauge, for instance, whether this sector is economically viable, especially in the context of large-scale economic, social, political, and ecological change processes. These knowledge deficits create an environment of uncertainty...
This paper highlights the fishing industry's views on economic impact assessments related to fisheries, and in particular the Scottish Government's assessment accompanying the MPA Consultation. The industry felt this assessment was incomplete, failed to recognise the true impacts on fishermen affected and failed to acknowledge local impacts on communities. We...
The main purpose of this study is to answer a question, "Are the Japanese Fisheries Responsible?" The author tries to find the answer by analyzing a historical trend of the Japanese fisheries policies, recent legislation such as "Fisheries Basic Law" and "Sustainable Aquaculture Production Assurance Law", and example cases of...
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...
Vietnam fisheries industry is expanding in scale and increasing its position in the national economy. It supplies not only a basic food commodity, but also the input for other industries, source of nutrition, employment, income, and foreign exchange earnings. The importance of fisheries, hence, emanates from its contribution to the...
Despite the efforts of natural resource economists to implement rights-based fishery management systems, many of the world’s fisheries remain over-exploited and lack an institution to change course. Given the status quo of overharvesting and depleted fish stocks, it seems natural for a harvester co-op to jointly curtail fishing mortality, which...
In many salt-water recreational settings an imprecise measure of site choice is often collected based upon the individual's launch-point. For anglers who continue on from the launch-point in a boat, this imprecise measure of site choice is likely missing important on-water trade-offs thereby affecting the accuracy of recreational benefit measures...
The use of artificial reefs in the creation of commercial and recreational fisheries has received growing attention in recent years, and artificial reef development programs are now being undertaken by a number of countries worldwide. Despite a substantial volume of scientific information on the technical and biological aspects of artificial...
There has been significant growth in the catches of bluefin tuna in the Atlantic Ocean and especially in the
Mediterranean Sea for the last decade due to the expansion of fattening farms which export their production to
Japan. There has been an increase in catches due to strong demand and,...
Artisanal fishermen are the great unknown of fisheries. Being the more
numerous segment, is the more abandoned community by managers. In a
generalized context of overcapacity and taking into account the dwindling
state of resources, the situation seems to be paradoxical since artisanal
métiers are considered to be the less...
The artisanal fishing sector is very active in Senegal, providing 75% of total catch and major contributions to food supply, employment and exports. Artisanal fishing is spread along the coastline and involves different groups of migrants or sedentary fishermen using various fishing gears and techniques. Resources are heavily exploited and...
El Archipielago de Colon, more commonly known as the Galapagos Islands, is a province of Ecuador located about 600 miles off the coast of South America. It consists of approximately 45 volcanic islands (15 major and 30 minor) plus scores of smaller islets and rocks. The total land area is...
Indicators of the economic performance of fishing vessels are frequently computed in many countries. Usually, measures of economic performance are based on the return on capital invested. However, several measures of capital value exist, according to the economic information available. In this paper, we use different types of information to...
In this paper, we examine the sustainability of fisheries system in Yoron Island, Kagoshima Prefecture, Japan using participatory flag modeling approach. The main purpose of flag model is to analyze whether one or more policy alternatives can be classified as acceptable or not in the light of an a priori...
Studies on poverty have focused predominantly on low income and food poverty. Little or no attention has been given to the emerging problem of adequate calorie intake accompanied by low micronutrient levels, particularly in diets of rural households in transition and developing economies. Micronutrient deficiencies are related to child mortality,...
The Maya of Mexico and Central America pursue multiple livelihood approaches, relying primarily on natural resources obtained from the rainforest. Fishing in the many water bodies of the region is one among many livelihood opportunities, but its relative importance has not been assessed previously. Indeed, there remains an overall lack...
There is a marked need to better understand the interconnectivity between poverty alleviation and environmental sustainability since impoverished communities are often dependent upon their natural habitat to meet basic needs, and strategies to improve the livelihoods of the poor must consider the role of their natural environment. While previous studies...
This paper deals with risk and uncertainties that are an inherent part of
designing and implementing fisheries rebuilding plans. Such risk and
uncertainties stem from a variety of sources, biological, economic and/or
political factors, and are influenced by external factors like changing
environmental conditions. The aim of this paper is...
Reducing harvesting capacity in fisheries is of international importance. In 1999, member nations of the United Nations Food and Agricultural Organization (FAO) agreed to an International Plan of Action to reduce fishing capacity. Two initial concerns were the acceptance of a workable definition of capacity and the development of methods...
The paper presents a spreadsheet based benefit-cost framework for assessing the net benefits of domestic
tuna processing to the resource-owning nation. The framework has a number of advantages including
transparency, flexibility, and a check on internal consistency. The case study examines the effects of a
range of tax, access fee...
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...
Shrimp farming in Iran is one of the fast growing segments of the economy. In 1994, around 1%
of Iranian shrimp production was farmed and by 2003 the share of shrimp farming increased to
60%. In spite of the fact that shrimp culture had relatively rapid growth in last decade,...
Capture fisheries can potentially provide a wide range of social benefits, many of which make important contributions to local livelihoods and national economies. However, in practice, and in many representations of fisheries, the starting point for assessment is the biological, fish, element of the system and its production potential. The benefits...
Bycatch of non-targeted species in marine fisheries has become a major policy issue in fisheries management over recent years. One approach to curbing the bycatch problem is the voluntary sharing of detailed spatiotemporal information between vessels as an aide in individual bycatch avoidance as well as a tool to lower...
This paper studies the consequences of creating a marine protected area (MPA) on a recreational non-extractive use of the ecosystem (scuba diving), and draws a parallel with the impact of MPAs on
commercial fishing. The first part of the paper presents some preliminary results of a field survey of scuba...
Though the basic purpose of MPAs is marine ecosystem conservation, the
question of their influence on the local economy is often critical since it
governs their social acceptability. This paper addresses the problem of
measuring the consequences of creating a marine protected area (MPA) on
recreational extractive and non-extractive uses...
Is there a direct link between poverty and illegal fishing in Lake Victoria? The paper argues that presenting poverty as the main driver of illegal fishing in Lake Victoria masks core underlying causes of illegal fishing. Illegal fishing practice is a significant ecological trend in Lake Victoria. It is not...
In Peru, the fisheries are characterized by a strong fishmeal industry. The
species used for fishmeal production is mainly anchovy and also some
other small pelagic species. There is some concern that an excellent source
of food is used for a product not directly going for human consumption.
Since several...
Fishers exploit populations that are heterogeneously distributed in space and time without full knowledge of species distributions and with fishing gear that is not fully selective. The ability to change catch composition is limited by species mix at a particular location and time and the capture characteristics of the fishing...
Coral reef ecosystems provide many important services to society. Their importance is not only proved by their beauty but also because they provide food and livelihood for millions of people in communities around the world, especially in developing countries.
