of fish. The global tuna market is worth in the region of $6billion and
annual catch volumes of around 4 million tonnes. The tuna supply chain is
global and it is broad and complex involving multiple stakeholders....
Many of the coastal counties in Florida have active artificial reef
deployment and monitoring programs. These reef systems have been
shown to be an important destination for the marine recreational boating
industry, as well as for the for-hire commercial sector (i.e., six-pack charter
vessels, guide boats, party/head boats, and dive...
The UN Law of the Sea of 1982 assigned rights and responsibilities to the
fishery resources within 200 nautical miles of the coast (i.e.,the Exclusive
Economic Zones: EEZs) to the adjacent maritime countries. A key
responsibility is the requirement that these countries manage their marine
living resources sustainably through time...

Some export fisheries in Australia have opted for third party certification to gain or maintain access to export markets. For domestic fisheries, the economic and management benefits of third party certification have yet to be fully demonstrated. However, as a response to community perceptions, competition with other users of the...
Economic growth is accompanied with a shift of labor away from the natural resource sector. In developing countries some people have to leave fisheries as a way of making it possible for those who remain in fisheries to share in the productivity gains of the entire economy. Increased investment in...
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...
This paper presents findings from an investigation into the stay or exit decision of vessel owners in Scottish fisheries subject to stock recovery measures. Semi-structured in-depth interviews were conducted with 39 vessel owners during and following a vessel buy-back scheme. Empirical results show key factors affecting the decision to stay...
The Mexican Oyster fishery in the Gulf of Mexico annually produces only
50,000 MT, 95% of Mexico oyster production. Oyster production has
fallen drastically in most coastal lagoons, this decline has been attributed to
factors as overfishing, mismanagement of natural oyster beds,
environmental degradation and lagoons pollution. This work proposes...
An understanding of fishers' decisions to exit or stay in a fishery is important for developing effective policy measures. In this study, we analyze the factors influencing this decision using a large administrative database covering the entire Swedish fisher population, their family ties, and detailed labour market data spanning two...
We investigate how individual preferences affect noncompliance in fisheries. We use data from a combined web-based experiment and survey of Norwegian fishermen to empirically analyze this. In the economic experiment, the participants won real money in a set of lotteries based on their answers and lottery outcomes. Based on the...

In the Pacific Ocean, the total catch of skipjack tuna has been increasing rapidly. Then, eight of Polynesian, Melanesian, and Micronesian countries (PNA countries) have concluded a cooperative management of tuna fisheries. Although those countries do not catch a large amount by themselves, the main migrating area is included in...
If the study of the fisheries dynamics increasingly seeks to take into
account the evolution of fishing fleets, the main mechanisms which govern
their evolution at the local, national or international levels, are often not
studied at all, or only partially studied. This applies in particular to vessel
entry and...
Establishing marine protected areas (MPAs) often results in fishers being
displaced from at least some of their existing grounds. A direct
consequence of this is that governments may be required to make
compensatory payments to the firms that are affected. Experience has
demonstrated that these payments can be significant, as...
In the quest to limit the bycatch of non-target species, marine protected
areas (MPAs) have been frequently utilized. MPAs are popular with
ecologists and fishery managers because of their relative ease of
administration, habitat protection benefits, and the widespread acceptance
of MPAs as an instrument of choice for the ecosystem...
Australia’s western rock lobster fishery is its most valuable and hence from a biological perspective most tightly managed major commercial fishery, yet it has been beset by problems of miniscule recruitment over the past 3 years. This coming year 2010-11 is little better. It was the joint first Marine Stewardship...

The research aimed to apply wellbeing concepts to both better understand fishery...
This paper investigates the welfare effects of random closures in a fishery
operating under open access. At each point in time, a fishery is facing the
probability of an extreme event that impairs fishing activities but has no
direct impact on the fish population. Examples include massive blooms of
dinoflagellates...
In this paper we try to assess the welfare implications of the Tanzanian fisheries boom following from the increase in quantities and prices of the Lake Victoria Nile perch export primarily to Europe over the last twenty years. We have a micro level perspective using data from a 1993 World...
The paper will report on the development of a new set of wealth-based
Fishery Performance Indicators (FPI) for evaluating and comparing the
worlds fisheries management systems. A wealth-based fishery management
system is one that is ecologically sustainable, socially acceptable, and
generates sustainable resource rents or profits. The Fishery Performance
Indicators...
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...
Madagascar is the world, fourth biggest island, and
one of the world‚ poorest countries. Given its severe
poverty, Madagascar has no large-scale domestic fleet. Consequently, it is required by the United Nations
Convention on the Law of the Sea to rent these un-exploited resources to distant water fleets (DWFs)
from...
Fisheries economics has recently earned a seat at the global fisheries governance table, with everything from subsidies, to high seas fisheries, to Indigenous rights, food security, and human rights now being open for global assessment. The papers in which these studies are housed are in high impact journals, are highly...
Recent aggregate models of recreational participation have largely focused
on demand systems and choice models utilizing cross sectional data. While
these strategies may be advantageous for the estimation of welfare
measures, they have left unexplored the relationship between recreation
participation and general temporal economic trends. This research shifts its
focus...
Vulnerability assessments play an important role in the climate change adaptation process in that they link physical changes (either current or projected) with the ability of aquatic and human systems to cope or benefit from such change. In general, a vulnerability assessment helps to target adaptation actions by better understanding...
This article gives insights on the complex balance between coalitions structure,
resource state or dynamics and agents’ heterogeneity to avoid bio-economic
collapses. A model bringing together coalition games and a viability approach
is proposed to focus on the compatibility between bio-economic constraints and
an exploited common stock dynamics. It is...
This paper examines the viability of the management of a transboundary resource, the Bay of Biscay anchovy (Engraulis encrasicolus L.). A deterministic model is used to simulate the anchovy dynamics, with the fish stock consisting of two age groups, “young" and “old", while recruitment follows a Beverton Holt pattern. Two...
The paper presents a vessel level simulation model of the impact of a landing obligation on a typical Scottish demersal trawler under a discard ban in addition to existing quota management controls. The simulation model is based on a simple microeconomic model of firm behaviour and predicts landings, discards and...

The study employs logbook data containing over 64,000 sets, matched with observer data from 2008 to 2015 in an undisclosed...
Japanese foods such as sushi and sashimi are in boom in US markets, and the US import of the Japanese fish is expected to increase. However, the growth rate has not been so rapid as the import of agricultural products such as green tea and soybean paste. At the same...
The notion of individual transferable quotas (ITQs) has permeated the fisheries economics literature over the last 40 years. The most long-standing prediction about ITQs has been extensively documented, namely that transferable property rights to harvest induce changes along the extensive margin via consolidation of quota among a smaller number of...
Over the past several years we have been developing Fishery Performance Indicators (FPIs) to measure the degree of success fisheries systems have in achieving environmental, economic and community outcomes. We have also developed indicators of key input factors. Among the input factors we have explicitly developed indicators for women’s participation and leadership...
The contribution of aquaculture and/or fisheries to Gross Domestic Product (GDP) directly or indirectly are essential indicators for policymakers to assess the sector's economic performance and make informed policies or decisions that can affect the level of political and financial support to the sector, and hence, its development pace. Despite...
Recreational fisheries are severely understudied by fisheries economists, in
spite of their growing importance in the context of fisheries management.
While recreational demand models have been extensively applied to
recreational fisheries, they have rarely been successfully integrated with
bioeconomic models to evaluate policy changes. Furthermore, theoretical
models of open access...
Marine mammals and sea turtles are protected from commercial fishery interactions under the U.S. Marine Mammal Protection Act and Endangered Species Act . By design, enforcing area closures is generally less problematic than gear modifications from an enforcement standpoint. Consequently, non-compliance is a greater issue with gear modification regulations. The...
In June 2015, the UN General Assembly mandated the negotiation of a legally binding instrument on the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction (ABNJ). The proposed ABNJ Implementation Agreement (ABNJ IA) will have implications for the conduct and regulation of high seas fisheries and...
Understanding the complexities of ecosystems is difficult enough, but when the human dimension is added to the inherent uncertainty and risk in fisheries management, the actual versus expected results move from the counter-intuitive to the paradoxical. Without an adequate understanding of the interrelationships between ecosystem components, including the human dimension,...
Implemented in 2011, the West Coast Groundfish Trawl Catch Share Program was designed to achieve multiple economic goals and objectives for a diverse multispecies fishery, including increasing net benefits, profitability, flexibility, and utilization of harvest allocations. Here, we leverage seven years of comprehensive cost and earnings data to evaluate progress...
As changes in climate and corresponding ocean shifts threaten U.S. fisheries with uncertain change, West Coast marine scientists and fishery management institutions have newly emphasized ecosystem-based analysis and management. The development of the West Coast-specific California Current Integrated Ecosystem Assessment (CCIEA) has accordingly allowed for economic analyses and the social...
U.S. imported 2.3 million metric tons of smoked herring in 2007 costing $707,000. Hence it is important to investigate factors influencing the importation of smoked herring into the US. We used time series data from 1976 to 2007 to estimate an import demand function: log(Mt) = a0 + a1*log(Pt) +...
The present study uses normalized profit function and adaptive expectation approaches to analyze U.S. catfish farm supply. Empirical estimations give short-run supply elasticity of 0.25 and 0.26 and long-run supply elasticity of 0.47 and 2.1 in each of the two approaches, respectively. Technological improvement is attributed for only 9.8% out...
Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
The objective of this research is twofold. First, this study uses a
cointegration model to investigate possible potential long-run pricing
relationships among the major landings of the Hawaii tuna longline fishery
(bigeye, yellowfin, skipjack, and albacore tuna). This analysis will
determine to what extent changes in the price of one...
Farmed fish products in Europe are mainly addressed to the market of live and fresh whole fishes. Only for the trout sector, due to their vertical integration, is it common to process/transform the fish, offering a wider range of products to final consumers. One key factor that makes the supply...
Catch share programs are emerging as a rights-based management tool capable of improving biological and economic performance in marine fisheries relative to traditional command and control regulation approaches. This paper examines the determinants of the transition from command and control regulation to rights-based management in marine fisheries. I develop a...
Transition of fish farming from subsistence to sustainable semi commercial activity in Uganda Fish farming in Uganda has not been taken to semi commercial levels by small scale famers due to many challenges.

Emergence of fish farming in Brazil has generated significant effects on household agriculture, in terms of food security and income generation. However, small-scale fish farmers in the state of Tocantins have been affected by a transformation process concerning the emergence of supermarkets in the fish market. The lower prices and...
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...
The introduction of private property rights in common pool resource systems is not occurring at random, but depends on various factors, including the state of the resource itself. This inherent endogeneity problem of policy implementation makes it difficult to make any causal inference between the regulatory regime and the state...
In the globalizing era, world trade of fishery resources has sharply
increased. Because capture fisheries are hard to be managed, growing
opportunity for fishery trade may cause the overexploitation of world
fishery resources. For instance, the theoretical model developed by
Takarada et al (2009, mimeograph) implies that fish stocks may...
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...
India’s seafood export surged new heights and continued unabated amidst global recession. The exports surpassed 2.85 billion dollars with dynamic geographic and commodity diversifications. Indian economy grew consistently post liberalization with higher purchasing power and consistent demand for food products. The consumption behavior skewed towards protein food with increased fish...
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...
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...
Within Indonesia and across the region the requirement for traceability within the seafood supply chain is limited to meeting the basic standard of HACCP, namely that the individual fish be traceable back to the 1st supplier, for quality sampling purposes. No common template for traceability exists and hence companies follow...
Fisheries and agriculture form the backbone of the Solomon Islands economy. The population is around half a million people, of whom 94 percent live within five kilometers of the coast. Women are key to effective fisheries management and development in Solomon Islands. They make up half of the community for...
Women are crucial to the fisheries and the aquaculture sector. Worldwide, fishery and aquaculture production activities provide revenues to an estimated 155 million people, of whom a substantial proportion is female. In developing countries most fishing activities fall into the small-scale fisheries sector employing roughly 40 million people, and directly...
The paper argues that Cost-Effectiveness Analysis (CEA) can be a suitable
evaluation tool in cases where some of the benefits are difficult to measure
(e.g. habitat protection) and where the tangible benefits are lower than the
cost. An example is polities aiming at protecting a single species in
multispecies fisheries....
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...
Considerable attention has been applied to the development of models explaining how fish stocks change over space
and time, from relatively simple stock-recruitment relationships to ecosystem models with a complex food web
structure. However, in many case studies fishing effort is assumed to be exogenous and even in dynamic models...
The hilsa shad (Tenualosa ilisha) fishery is the largest single species fishery of Bangladesh managed under open access system was chosen for the study. The purpose of the study was to develop optimal policy to assess the optimal exploitation of the fishery. The objective was to maximize the net benefit...
A major simplification in bioeconomic models is that the model parameters
and functional forms are assumed known. In fisheries, the failure to capture
model uncertainty can easily cause overconfidence in model outputs and
resultant policy recommendations. Although fisheries modelers regularly
assume rather complete knowledge of the systems they study, in...
This paper illustrates a case study to identify problems and actions to build the basis for an integrated fishery management plan, considering stakeholders participation. The application was made on the southern complex multispecies groundfish fishery, where operate various scales of production under a right-based fishing system. A multimethological approach (Mingers,...
Women's contributions to fisheries are often overlooked in fisheries management, economic analyses, and consequently, in policy decisions. Fortunately, women's contributions are gaining recognition despite a lack of quantitative data describing the scope and scale of their participation in the sector. While there are numerous studies describing the role of women...
In developing countries the framework for institutional engagement in small-scale fishing communities needs to consider the regional, social, economic and environmental complexities of informal resource-based economies. The combination of socio-economic trajectory of artisanal fisherfolks, their relationship with the environment, the economic pressures and the public policy framework, which often regarded...
Tuna and other highly migratory and trans-boundary fish species form an important seasonal component of the annual catch taken by thousands of small-scale inshore and coastal fishers in the Bay of Bengal region of the Indian Ocean. However, there are serious concerns about the productivity and sustainability of the fisheries...
In order to survive and prosper fishing companies have to balance the need for continuity and change. Investment strategy is a good indicator on the direction companies are headed in terms of capacity, onboard production, and the financial risks they are willing to take. However, the success of an investment...
Ideally, we seek to develop perfectly integrated ecological-economic models, drawing on the best data, modeling and knowledge of each of the disciplines, into one coherent model to inform policy. The realities of achieving such are thwarted by data and model compatibility issues. For example, ecological data may be available on...
İstanbul Bosphorus is a strategic fishing area with its physico-chemical and geographical characteristics. Also because of İstanbul metropole is taking part there, İstanbul aquatic Products fish market has become an important position in the region. The high variety of species and product entrance quantity rates provided us a continuous data...
Fisheries economics theory suggests that weak fishery management
institutions, such as an open access regime, provide the motivation for
fishers to act as if they have infinite discount rates. This theory has serious
implications for the management of small-scale reef based fisheries in
developing countries, many of which are open...
In the North East Atlantic there are several straddling stocks, including herring, mackerel, and blue whiting, which are exploited both within coastal states' 200 nautical mile Exclusive Economic Zones (EEZ) and on the high seas. The pelagic fisheries of the North East Atlantic are all harvested by the same six...
Regulating fishing trough overall catch limits, sometimes referred to as olympic fishing, has been heavily criticized by fisheries economists for its unhealthy incentives for overcapacity, excessive costs, quantity focus and uneven supply patterns. In spite of this the Icelandic government opened an olympic style coastal fishery for small scale vessels...
