Recent articles in the multidisciplinary fisheries literature have been critical
of fisheries economics concepts and literature. For example, a paper by
Bromley (2009) entitled Abdicating Responsibility: The Deceits of
Fisheries Policy: Fisheries 34(6):280-302, provides a critical review of
fisheries economics. I explore the main issues raised in this paper and...
The push for ecosystem based management has opened up not only for including more of the natural
systems when managing fish resources, but also a broader perspective on the human systems, and the
diverse activities in the sea. This is reflected for instance in the EU Maritime Policy where fisheries...
According to international law, straddling fish stocks should be managed
co-operatively through Regional Fisheries Management Organizations
(RFMOs). This paper analyzes the stability and success of these
organizations through a game in partition function form based on the
classical Gordon-Schaefer bio-economic model. Results show that the
larger the number of fishing...
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...
A major problem affecting world fisheries today is overcapacity of which
overfishing is both a cause and a consequence. Subsidies are now widely
perceived as an underlying cause of overcapacity, the negative
environmental, social and economic effects of which can be masked by
increasing support from the government. Subsidies that...
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...
This study investigates the economic impact to fisheries and associated sectors if wild fisheries continue operating to
2030 without considering the effects of climate change. Estimates of climate change impacts in Australian fisheries
and their associated probability distributions were derived from the literature and expert consultations. An Input-
Output model...
Bycatch is repeatedly noted as a primary problem of fisheries management
and as the foremost negative impact of commercial fishing. In the Bering
Sea pollock fishery, salmon bycatch reduction measures have included gear
modifications but have principally consisted of area closures. Bycatch
levels of chum and Chinook salmon have risen...
A new type of fisheries management approach termed catch share is set to
be implemented in the US Northeast groundfish fisheries in May 2010.
This approach gives a group of harvesters, called a sector, a portion of the
TAC to manage independently - a hybrid of co-management and individual
quota....
Capacity reduction programs in the form of buybacks or decommissioning programs have had relatively widespread application in fisheries in the US, Europe and Australia. A common criticism of such programs is that they remove the least efficient vessels first, resulting in an increase in average efficiency of the remaining fleet....
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 artificial reef of Vilamoura (ARV) deployed between 1998 and 2001 is situated off the fishing community of Quarteira and the tourism resorts of Vilamoura (Southern Portugal). The reef extends for approximately over 4,000 m long and 1,400 m wide at a depth ranging from 20 to 40 m below...
We examine the realities of selected African fisheries, and assess the extent
to which the existing governance assumptions and management
arrangements are appropriate. Fisheries management in sub-Saharan Africa
is largely derived from a target resource management paradigm, with
interventions largely focussed on limiting fishing effort for single stocks.
We argue...
A comparative multi-fleet rationale of socioeconomic indicators is described aiming a
potential incorporation into fishery management advice at an ecosystem scale. A set of
performance indicators, based on a survey of different industrial fishing fleets in São
Paulo (SE Brazil) which investigated investment, fixed, effort, labour and sailingrelated
costs and...
One of the main obstacles faced by small-scale fisheries in developing country is lack of financial
capabilities. In order to overcome such a constraint, government in developing country often provides
subsidies and small loans in various forms to offset the difficulties in accessing financial markets. Smallscale
fishery in northern coast...
In the past two decades, the French Guyana shrimp fishery has known
dramatic evolutions, largely driven by global changes. On the economic
side, two major driving factors are the globalization of the shrimp market,
with a decreasing trend in real prices, and the long-term increase in fuel
prices worldwide. On...
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...
Aquaculture is an industry regarded as being uniquely placed to reverse
declining supplies from capture fisheries in many developing countries.
There is a growing consensus that this industry offers potential in meeting
key components of Millennium Development Goals (MDGs) around the
globe. While drawing analogue from national statistical data and...
The Chiloe archipelago (Patagonia, Chile) economy lies upon agriculture, fisheries and aquaculture. The marine activities were recently affected by an epidemic crisis in salmon farming and a market crisis for most of the seafood products, including seaweeds. Two Marine Reserves (Putemun and Pullinque) in this island were also badly impacted...
The White paper on European Governance suggests enhanced participation and transparency to improve policies, regulations and outcomes. This paper identifies and addresses difficulties and constraints associated with increasing legitimacy through participation using the Common Fisheries Policy (CFP) as an example. The Green paper leading to the reform of the CFP...
In most of the coastal countries, the fisheries enable to satisfy multiple socio-economic needs such as food safety, public receipts, employment and so on. It is especially true in many coastal developing countries where fisheries constitute a considerable source of food and incomes. However, the strong pressure on the fisheries...
In Senegal, macroeconomic and fishery sector policies stress sustainable
wealth creation for poverty alleviation. However, the current fisheries
management system is incapable of achieving this objective. The most
valuable fish stocks are over-exploited with excessive fishing effort and
capacity and no sustainable resource rents are being produced.
Policy reform has...
Catch share systems are being encouraged and considered in a variety of United States (U.S.) fisheries. Scientists, policy makers, and stakeholders (including fishermen and non-governmental environmental organizations) have different views about potential social and economic impacts and outcomes of these output- oriented systems. Thus identifying and evaluating impacts over time...
The concept of compensatory mitigation is well established as an approach to environmental management. In the past, mitigation programs have been used to conserve wetlands affected by development, and is proposed as a cost-effective approach to offsetting greenhouse gas emissions through reforestation programs. The concept may be equally applicable to...
Indian Ocean Tuna fisheries after a rapid development period from
seventies to the end of the last century are faced with challenges including:
the fishing capacity control, the profitability improvement, and the
limitation of impacts on high seas biodiversity. In this area, tuna species
are exploited by coastal states as...
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,...
The introduction of Individual Transferable Quota (ITQ) fisheries management is controversial as it
typically results in fewer active vessels, fewer vessel jobs, and the remaining vessel crew earning a lower
share of vessel revenues with capital interests, including the new interest "quota ownership", increasing
their revenue share. However, the move...
A survey was conducted to create a comprehensive list of marine protected areas (MPAs) in Japan. There
exist more than 1,000 fishery cooperatives in Japan, and many of them have established no-take zones for
many years. Such zones are usually not reported to the government and, therefore, the complete picture...
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....
The international council for the exploration of the seas (ICES) publish
annual reports on fish stock assessments. Based on the stock assessment
data for the North-East Arctic cod we estimate the effective fishing
mortality, establishing coefficients for the catchability-at-age and the
annual fishing effort. The fishing effort estimates are then...
Worldwide, the scientific community and international organisations have
gradually agreed on the need for an ecosystem-based approach to fishery
management. However, the practical implementation of such an approach
faces huge problems, especially in developing countries where current
fishery management systems are generally weak.
One way to improve a fishery management...
Eco-labelling is considered with increased interest within the scope of fisheries crisis, as a way
to tackle both marine biodiversity conservation and development issues. Along West African
Coast, diversity and specificity of seafood issued from localised fishery systems (or fishery
territories) are remarkable and recognised from long time. Recently, initiatives...
Two of the main problems in fisheries management are over-fishing and
over-capacity driven by the production externality inherent in common
property resource use. Quotas have been introduced to cap total catches,
and regulations such as input restrictions and limited entry have been used
to reduce the capacity problem. Economists generally...
Prior to the introduction of the modern management regime, the concept of capacity constituted no other reference than the technical capacity of a given fishing vessel. However, after closing the commons and the introduction of a an heavily institutionalized management regime, the fisheries sector have been transfomed to complex web...
Amendment 1 to the Golden Tilefish Fishery Management Plan (FMP),
which implemented the most recent catch share program in the Northeast
United States, became effective on November 1, 2009. It replaced a
program that allocated a fixed percentage of annual quota to three groups
of vessel owners with a program...
This paper is aimed at studying the relationship between marine environmental conditions and purse seine anchovy fishery of Alboran Sea through a stock-recruitment model using an historical data set of anchovy fishery in the Northern Alboran Sea that covers two decades from 1985 to 2005 and the HadISST and Era...
In this paper we develop a bidding model for fishermen participating in a
sequential permit buyback auction. A key feature of the model is a
Bayesian updating process, which allows bidders to use information gained
from past participation in future bid selection decisions. Our auction model
was based on the...
The official catch records generally are carried out in the landing operations. There three categories of fishing that are not included in landings; illegal, unreported and unregulated catch (IUU) and are considered like lack of information. It is necessary, to consider these categories of fishing to know the true impact...
The demersal fishery of southern Chile is a complex system including multiple species, fishing fleets and markets. Fishing activity is conducted under a rights-based system for southern hake (Merluccius australis) and hoki (Macroronus magellanicus), where a TAC is allocated in an even manner among fleets and operators. New management approaches...
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...
Lobster (Homarus americanus) ranks first in Canada’s fisheries, but Quebec lobster represents only 6% of eastern Canada landings. During the peak of the fishing season in Quebec as elsewhere, supply is at its maximum and price is the lowest. For this reason, there has been considerable interest in Quebec in...
This paper presents the findings of an 18 months global review of organisations providing sustainable fisheries information to consumers and other channel intermediaries completed in December 2009*. The project was managed by a consortium of nine organisations involved with seafood, the Fish Sustainability Information Group (FSIG), from around the world...
Throughout the Indo-Pacific region, communities are increasingly
empowered with the ability and responsibility of working with national
governments to make decisions about their marine resources. In some
instances, co-management arrangements have been successful at
conserving marine resources by developing locally appropriate rules to
limit overexploitation. These examples have often prompted...
Red tides are algal blooms that have caused significant ecological and
economic damage in Florida. Different nations and regions have addressed
harmful algal blooms such as red tides a variety of ways including distinct
strategies designed to prevent, control and or mitigate the negative effects
of a bloom. While a...
The “product” travel cost model (PTC) improves supply and substitution specification in travel cost
models (TCM), eliminating common biases in estimating welfare effects of qualitative changes at specific
sites. Angling sites and participation are modeled as a system of product supplies and demands; changes
in angling quality at specific sites...
This paper analyzes the effects of spatial closures on the multi-species
groundfish trawl fishery in northern and central California. The analysis
differentiates between changes in total effort and in the spatial distribution
of effort before and after implementation of the closures. We use logbook
data on the location and duration...
In discussing property rights, efficiency and fisheries management economic literature often refers to a fishery with a hypothetical single owner, comparing it to fisheries with more fragmented ownership. Through a range of effort reductions, since the near collapse of the fishery in the early 1980s, the Exmouth Gulf Prawn fishery...
There is an increasing demand for marine space from many different economic sectors in the German coastal and exclusive economic zone: sand and gravel removal, wind farms, fisheries, shipping or oil and gas exploration. Additionally, the Natura 2000 directive requires the declaration of areas for nature con-servation. Opposite to other...
Reefs and lagoons ecosystems of French Polynesia have been since a very
long time the support of important traditional activities. They are today
concerned by conservation public policies, which have considerable
consequences about the relations between local societies and their
environment.
The necessity to stop the degradation of marine biodiversity...
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...
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...
This paper aims to generate insights on the organizational forms within
seafood supply chain and how they can influence the fishing industrys
flexibility and performance. To accomplish this objective, the vertical
organizational structure and strategies developed along the supply chain of
the fishing industry of Yucatan are analyzed as a...
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 Peruvian anchoveta fishery (the largest mono-specific fleet worldwide)
supplies mostly a chain of fishmeal and fish oil aimed at producing animal
feeds, mostly in other continents, whereas others supply chains for direct
human consumption only use <1% of the anchoveta landing. Although
improving during the last 10 years, this...
This study represents an attempt to estimate the effects of SPS measures in terms of trade elasticity of regulations
and competitiveness of exports. In spite of the generalized acknowledgment of growing liberalization of trade
between countries, there are still numerous obstacles to trade, more of the non-tariff type. This study...
This study applies the single-stage modelling stochastic frontier approach to assess the performance of fish farms in Ghana. It examines technical efficiency and its determinants of 150 farms surveyed in 2007 and extend the scope of the analysis to explore interactive effects of farm specific variables on efficiency of production....
The purpose of this study is to apply the extensive framework of theory of planned behavior (TPB) to explain repurchase intention towards fish of Vietnamese families. Specifically, we seek to understand the role of past behavior and habit in explaining repurchase intention besides satisfaction, social norm, and perceived behavioral control...
Methodological difficulties, particularly when multifleet-multispecies fisheries are active, explain pro parte a weak research effort on the socio-economic impact of fishery activities after the implementation of a marine protected area. Two components of the socio-economic impact have been prioritized: the fishing unit profitability and the fishery household income distribution by...
Management actions considered by regional fishery management councils
can generate significant impacts on the magnitude and distribution of the
economic and sociocultural well-being of stakeholders. It is therefore
important that policy analysts be able to account for the relevant parties
whose economic well-being is affected by fisheries and derive estimates...
Many commercial fisheries around the world experience spatial
coexistence of species and imperfectly selective harvesting gears. This
makes these fisheries multi-product industries, that often harvest multispecies
or have a bycatch of another (maybe also valuable) species, which
may or may not be target species for another fishery. Traditional game
theoretic...
On the rural Northwest coast of New Caledonia, the settlement of a world
class mining complex has initiated rapid socio-economic changes, linked
with a considerable demographic increase (+ 65% between 2007 and 2015)
and plentiful job opportunities. In 2007 and 2009, studies on fisheries and
commercialization of reef finfish and...
The Philippines, located within the Coral Triangle which represents the epicenter of marine life abundance and diversity, is the source of groupers traded in Hongkong, China, Singapore and other countries. Grouper production in the country (19.7 th mt), gross value (USD 5.8 mil) and trade value (USD 14.4 mil) is...
In 1995 North Sea herring was estimated to have declined from previous high of around 1.5 million to 400,000 tonnes, the point at which significant reduction in recruitment had previously been observed. The response to this was to cut the fishery by reducing the human consumption TAC by 50% and...
Summer flounder is an important commercial and recreational species in
the Mid and North Atlantic regions of the United States. The stock has
been undergoing rebuilding since 1993 and is not currently overfished but
is not yet recovered. Within this fishery, commercial and recreational
quotas are often exceeded. Current allocation...
In ecosystem-based fishery management, the ecosystem comprises the
natural sub-system and also human components, including user groups,
institutions and the processes of management. Regional Fishery
Management Organizations (RFMOs), particularly those designed to
manage tunas, were not established with an ecosystem view of the pelagic
environment. However, tuna RFMOs have evolved...
The effects of exchange rates and risk on U.S. codfish imports from Canada, China, Norway and Iceland are
examined in the context of the Armington framework. The exchange rate volatility is measured by the generalized
autoregressive conditional heteroskedasticity (GARCH) method. The nonstationarities of time-series data are
explicitly taken into account...
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...
In renewable resource industries, labor is commonly paid with a share of
the harvested resource rather than with a per unit-of-effort wage. Share
cropping in agriculture is one well-known example and entitlement of the
crew to a share of the revenue from the sale of the catch is almost universal...
With a value of NZ$ 85 million the seasonal squid fishery represents one of
New Zealands main export earners. The majority of catch is taken by trawl
from the Auckland Islands, 350 km south of New Zealand, which coincides
with the main breeding and foraging range of the rare Hookers...
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...
Pattern-oriented modeling (POM) strategy has been successfully applied to
build, calibrate and validate agent-based models (ABM) in ecology. Instead
of the traditonal modeling strategy that often requires comparison of the
magnitude of model outputs to a selected set of observed responses, POM
focuses on the ability of the model to...
The Untied States has embarked on a policy path of promoting catch share
programs to manage fisheries. These can include a range of programs, from
community based management arrangements to individual transferable
quota programs (ITQ's). The Mid-Atlantic Surfclam and Ocean Quahog
Fishery has the longest running U.S. ITQ program, which...
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 role of aquaculture industry is becoming more prominent in order to supplement marine capture in meeting the food need of the growing population. In an attempt to minimize depletion of marine fisheries only traditional vessels are allowed to fish along the coastal area while bigger vessels are regulated to...
Although smallholder pond aquaculture in Malawi has significant potential to offset the current fish supply deficit of 27000 tons/year, its production is low (800 tons/year. The major constraints for aquaculture production are: lack of fast growing species; poor access to formulated feed; poor knowledge on modern fish farming practices, and...
"Fish consumption twice per week" recommendation has been adopted in many countries, including Iran, by Nutrition experts. Data derived from food balance sheets (FBSs) and national household food consumption surveys (NHFCSs) show that fish consumption has been increased in the last 20 years in Iran. The gap between supply and...
This study uses hedonic price approach to investigate how price of mussel is formed. The model uses 8896 observations (transactions) from auction market in Yeserke, the Netherland. The results show that product attributes such as meat content, size of the mussel, time and location of harvest are important information determining...
Thousands of small man-made water reservoirs (water bodies with water surface
from five to some hundreds ha) have been developed in mountainous regions for water
supplying or hydroelectricity purpose, these areas are usually residence of poor,
backward minority groups which often lacks of food supplying resources. Development of
fisheries (both...
The study aimed to assess the contribution of seaweed farming based on sustainable
livelihood framework using an indicator system formulated at the FAO Experts Workshop on Methods and Indicators held at Nha Trang University in Vietnam last November 2008.
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...
The aim of this work is to estimate the supply elasticity of the fish regarding the variationsin one of the
most important running costs (fuel cost) for the Galician fleet in the Celtic Sea. The Spanish fleet involved
in the Celtic Sea fishing grounds, also known as the _300 fleet_,...
In recent years, there has been a growing interest of promoting and
rewarding the sustainable management in fisheries and aquaculture using
product differentiation through eco-labelling and organic labeling
respectively. At the same time food safety concerns arise due to the often
food crisis experienced worldwide in the past few years....
With the publication of the NOAA Draft Policy on Catch Shares, which
encourages US Management Councils to adopt Catch Share Programs (yet
another new name for LAPs, ITQs, or IFQs) there will likely be more
deliberations on such programs. With changes mandated in the revised
Magnuson-Stevens Act and the suggestions...
The result of investigation about impact of aquaculture to water environment quality on Nha Phu lagoon (Khanh Hoa province) acknowledged: water environment quality was serious decline because of chemicals no using true, organic waste from shrimp pond, waste water, mud from shrimp pond and agriculture actions, accumulation sediment from mytilus...
In this paper the emphasis is put on an important aspect of renewable resource use that was disregarded until now. It is the evolution of environmental carrying capacity which is traditionally interpreted as a maximal population level that can be supported by the environment (or by habitats of which it...
The deep sea fisheries in Sri Lanka have been in existence since the late 1980s. After 2000 a significant
growth has been experienced in the industry. This has mostly been due to the rapid increase of new
vessels with modern technology and the development of export market opportunities. The Sri...
DOGMATIS is a research project funded by the French Research Agency (ANR, programme ANR-OGM 2007-2010). The transgenic technologies have been applied to fish since more than 20 years now and some strains are at the premarket or market stage in countries outside Europe. In Europe the main risk is a...
