The aquaculture sector is uniquely placed to complement production from the stagnating capture fisheries sector and it has advantages in terms of controllable production characteristics. However, aquaculture poses undeniable economic, environmental and social challenges that may be poorly evaluated or inadequately addressed within current policy frameworks. In such cases, the...
Environmental resource values are often obtainable only through stated
preference or hypothetical surveys because other nonmarket valuation
methods only account for part of the resource value or are unsuitable.
Despite the recent popularity and many advances in discrete choice
techniques for nonmarket valuation, the implications of questionnaire
structure, namely framing...
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...
Tuna farming industry of Japan has achieved complete culture and currently tries to seize the opportunity to materialize the industrial mass production of the artificial seed. Japan was only 3,000 tons (8%) among 37,000 tons of 2007, which was the peak of world production of cultured tuna. However in 2008,...
Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management
indicators tied to outcomes described in management plans or on the achievement of a single objective such as an
increase in the size or number of older, more fecund female fish in a protected...
Although diversification of producing activities and migration abilities are often supposed to reduce vulnerabilities of the rural households, it should not be considered as a general rule. In the Central Delta of the Niger River in Mali, fishers are massively involved in rice farming as secondary activity and many of...
The paper reviews the management and bioeconomic modeling of the Southern Bluefin Tuna
stock. It describes two studies using simultaneous, non-cooperative, three player games to predict
revenue and stock outcomes generated by a deterministic, discrete, age-structured model of the
SBT population. Two versions of the model, corresponding to biological and...
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...
Since 1999, the scallop fisheries have been granted access to closed areas on Georges Bank, and the
access programs have been managed through individual vessel quotas for scallops, and a common-pool
total allowable catch (TAC) for yellowtail flounder bycatch. The scallop resource is neither overfished
and nor is overfishing occurring,...
The north coast of Java Sea is home to thousands of small-scale fishers fishing for small pelagic fish. The
small pelagic fisheries have been the main economic and social activities for coastal communities where
other alternatives are limited. The fisheries have been experiencing turbulent states during the last thirty
years...
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...
Problems with the security of imported foods and with false indications of origin have recently
been uncovered in Japan, leading to increased consumer interest in the country or place of

DOGMATIS is a multidisciplinary 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...
Due to the development, Japan lost more than half of seaweed beds
because of reclamations, water brake constructions and water pollution
after the WWII. As a result, coastal fisheries production decreased from 2
million metric tons to 1.5 million metric tons. Building a forest in the sea
has been paid...
Nile tilapia has been cultivated in intensive systems in Yucatan, Mexico, during the first years of this century. Nevertheless, its adoption faces technical (related to the use of commercial feed) and marketing problems (fixed price of $2.14/Kg), which are analyzed in this paper. To do this, a bioeconomic model of...
With a national policy on catch shares in progress in the United States and
increasing use of transferable fishing rights in fisheries worldwide, it is
important to understand how the markets created by these programs
function in the real world. This paper presents information collected from
interviews with Florida spiny...
In this paper, we analyze the efficiency of the existing management regime
of the Bay of Biscay anchovy fishery, which has been closed since 2005
due to stock collapse. We also study Pareto improving strategies to
improve management of the fishery once the moratorium is lifted, expected
for spring 2011....
The result of investigation about aquatic exploitation actions on Nha Phu lagoon (Khanh Hoa province) acknowledged: Exploitation of fisherman was individual (100%) and professional skill was very low. Professional exploitations were major drag net (36.92%), drift net (20 %), tunny net (16.92%). They exploited in Nha Phu lagoon and exploitation...

New Zealands quota management system is based on transferable
harvesting rights operating within regulated allowable harvest limits. The
system has evolved since its implementation in 1986. One particular
challenge has been the design of mechanisms to encourage the balancing of
catch against quota. A model is developed for a target...
Fisheries constitute a major productive sector in Latin America and the Caribbean. This sector generates income, provides employment, and makes a significant contribution to food security and the generation of foreign exchange. With most fishery resources fully exploited or depleted, opportunities for fishery development lie primarily in restoring depleted
stocks...
An international symposium devoted to Research and small-scale fisheries (Durand, Lemoalle, Weber,
1991) in Montpellier (France) in 1989 came from increasing evidence that “the complexity of small scale
fisheries calls for applying knowledge from many fields in combined studies that can take advantage of a
whole range of information”. Has...
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...
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...
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...
Recreational fishermen quickly adjust fishing effort directed at a specific
site to variations in fishing quality. Holding all other quality parameters
constant, the functional relationship between fish abundance and the
resulting recreational fishing effort is denoted an effort response function.
This paper proposes a Cobb-Douglas utility function for the benefits...
The herring stocks in the Northeast Atlantic were nearly fished to
extinction in the 1970s. This collapse is usually attributed to advances in
fishing technology. The impact of productivity shocks depends critically on
how sensitive the fish catch is to the size of the stock. If the catch per unit...
40 years ago the Atlanto-Scandian herring stock collapsed with severe consequences for Iceland´s monotonic economy at that time. Two years ago the international credit crisis brought the country´s largest banks to insolvency, which shocked the whole economy with butterfly effects in neighbouring countries. The paper begins with an overview of...
Management changes in the coral reef fin fish fishery of the Great Barrier
Reef provide a natural experiment of the efficacy of combining no-take
areas and dedicated catch shares. A spatially-explicit bio-economic model
of the fishery is used to analyze the tradeoffs between biomass and the net
returns from fishing...
Modern fisheries management is strongly based on ecosystem theory. Ecosystem management involves direct manipulation of the habitat and population as well as human activity in order to optimize sustainable returns to humans. The ecosystems approach is widely viewed as a new concept in management of fisheries and aquaculture. Ecosystems based...
The expansion of the aquaculture sector over the last two decades has coincided with the growth in
importance of supermarkets in fish retailing in the EU. This paper presents a Value Chain analysis of

In 1996, the US New England Fishery Management Council formed a
technical team (PDT) to develop a new plan for Atlantic Herring (Clupea
harengus harengus). The inshore stock was close to fully exploited while
the offshore stock was underexploited. There were few full-time herring
harvesters and very few processors. Fresh...
Management strategy evaluation (MSE) is a methodology which allows to compare the efficiency of different management strategies in order to ensure the sustainability, in particular those based on viable control theory.

We compare the productivity of technology adopters to non-adopters using
a cross-sectional survey of artisanal gillnet vessels on the east coast of
Peninsular Malaysia. Technologies include cell phones, GPS, sonar, and
mechanical winches for hauling nets. Stochastic frontier analysis is used to
measure differences in production frontiers and technical efficiency...
The New England Multispecies (groundfish) fishery is about to implement
the catch share management system, where self-identified groups of
harvesters called sectors receive quota allocations of total allowable catch
(TAC) proportional to the harvest history of their members. Joining a
sector is voluntary, thus there will be both sector members...
A Seafood Environmental Management Systems manual (SEMS) has been developed by Bord Iascaigh
Mhara (The Irish Sea Fisheries Board) in conjunction with the Irish fishing industry to encourage
fishermen to adopt an environmentally conscious, responsible and compliant approach to their business.

The present study employs a cointegration method and error correction model to analyze the long-run relationship and short-run adjustment of aggregated seafood import demand function for selected Caribbean countries. The results show that there exists a long-term equilibrium relationship between Caribbean seafood import and related factors. Import demand elasticity is...
The cumulative global loss of economic potential from fisheries over the
last 30 years is US $3 trillion. More than half of these fishery sector losses
come from developing countries. However, these are only primary costs
and do not take into account human security risks associated with poorly
governed fisheries....
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...
Overcapacity is probably the most fundamental challenge to fisheries management as it can lead to both overfishing and to low profitability. Most of the Norwegian fisheries have limited entry, through the use of annual permits (coastal fleet) and licences (ocean going fleet) in combination with individual vessel quotas (IVQ). Limited...
Concerns about declining stock and profitability in the Tasmanian rock
lobster industry led to the introduction of individual transferable quota
(ITQ) management in 1998. In this study, fisher groups were categorised
by effort and quota ownership traits to examine response to revised
management, and how profit drivers moderated this change....
Since the 1990s, moored Fishing Aggregating Devices (FADs) have had a
sharp success in the Lesser Antilles and beyond, because they make it
possible for small nondecked fishing units to reach, at low costs, offshore
resources which they could do only seasonally or resources normally
accessible by large scale vessels...
The recovery of fish stocks is in principle an investment decision weighing up short term losses against
future gains. In the Common Fisheries Policy (CFP) of the EU long term management or recovery plans
are a main instrument. One of the basic aims is to move from a short term...
Substitution and elasticity give about the history of supply and the demand structure for fish and seafood. It is also relevant to the detection of change in a particular exploited marine ecosystem. The purpose of this paper is to test if market elasticity of substitution of seafood categories can further...
Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to
marine fisheries. While ITQs can improve the economic efficiency of fisheries, in practice they are not a
panacea and distribution and equity issues have been raised in many cases. To overcome those issues,
ITQ systems...
A lot of efforts through different projects have been made to establish comanagement
mechanisms to manage small scale fishery in Sri Lanka.
Nevertheless, many of such attempts have by now proved to be futile
endeavors. More often than not, such attempts to establish co-management
mechanisms in small scale fishery in...
While French marine fisheries must cope with increasing difficulties, the concept of
multifunctionality of fisheries (as previously observed in agriculture) is emerging
through a diversification of activities. Indeed, fishers resort to alternatives in order to
sustain their activity by calling on new ways to interact with environment, institutional
players, scientists,...
The overall aim of this research project is to determine the socioeconomic impact of a live tilapia gathering and distribution centre on rural and peri-urban fish farmers.

inspection...
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...
Japan has been the biggest export market of aquatic products of China for many years. The export of aquatic products to Japan reached more than 700,000 ton and $ 3 billion in 2007. The influence to the export market caused by the sweeping economic crisis will affect the benefits of...
In many fisheries, harvesters of different scales, different gears, or on
different sides of political boundaries crossed by a single stock are
effectively managed separately. The New England Multispecies
(groundfish) fishery is about to dramatically expand the number of
management systems in place concurrently, by allocating portions of the
total...
If the role of MPAs as a conservation tool is now widely demonstrated
even with some variability, their effects on fishery yields, tourism revenues
and social aspects are only confirmed by very few studies. More than 550
