The coastal fishery in French Guyana is a challenging case study for the implementation of the ecosystem based fishery management. Although the current situation of this small scale fishery could be considered as satisfactory, the viability of the fishery can be questioned. Indeed according to demographic scenarios, the growth of...
The credit crunch has had a dramatic effect within the seafood industry. Recent years saw a buoyant UK economy with increasing sales of chilled seafood material and a growing interest in sustainability. Credit tightening and declining consumer confidence has placed pressures on these trends. This is unlikely to be reversed...
This paper is based on a review and assessment of lessons from three
projects on fisheries co-management in Bangladesh: i) Community-based
fisheries management (CBFM), ii) Management of aquatic ecosystems
through community husbandry (MACH), and iii) Fourth Fisheries Project
(FFP). These co-management initiatives established 191 Community Based
Organizations (CBOs) in 179...
Many renewable resources, such as fish stocks, water or environmental
quality, are shared between different countries. The management of such
resources then relies on international agreements. We develop a model of a
shared renewable resource for which there is an international agreement
that determines each country's share of total extractions....
This paper develops a theoretical framework to assess resources management procedures from a sustainability
perspective, when resource dynamics is marked by uncertainty. Using stochastic viability, management procedures
are ranked according to their probability to achieve economic and ecological constraints over time. This framework
is applied to a fishery case-study, facing...
Eritreas Coastal Marine and Island area covers more than 121,000km2, include over 350 offshore islands and 1,350km of coastline (18% of the Red Sea continental coastline) not including the islands. The total coastal mainland population is 73,000, and only ten out of all the islands are inhabited with a total...
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...
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...
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. Classic strategies (like precautionary approach of the International Council for the Exploration of the Sea, ICES) were compared to...
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...
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,...
To ensure the long-term conservation and sustainable use of straddling fish stocks, the 1995 United
Nations Fish Stock Agreement calls for the establishment of regional fisheries management organizations
to manage such stocks. This paper studies the potential for cooperation in straddling stock fisheries when
the cooperative coalition of countries acts...
This paper addressed the budgeting analysis of catfish marketing in Ondo
State. The catfish sellers were interviewed from the market with the aid of
structured questionnaire and personal interviews. Data were collected using
simple random sampling technique from fifty (50) marketers. The data
collected were analyzed using frequencies, percentages, profitability...
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...
There is a consensus in the scientific community that overexploitation of most fisheries worldwide has had significant negative effects on coastal marine ecosystems, and the majority of assessed fish stocks still require rebuilding programs. Almost all of the scientific studies conducted in recent decades have focused primarily on analysis related...
This paper deals with the sustainable management of a renewable resource
based on individual and transferable quotas (ITQs) when agents differ in terms of
harvesting costs or catchability. In a dynamic bio-economic model, we determine
the conditions under which the manager of an ITQ system can achieve sustainability
objectives which...
Fisheries and aquaculture are part of a complex system with underlying
relationships between species and other activities. This calls for more
integrated assessment, leaving a management based on stock assessment
and single species. The ecosystem approach for fisheries management
(EAF) as well as the more recent ecosystem approach to aquaculture...
Aquaculture and fisheries are essential resources for the agri-food
production of the north Adriatic coast. In particular mussels farms occupy a
large area of the gulf of Trieste. A total of 16 producers, working in small
cooperatives or individually, utilize 30 vessels on the 15 km of mussels
long-line along...
Every fish species is part of a complex ecosystem which competes with
other species for resources. Likewise, the harvesting of fish species often
involves technological interactions which results in catching multiple
species as well as temporal interactions between species as fishermen
allocate their effort across multiple fisheries over the course...
This contribution employs a „fish chain‟ approach or ocean to plate analysis to examine key market drivers affecting Northern Gulf cod fisheries recovery since their collapse in the early 1990s. Drawing upon the backward bending supply model of fisheries; secondary data was compiled and analyzed for the pre- and post-collapse...
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...
Marine scientists and stakeholders are increasingly advocating ecosystembased
fishery management (EBFM). However, the way to operationalize
such EBFM remains controversial. The viability approach can be a relevant
modelling framework for EBFM as it accounts for dynamic complexities,
uncertainties, risks and sustainability objectives balancing ecological,
economic and social dimensions together with...
The PNBA is one of the largest MPAs in Africa. Only subsistence fishing
by resident populations is authorized either on foot or using non-motorized
dories, limited in number to 100.
A development policy was adopted in 1998 to benefit the resident
population by: (i) re-deploying fishing effort targeting a non-sustainable...
In Africa, the artisanal fishing plays a crucial role in the economy and
nutrition of populations. She participates in the equilibrium of the balance
of payments, and generates significant jobs. On the coast of Senegal in
particular, artisanal fisheries ranked first in economic activities. It carries
more than 1.8% of...
Pangasius culture in recent years has proved its ability to contribute to national wealth and prosperity. As far as domestic consumption is concerned, pangasius represents an important source of nutrient intake for a large portion of the population. Multiple effects have been generated through large-scale exports, which is associated with...
In Indonesia, shrimp pond development and shrimp production expended significantly. There are also signs that this expansion has caused an environmental damaged, especially on the existence on mangrove forest. This extensification or expansion process has been facilitated by the national government through various support programs. Another important factor affecting the...
The ecosystem approach to fisheries (EAF) challenges the sustainable
management of resources at an ecosystem level facing human well-being
and environmental health. Here we describe how economic analyses may
fill important knowledge gaps for such a challenge when regarding a
broader multispecies context, e.g. tracking signals of change in ecosystem...
Commodity chains for canned tuna are global, with fishing grounds in all the oceans, processing centers
on every continent and end markets equally widespread. A tuna caught by a Taiwanese vessel in the
exclusive economic zone of Kiribati in the Pacific may be transported to a cannery in Thailand by...
The profitability of the Mediterranean mussel (Mytilus galloprovincialis) farming depends on a combination of factors including natural productivity, technical practices, production costs and product pricing. In an effort to analyse the financial risks of the mussel farming in Greece, we examined the profitability of the different farm sizes (1 to...
A group of 75 children from 3 to 5 years old from the earliest stages of a Spanish school were the target
of an experimental test focused on the consequences of providing information about safety and fisheries
sustainability on their preferences when choosing between different seafood presentations and labels.

The fishery sector is important in Nigeria’s development matrix. The sector not only
provides employment for the citizens but also contributes more than 40% of animal protein consumed by average Nigerian. However, over the years the role of providing animal protein for the populace dwindled to the extent that fish...
In the standard economic approach to optimal allocation, aggregate
economic benefit is maximised where the sustainable harvest is allocated
so that marginal net benefits are equal. The model assumes a known
sustainable harvest. It also assumes optimal intrasectoral allocation in each
sector. The Western Australian West Coast demersal fishery, like...
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...
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...
