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...
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...
It is widely accepted that in sea bottom areas where there is a scarcity of rocky formations and declining marine fish due to fisheries pressure, the deployment of artificial reefs (ARs) is a possible way to mitigate the problem. If ARs have an ecosystem-based fisheries management goal that means their...
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...
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 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...
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 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...
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...
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...
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.
Both...
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...
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 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.
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...
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...
The majority of monitored fish stocks globally is fully or over exploited, that is, at or below their maximum sustainable yield stock levels. Despite this resource situation international trade in fish products have been increasing for a long time. An export tax on fish and fish products, as an alternative...
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...
