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 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...
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...
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...
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 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.
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...
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...
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 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...
We combine information from several global fisheries databases including
those from the Sea Around Us Project (www.seaaroundus.org) and the
Fisheries Economics Research Unit (http://feru.org) to project the future
potential gains in human welfare under the assumption that (i) global
fisheries continue the current declining trend observed over the last several...
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 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...
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,...
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....
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...
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...
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...
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...
