Combinations of 7 remarkably similar factors have led to the (partial)
failure of recent efforts to address five global or national crises. The paper
analyzes the global financial crisis, climate change, the US health care
crisis, the blue fin tuna collapse in the Atlantic Ocean and the collapse of
fish...
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...
Many developed nations have accessed the diverse benefits of recreational fisheries in their this is not yet so in developing countries, this study explored the viability of recreational fisheries in two Nigerian Lakes.
Biological resources were sampled for twelve (12) months on Lakes Asejire and Oyan all in the forest...
The clam, Galatea paradoxa has for decades been an important source of protein to the riparian communities of the lower Volta River and provides employment to about 2000 people, especially women. The fishing grounds have dwindled from 100 km from the pre-dam era to a narrow stretch of 10 km...
Before 1991, the Department of Fisheries was the sole formal fisheries management authority in Sierra Leone. This authority's management of the fisheries resulted, however, in less than 10% of the estimated annual resource rent accruing to government and in increasing the importance of resource over-exploitation. To improve stock conservation and...
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...
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 coastal ecosystem of the Pearl River Estuary (PRE) has been overfished and received a high level of
combined pollution in the past decades. The fisheries stock assessments have shown a declining
population and have led to a number of management measures, including fishing moratorium. This study
evaluated the effect...
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...
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...
