Recent reports of fishery collapse paint a gloomy picture of the ocean's future; perhaps 100% of fisheries from the world's large marine ecosystems (LMEs) will be collapsed in just 40 years. While poor fisheries governance is now widely regarded as the cause, bioeconomic theory and anecdotal evidence suggest that rights-based...
This paper addresses to a comparative approach of long term changes in the characteristics of marine fisheries at a regional scale, in three ecosystems: up-welling, tropical and temperate. The South Moroccan
continental shelf, under the influence of the Canary current, where up-wellings take place, is the most productive part of...
Though the basic purpose of MPAs is marine ecosystem conservation, the question of their influence on the local economy is often critical since it governs their social acceptability. This paper addresses the
problem of measuring the local economic impact of MPAs, on the basis of a comparative analysis of socio-economic...
This paper, that follows from the ongoing Ecost project, departs from the reality of marine biodiversity degradation in the Caribbean. It first enquires how local fishing communities appreciate and measure the degradation of marine biodiversity. In this connection, it asks whether communities have social and cultural attachments to particular species....
There is increasing awareness of and concern about the actual and potential adverse effects of fishing on the aquatic environment. New Zealand, like many other countries, has developed a range of initiatives to address specific issues related to the effects of fishing, including establishing marine reserves, fishing method restrictions, observer...
Increasingly fishery managers are expected to take an ecosystem approach to fisheries management that accounts for the interrelationships of target species as well as non-target species and habitat. Fishery managers would benefit from coupled ecological-economic models that includes both the human and ecological aspects of the fishery and incorporates them...
This paper explores the issue of using marine reserves in combination with quotas as fisheries management tools. The underlying biological dynamics are described by a patchy environment model, in which a metapopulation is built up by linked sub-populations that are distributed across a set of spatially discrete habitats or patches....
Recently the ecosystem based management have been dealt with in management as a useful approach for fisheries. The goal of ecosystem-based management are sustainable management of fisheries and other marine resource through establishment of well-managed network of marine protected areas. Despite a number of benefits from marine reserve such as...
In 1998, the Florida Keys National Marine Sanctuary initiated the “Tortugas 2000” planning process that would lead to the eventual designation (2001) of the largest marine reserve in the US: The Dry Tortugas Ecological Reserve (DTER). This resulting research, targeted commercial fishermen operating in the DTER region, determining the total...
New Zealand marine recreational fisher’s attitudes to their fisheries and fisheries management are discussed in the light of the findings from two studies. The first study, a national telephone survey of more than 600 fishers, investigated why fishers seek to go recreational fishing and their attitudes towards the fisheries management....
Over the past 50 years, most efforts to regulate fishing and conserve our oceans and seas only have had limited success in preventing the on-going problems of over-fishing, degradation of the marine environment, and irreversible loss of marine biodiversity. Ecosystem-Based Management (EBM) of the oceans is an approach that is...
In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries...
Traditional approaches to fisheries management, which have been singular, species-based and non-sectoral, have failed to protect the world’s fisheries resources. This has resulted in the overexploitation of fish stocks, displacement of fishing fleets and dislocation of fishing communities. The first attempts at international regulation of fisheries were simple, but premised...
At a hearing about the Green Paper (an analysis of the EU fisheries policy over the last 10 years and an outlook for the next decade) the following statement was given by an economist: „The Ecosystem Approach is the fata morgana of the fisheries biologists.“ Indeed, a lot of biologists...
The inclusion of ecosystem considerations in fisheries management implies two changes with extensive institutional repercussions: the uncertainties about states and outcomes rise dramatically and a multiplicity of new stakeholders, interests and objectives must be accommodated in the management institutions. The first change may potentially add immense costs to the management...
In 1998, the National Marine Fisheries Service (NMFS) launched a series of marine recreational angler expenditure survey in the Northeast (NE) management region (Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Delaware, Maryland, and Virginia). This series was extended to the Southeast (SE) management region (North Carolina,...
Marine ecosystems are generally more extensive and complex than terrestrial ecosystems. Our understanding of the ecological relationships and biological processes within marine ecosystems is rudimentary but improving. In addition, our appreciation of the range of goods and services available from the marine environment and demand for competing economic uses of...
Seven economic instruments including property right regime, tradable permit, bond and deposit refund, liability, fiscal instrument, financial instrument, and charge system were considered for rehabilitations of coastal resources including mangrove, coastal water, coral, sea grass and seaweed, tourism, and fishery resources. Criteria on selective economic instruments were previous practice, management...
