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...
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 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 focuses on the consequences of managing small-scale fisheries without consideration of geographical differentiation in reproductive potential through a species range. Because fishing costs
increase with distance, the alternative port locations are predicted to have substantially different impacts on biological and economic performance variables when there are no spatial...
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...
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...
There is growing recognition worldwide that the impacts of fishing on non-targeted components of marine ecosystems should be included in the assessment of fisheries sustainability. This leads to the inclusion of new constraints in evaluations of the long-term bio-economic performance of fisheries. In this paper, we analyze the implications of...
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....
