This paper studies the consequences of creating a marine protected area (MPA) on a recreational non-extractive use of the ecosystem (scuba diving), and draws a parallel with the impact of MPAs on
commercial fishing. The first part of the paper presents some preliminary results of a field survey of scuba...
Establishing marine protected areas (MPAs) often results in fishers being
displaced from at least some of their existing grounds. A direct
consequence of this is that governments may be required to make
compensatory payments to the firms that are affected. Experience has
demonstrated that these payments can be significant, as...
This paper investigates interactions between recreational and commercial fisheries. It introduces the idea of a protected area for recreational fisheries, as a way to reduce conflicts between the two sectors and to preserve the natural resource. It is demonstrated that without a protected area for recreational fisheries, open access may...
This paper analyzes the effects of spatial closures on the multi-species
groundfish trawl fishery in northern and central California. The analysis
differentiates between changes in total effort and in the spatial distribution
of effort before and after implementation of the closures. We use logbook
data on the location and duration...
Indian Ocean Tuna fisheries after a rapid development period from
seventies to the end of the last century are faced with challenges including:
the fishing capacity control, the profitability improvement, and the
limitation of impacts on high seas biodiversity. In this area, tuna species
are exploited by coastal states as...
This paper presents the findings of a field survey carried out within small scale fishing communities on the island of Zanzibar in 2004. The study was designed to assess the impact of the Menai Bay marine protected area on the livelihoods of fishing households located within its boundaries using the...
The northwest coast of Mexico is accountable for almost 70 % of the
country´s fishery production. This region, which includes the Gulf of
California and the Pacific coast of the Baja California Peninsula, is also
extremely important in terms of biodiversity and the presence of endemic
species. Consequently, eleven marine...
A survey was conducted to create a comprehensive list of marine protected areas (MPAs) in Japan. There
exist more than 1,000 fishery cooperatives in Japan, and many of them have established no-take zones for
many years. Such zones are usually not reported to the government and, therefore, the complete picture...
Artisanal fishermen are the great unknown of fisheries. Being the more
numerous segment, is the more abandoned community by managers. In a
generalized context of overcapacity and taking into account the dwindling
state of resources, the situation seems to be paradoxical since artisanal
métiers are considered to be the less...
The PNBA is one of the largest MPAs in Africa. Only subsistence fishing
by resident populations is authorized either on foot or using non-motorized
dories, limited in number to 100.
A development policy was adopted in 1998 to benefit the resident
population by: (i) re-deploying fishing effort targeting a non-sustainable...
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 consequences of creating a marine protected area (MPA) on
recreational extractive and non-extractive uses...
Management changes in the coral reef fin fish fishery of the Great Barrier
Reef provide a natural experiment of the efficacy of combining no-take
areas and dedicated catch shares. A spatially-explicit bio-economic model
of the fishery is used to analyze the tradeoffs between biomass and the net
returns from fishing...
Methodological difficulties, particularly when multifleet-multispecies fisheries are active, explain pro parte a weak research effort on the socio-economic impact of fishery activities after the implementation of a marine protected area. Two components of the socio-economic impact have been prioritized: the fishing unit profitability and the fishery household income distribution by...
Economists and biologists have recognized that spatial and temporal area-closures may provide an effective means of managing the impact that fisheries have on one another and upon threatened species. To date, however, little work has been done to estimate the economic impact of protected areas on commercial fishing. One significant...
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....
Marine Protected Areas (MPAs) can be considered as one of powerful conservation tools of fishery resource management in the literature. However, due to continuing environmental awareness and mismanagement, the Philippine government has decentralized the power of legislation and management of its MPAs since the early 2000. This encouraged participation of...
There is considerable debate in the literature about the usefulness of Marine Protected Areas as fishery management tools. While most economists have found that it is unlikely that marine reserves will improve steady-state yields, some biologists have shown that protected areas have the potential to reduce uncertainty. Most of the...
One of the most significant obstacles in the implementation of marine protected areas (MPA's) in developing countries is the development of alternative livelihood strategies for local people affected by a new MPA.
This presentation will discuss results from livelihoods interventions around one marine protected area case study in Vietnam, the...
Are Marine Protected Areas positive for adjacent fisheries? This is a study of the technical efficiency of small-scale trawlers in Nha Trang, Vietnam following establishment of Nha Trang Bay Marine Protected Area (NTB-MPA) that imposed a trawl ban to protect marine biodiversity and regenerate fish stocks. Data were collected through...
