The diversity of reef ecosystems, the multiplicity of reef resource uses and the breadth of the range of the island socio-cultural contexts concerned make coral reef fisheries (CRF) management in the South Pacific a complex task. The health and state of the targeted resources depend both on ecosystem characteristics (as determined by ecological and biological factors) and on fishing pressure, whose effects are only partly known. Increasing harvests from commercial and recreational fishing increasingly overlap with traditional Subsistence activity, creating an important CRF management challenge. This paper presents a new approach to CRF assessment and monitoring by providing a set of multidisciplinary indicators. The fisheries system is assessed from three...

Assessing the impact of removing reserve status on the Abore Reef fish assemblage in New Caledonia
Provedor de dados: 5
Autores: Ferraris, Jocelyne; Pelletier, Dominique; Kulbicki, M; Chauvet, C.
We propose a statistical approach based on multivariate analysis and general linear models to test the consequences of removal of reserve status from the Abore Reef fish assemblage of the Abore Reef reserve, New Caledonia. Consequences on fish density were examined at the level of fish assemblage, accounting for habitat. Fish counts and habitat-related information were collected before and after the removal of reserve status, both inside and outside the reserve. Species groups were constructed on the basis of additional information on behavioural characteristics and taxonomy. The impact of the removal of reserve status was assessed by using 2 habitat proxies corresponding to 2 spatial scales and by considering several criteria for grouping species. Habitat...

Designing indicators for assessing the effects of marine protected areas on coral reef ecosystems: A multidisciplinary standpoint
Provedor de dados: 5
Autores: Pelletier, Dominique; Garcia Charton, Jose; Ferraris, Jocelyne; David, Gilbert; Thebaud, Olivier; Letourneur, Yves; Claudet, Joachim; Amand, Marion; Kulbicki, Michel; Galzin, René.
The present paper aims at identifying and assessing indicators of the effects of Marine Protected Areas (MPAs) in coral reef regions, based on a bibliography review in ecology, economics and social sciences. First the various effects Studied within each of these domains and the variables used to measure them were censused. Potential ecological indicators were assessed through their link with the question used (here termed "relevance") and their "effectiveness" which encompasses the issues of precision, accuracy and statistical power. Relevance and effectiveness were respectively measured by the frequency of use of each indicator and the proportion of significant results in the reviewed articles. For social and economic effects, the approach was not...

Le lagon, un patrimoine naturel et un espace de loisirs
Provedor de dados: 5
Autores: Gonson, Charles; Ferraris, Jocelyne; Pelletier, Dominique; Jollit, Isabelle.
With the worldwide growing of human populations in coastal areas, recreational activities are increasing and diversifying. New Caledonia is surrounded by a large lagoon that provides a shelter for these popular activities. Although most of the lagoon areas are managed through well-established Marine Protected Areas (MPA) and 80% of its surface is a World Heritage property, these uses result in accrued and increasing pressures on the coastal environment. This paper provides an overview of the research projects developed since 2000 to better understand and assess recreational uses in the New Caledonian lagoon. Most of these projects were conducted in collaboration with MPA, environmental managers and with stakeholders.

Considering multiple-species attributes to understand better the effects of successive changes in protection status on a coral reef fish assemblage
Provedor de dados: 5
Autores: Preuss, Bastien; Pelletier, Dominique; Wantiez, Laurent; Letourneur, Yves; Sarramegna, Sebastien; Kulbicki, Michel; Galzin, Rene; Ferraris, Jocelyne.
The response of fish assemblages to changes in protection status is a major issue for both biodiversity conservation and fishery management. In New Caledonia, the Abore reef marine reserve harbours more than 500 fish species, and has been subjected to changes in protection status since 1988. The present study investigates the impact of these changes on a wide subset of species (213), based on underwater visual counts collected before the opening and after the closure to fishing of this marine protected area (MPA). We analysed the spatial and temporal variability in fish assemblage attributable to protection status, explicitly considering habitat. To understand the successive responses of fish assemblage to fishing and protection, the assessment models...

Méthodes pour la typologie des flottilles de pêche : bilan et ouvertures
Provedor de dados: 5
Autores: Rochet, Marie-joelle; Ferraris, Jocelyne; Biseau, Alain; Sabatier, R.
Introduction: Twenty reports or articles concerning fishing fleet typology work have been analysed. All of them come from IFREMER, except for two articles; one was published by Danish researchers and the other by Americans. Our purpose here is to review and assess this work on a methodological standpoint in order to identify if the objectives announced and methods used are adequately in line.

Decadal increase in the number of recreational users is concentrated in no-take marine reserves
Provedor de dados: 5
Autores: Gonson, Charles; Pelletier, Dominique; Gamp, Elodie; Preuss, Bastien; Jollit, Isabelle; Ferraris, Jocelyne.
In coastal areas, demographic increase is likely to result in greater numbers of recreational users, with potential consequences on marine biodiversity. These effects may also occur within Marine Protected Areas (MPAs), which are popular with recreational users. Our analysis builds on data collected over a ten-year period during three year-round surveys to appraise changes in recreational boating activities in coral ecosystems. Results show that the number of boaters has greatly increased, particularly so within MPAs during weekends and the warm season, when peaks in boat numbers have become more frequent. We also observed that the number of anchored boats has increased over the period. These changes may be resulting in biophysical impacts that could be...

Sustainability of exploited marine ecosystems through protected areas: A viability model and a coral reef case study
Provedor de dados: 5
Autores: Doyen, L; De Lara, M; Ferraris, Jocelyne; Pelletier, Dominique.
Overexploitation of marine resources remains a problem worldwide. Many works advocate for the use of marine reserves as a central element of future stock management in a sustainable perspective. In the present paper, we address the influence of protected areas upon fisheries sustainability within an eco-systemic framework through a dynamic bio-economic model integrating a trophic web, catches and environmental uncertainties. The model is spatially implicit. The evaluation of the ecosystem is designed through the respect along time of constraints of both conservation and guaranteed captures. Using the mathematical concept of invariance kernel in a stochastic context, we define different MPA effects according to biodiversity catches or mixed points of view....

Influence of settings management and protection status on recreational uses and pressures in marine protected areas
Provedor de dados: 5
Autores: Gonson, Charles; Pelletier, Dominique; Alban, Frederique; Giraud-carrier, Charlotte; Ferraris, Jocelyne.
Coastal populations and tourism are growing worldwide. Consequently outdoor recreational activity is increasing and diversifying. While Marine Protected Areas (MPAs) are valuable for mitigating anthropogenic impacts, recreational uses are rarely monitored and studied, resulting in a lack of knowledge on users' practices, motivation and impacts. Based on boat counts and interview data collected in New Caledonia, we i) explored factors affecting user practices and motivations, ii) constructed fine-scale pressure indices covering activities and associated behaviors, and iii) assessed the relationships between user practices and site selection. User practices were found to depend on protection status, boat type and user characteristics. Pressure indices were...
