assessment of french artificial reefs due to limitations of research trends may be misleading
Hydrobiologia, 2015Co-Authors: Anne Tessier, Eric Charbonnel, Patrice Francour, Nicolas Dalias, Pascaline Bodilis, William Seaman, Philippe LenfantAbstract:Artificial reefs have been deployed in France since 1968 with the principal objective of enhancing success and continuity of artisanal fishing. Over 50 % of the volume of reef material has been deployed since 2000. Because of significant expansion of reef construction and availability of new research results concerning their performance since the late 1990s, we examined status and trends of French artificial reefs. Since the review of Barnabe et al. (Artificial reefs in European seas, 2000), 35 reports have been published and are analyzed here. Fish assemblages on artificial reefs have been the focus of ecological research, with emphasis on species richness and abundance. Fish Production has been associated with the age of artificial reefs and the reef’s structural complexity. The perception of stakeholders toward artificial reefs is a notable area of investigation. Economic studies are absent. Other developments in French artificial reefs over the last 10–15 years include the discontinued use of waste materials in reef construction, more directed design of reef structure, and the inclusion of additional objectives concerning biodiversity and recreation. Recommendations here include development of long-term ecological studies of artificial reefs and the evaluation of Fishery Production, including issues such as trophic dynamics, ecological connectivity of habitats, and socio-economic studies.

spillover from six western mediterranean marine protected areas evidence from artisanal fisheries
Marine Ecology Progress Series, 2008Co-Authors: Raquel Goni, Sara Adlerstein, Diego Alvarezberastegui, Aitor Forcada, Olga Renones, Geraldine Criquet, Sandrine Polti, Gwenael Cadiou, Carlos Valle, Philippe LenfantAbstract:This study investigated spillover (biomass export) around 6 marine protected areas (MPAs) in the western Mediterranean based on catch and effort data from artisanal fisheries. The selected MPAs were Cerbere-Banyuls and Carry-le-Rouet in France, and Medes, Cabrera, Tabarca, and Cabo de Palos in Spain. These MPAs had been functional for more than 8 yr and incorporate areas of fisheries closure and restricted use where fishing is limited. We based our study on the hypotheses that, in the presence of biomass export, (1) fishing effort would concentrate close to MPA boundaries, and (2) Fishery Production, expressed as catch per unit area (CPUA), would be highest near MPA boundaries and decrease with dis- tance. We selected data from 14 'fishing tactics' using gill nets, trammel nets and bottom long-lines target- ing sparids, mullids, serranids, scorpaenids and palinurids. We analyzed the spatial distribution of effort, Fishery Production and revenues per unit area, using generalized additive models (GAMs), and we tested regression slopes of effort density and CPUA with distance to closure boundaries, using generalized lin- ear models (GLMs). GAMs allowed us to recognize habitat discontinuities or 'hot spots' of high Production in the vicinity of the MPAs, and to identify the extent of potential spillover effects in order to implement GLMs. We found evidence of effort concentration and high Fishery Production near fisheries closures for all fishing tactics analyzed and significant negative slopes for most. Revenues generally followed trends similar to CPUA. Significant negative slopes from GLM of effort density and CPUA with distance from fisheries closures were indicative of biomass export where habitats across closure boundaries had some degree of continuity. The spatial extent of spillover was consistent with species mobility and fisheries effi- ciency and extended 700 to 2500 m from Fishery closure boundaries. Our results suggest that coastal MPAs can be an effective management tool for artisanal fisheries in the region and can be extended to the rest of the western Mediterranean, as the fishing tactics studied are typical of the region.
