Fishers' perceptions as indicators of the performance of Marine Protected Areas (MPAs) ArchiMer
Leleu, Kevin; Alban, Frederique; Pelletier, Dominique; Charbonnel, Eric; Letourneur, Yves; Boudouresque, Charles F..
How users perceive the performance of Marine Protected Areas (MPAs) is fundamental for the social acceptance of these zones. Moreover, their perceptions may be relevant for monitoring the effects of MPAs on extractive activities. This study analyzes artisanal fishers' perceptions of the performance of a north-western Mediterranean coastal MPA, which encompasses two no-take zones (NTZs). Three viewpoints have been considered: the effect on the personal activity of fishers, the effect on the local fishery and the effect on the ecosystem. In order to test the hypothesis that biomass export (spillover) - which had previously been evidenced from the two NTZs - may influence fishers' perceptions of NTZ effects, fishers' perceptions were compared with both...

Mercury in blue shark ( Prionace glauca ) and shortfin mako ( Isurus oxyrinchus ) from north-eastern Atlantic: Implication for fishery management ArchiMer
Biton-porsmoguer, Sebastian; Banaru, Daniela; Boudouresque, Charles F.; Dekeyser, Ivan; Bouchoucha, Marc; Marco-miralles, Francoise; Lebreton, Benoit; Guillou, Gael; Harmelin-vivien, Mireille.
Pelagic sharks (blue shark Prionace glauca and shortfin mako Isurus oxyrinchus) caught by long-line Spanish and Portuguese fleets in the NE Atlantic, were sampled at Vigo fish market (Spain) for total mercury (Hg) analysis. Hg concentration in white muscle increased with size and weight in both species, but at a higher rate in shortfin mako than in the blue shark. No difference was found with sex, year and season. Spatial variation was observed in the blue shark with higher Hg values in the North of the Azorean archipelago, but not in the shortfin mako. These high-level predators are particularly susceptible to bioaccumulate contaminants (Hg) in their tissues (muscle). However, a significant positive relationship between Hg concentration and trophic level...

Métiers, effort and catches of a Mediterranean small-scale coastal fishery: The case of the Côte Bleue Marine Park ArchiMer
Leleu, Kevin; Pelletier, Dominique; Charbonnel, Eric; Letourneur, Yves; Alban, Frederique; Bachet, Frederic; Boudouresque, Charles F..
The overexploitation of fishery resources has led to a major fisheries crisis. In this context, artisanal fisheries, and in particular small-scale coastal fisheries, appear as relevant alternatives for a sustainable use of coastal resources. Marine Protected Areas (MPA) are more and more used as management tools for these fisheries, as protection effects and targeted access regulations may benefit to commercial fishers. Managers and scientists need then quantitative information not only to adapt their management to the fishing activity present on their territory, but also to estimate the effects of MPA management on it. This study provides catch and effort estimates that are essential for appraising and managing the artisanal fishery in the Côte Bleue...
