Marine reserves: size and age do matter
Joachim Claudet,Craig W. Osenberg,Lisandro Benedetti-Cecchi,Paolo Domenici,José-Antonio García-Charton,Angel Pérez-Ruzafa,Fabio Badalamenti,Just T. Bayle-Sempere,Alberto Brito,Fabio Bulleri,Jean-Michel Culioli,Mark Dimech,J.M. Falcón,Ivan Guala,Marco Milazzo,Julio Sánchez-Meca,Paul J. Somerfield,Ben Stobart,Frederic Vandeperre,Carlos Valle,Serge Planes +20 more
TL;DR: Using 58 datasets from 19 European marine reserves, it is shown that reserve size and age do matter: Increasing the size of the no-take zone increases the density of commercial fishes within the reserve compared with outside; whereas thesize of the buffer zone has the opposite effect.
Journal ArticleDOI
Multi-scale spatial heterogeneity, habitat structure, and the effect of marine reserves on Western Mediterranean rocky reef fish assemblages
José Antonio García-Charton,José Antonio García-Charton,Angel Pérez-Ruzafa,Pablo Sanchez-Jerez,Just T. Bayle-Sempere,Olga Reñones,D. Moreno +6 more
TL;DR: The hypotheses that species abundance and the biomass of reef fish populations is higher within than outside marine reserves, and that a north-to-south geographical gradient of these variables exists are tested, and causes of the observed patchiness of Mediterranean reef fish assemblages are probably multiple.
Journal ArticleDOI
Attraction of wild fish to sea-cage fish farms in the south-western Mediterranean Sea: spatial and short-term temporal variability
Tim Dempster,Pablo Sanchez-Jerez,Just T. Bayle-Sempere,Francisca Gimenez-Casalduero,Carlos Valle +4 more
TL;DR: It is suggested that coastal sea-cage fish farms may act as small (up to 160 000 m 2 ), pelagic marine protected areas (MPAs) at farms where wild fish are abundant and ecolog- ical interactions that may influence both wild fish stocks and the impact of farms must be considered.

Gradients of abundance and biomass across reserve boundaries in six Mediterranean marine protected areas : Evidence of fish spillover?
Mireille Harmelin-Vivien,Laurence Le Direach,Just T. Bayle-Sempere,Eric Charbonnel,José Antonio García-Charton,Denis Ody,Angel Pérez-Ruzafa,Olga Reñones,Pablo Sanchez-Jerez,Carlos Valle +9 more
TL;DR: In this article, the existence of gradients of fish abundance and biomass across marine reserve boundaries was assessed in six Mediterranean MPAs using underwater visual censuses performed at various distances from the core of the MPA, in integral reserve (IR), to buffer zone (BZ) and fished areas.
Journal ArticleDOI
Coastal salmon farms attract large and persistent aggregations of wild fish: an ecosystem effect
Tim Dempster,Ingebrigt Uglem,Pablo Sanchez-Jerez,Damian Fernandez-Jover,Just T. Bayle-Sempere,Rune Nilsen,Pål Arne Bjørn +6 more
TL;DR: Estimates indicate that salmon farms attract and aggregate over 12 000 t of wild fish into a total of just 750 ha of coastal waters on any given day in Norway, with possible consequences of these persistent, substan- tial aggregations of wild fishes at farms.
