“…Similar conclusions are reached when the effects on fisheries are analyzed considering CPUE data (Vandeperre et al, 2011). Pérez-Ruzafa et al (2008), using a modeling approach, showed that medium size to large marine reserves (>600 ha) are to be preferred to small ones, both to maximize the protection of fish populations abundance and to improve the exportation of biomass across the marine reserve boundaries , thus agreeing with empirical data. Larger reserves attain between 80 and 100% of the carrying capacity in the first 5 years after protection depending on fish mobility or fishing effort in the surrounding area.…”

“…In the last decade, modeling approaches have also analyzed the exportation of individuals on the basis of diffusive processes dependent on density gradients (Gerber et al, 2003;Neubert, 2003;Kellner et al, 2007;Pérez-Ruzafa et al, 2008), which is consistent with observed patterns in fish abundance and fishing effort distribution. Other models incorporate movement patterns-migration, ontogenetic movements, etc.…”

“…Marine fish dispersal that would benefit fisheries in the vicinity of an MPA may occur via several mechanisms: egg and larval dispersal (Cowen et al, 2000;Abesamis et al, 2016Abesamis et al, , 2017, the trophic or reproductive migrations of adults (Green et al, 2015), nomadic or ontogenetic movements (Grüss et al, 2011), and, density-independent, home-range movements by individuals across reserve boundaries and home-range relocation because of density-dependent factors (Rakitin and Kramer, 1996;Russ and Alcala, 1996;Kramer and Chapman, 1999;Pérez-Ruzafa et al, 2008). Although, all these mechanisms potentially increase the catch in surrounding areas, and hence likely benefit fisheries by helping to recover and maintain target populations, full benefits of MPAs would require protecting also other mechanisms determining reproductive success, such as those necessitating essential habitats (Elliott et al, 2016)-e.g., spawning grounds (Erisman et al, 2015;Sadovy de Mitcheson, 2016) and recruitment areas (Cheminée et al, 2017).…”

North East Atlantic vs. Mediterranean Marine Protected Areas as Fisheries Management Tool

The effectiveness of management initiatives implemented in the context of the European Common Fisheries Policy has been questioned, especially with regard to the Mediterranean. Some of the analyses made to compare the fishing activity and management measures carried out in the North East Atlantic and in the Mediterranean do not take into account some of the differentiating peculiarities of each of these regions. At the same time, they resort to traditional fisheries management measures and do not discuss the role of marine protected areas as a complementary management tool. In this respect, the apparent failure of marine protected areas in the North-East Atlantic compared with the same in the Mediterranean is challenging European fishery scientists. Application of the classical holistic view of ecological succession to the functioning of fishery closures and no-use areas highlights the importance of combining both management regimes to fully satisfy both fishery-and biodiversity-oriented goals. We advocate that an optimal management strategy for designing an MPA to protect biodiversity and sustain fishing yields consists of combining a network of no-use areas (close to their mature state) with fish boxes (buffer zones maintained by fishing disturbance in a relatively early successional stage, where productivity is higher), under a multi-zoning scheme. In this framework, the importance of no-use areas for fisheries is based on several observations: (1) They preserve biological diversity at regional scale, at all levels-specific, habitat/seascape, and also genetic diversity and the structure of populations, allowing natural selection to operate. (2) They permit the natural variability of the system to be differentiated from the effects of regulation and to be integrated in appropriate sampling schemes as controls. (3) They maintain the natural size and age structure of the populations, hence maximizing potential fecundity, allowing biomass export to occur from core to regulated areas, dampening the fluctuations derived from deviations from the theoretical optimal effort in the fishing zone.

“…Growing evidence from theoretical models and empirical studies suggests that higher abundances inside reserves can lead to spillover of adults to nearby fished areas (Rowley 1994;Roberts et al 2001;Goni et al 2008;Kellner et al 2008;Perez-Ruzafa et al 2008). Spillover is typically observed as declining patterns of abundance or catch across reserve boundaries, although there may be no detectable pattern of decline in abundance if fishing effort is intense surrounding the reserve.…”

Spillover from marine reserves and the replenishment of fished stocks

SUMMARYNo-take marine reserves are widely recognized as an effective conservation tool for protecting marine resources. Despite considerable empirical evidence that abundance and biomass of fished species increase within marine reserve boundaries, the potential for reserves to provide fisheries and conservation benefits to adjacent waters remains heavily debated. This paper uses statistical and population models to evaluate published empirical data on adult spillover from marine reserves and shows that spillover is a common phenomenon for species that respond positively to reserve protection, but at relatively small scales, detectable on average up to 800 m from reserve boundaries. At these small scales, local fisheries around reserves were likely unsustainable in 12 of 14 cases without the reserve, and spillover partially or fully offsets losses in catch due to reserve closure in the other two cases. For reserves to play a role in sustaining and replenishing larger-scale fished stocks, networks of reserves may be necessary, but as few exist this is difficult to evaluate. The results suggest reserves can simultaneously meet conservation objectives and benefit local fisheries adjacent to their boundaries.
