Abstract Marine reserves have been identified as an important tool in the management of fishery resources and their number is increasing rapidly, most of them being on islands. However, knowledge on the real effect of protection from fishing on the genetic structure of populations, the spatial scales involved, or the suitability of islands as reserves in terms of connectivity, is scarce. This paper analyses the effects of fishery protection on the genetic structure of populations of Diplodus sargus, a target species, in protected and non-protected areas of the western Mediterranean. Populations studied showed high genetic variability at spatial scales from 101 to 103 km. Protected areas have significantly higher allelic richness. The lower levels of heterozygosis and higher heterozygote deficit showed by islands compared with coastal areas makes clear the importance of considering the connectivity processes when designing a MPA.

- Foraging behavior can influence dispersal of marine organisms (2007, background): “In this case, a network of marine protected areas would not harm genetic variation among species but in fact could promote variation across broad geographic scales, as has been recently demonstrated (Perez-Ruzafa et al. 2006).”
- Documented and Potential Biological Impacts of Recreational Fishing: Insights for Management and Conservation (2006, background): “The reserves can form an insurance against the detrimental effects of selective fishing and contribute to the protection of the genetic diversity, if their design encourages and sustains large populations, if there is no extremely strong density dependence in juvenile or adult fecundity, and if ther”
