1. Introduction
Marine protected areas (MPAs) are an important instrument for
conservation and fisheries management. MPAs can protect habitats,
ecosystem structure, functioning and integrity, and species diversity,
richness, size and density [1–3]. These conservation and fisheries
benefits are particularly evident in “no-take” MPAs [4]. Their
import as a management tool has lead to increasing numbers of
MPAs around the world – more than 6800 MPAs covering 2.86%
of Exclusive Economic Zones in 2010 [5] – and global commitments
to scale up the coverage of MPAs to 10% aerial coverage by 2020 [6].
