Large-Scale Assessment of Mediterranean Marine Protected Areas Effects on Fish Assemblages

This article is based on a large-scale assessment of multiple MPAs in the Mediterranean. The role of MPAs in reversing the effects of overfishing is studied, evenas MPAs in relation with the spread of non-indigenous-species and thermophilic species. The results contribute to 'more robuste expectations' on new MPAs in the Mediterranean and worldwide.

Spatial patterns of density at multiple life stages in protected and fished conditions: an example from a Mediterranean coastal fish

Settlement and recruitment are well known to have critical influences on the demography of most marine fishes. Few studies have compared processes like larval supply, settlement and recruitment of fishes between protected (i.e. in marine protected areas, MPAs) and unprotected conditions and little information is available about the potential influence of early life history traits (e.g. pelagic larval duration, PLD) on these processes.

Dispersal patterns of coastal fish: implications for designing networks of marine protected areas

Information about dispersal scales of fish at various life history stages is critical for successful design of networks of marine protected areas, but is lacking for most species and regions. Otolith chemistry provides an opportunity to investigate dispersal patterns at a number of life history stages. Our aim was to assess patterns of larval and post-settlement (i.e. between settlement and recruitment) dispersal at two different spatial scales in a Mediterranean coastal fish (i.e. white sea bream, Diplodus sargus sargus) using otolith chemistry.

Assessing dispersal patterns of fish propagules from an effective Mediterranean Marine Protected Area

Successfully enforced marine protected areas (MPAs) have been widely demonstrated to allow, within their boundaries, the recovery of exploited species and beyond their boundaries, the spillover of juvenile and adult fish. Little evidence is available about the so-called ‘recruitment subsidy’, the augmented production of propagules (i.e. eggs and larvae) due to the increased abundance of large-sized spawners hosted within effective MPAs. Once emitted, propagules can be locally retained and/or exported elsewhere.
