“…To safeguard this biodiversity, the Abrolhos National Marine Park was created, encompassing 880 km 2 . Marine protected areas (MPAs) are known to benefit population recovery by increasing the abundance and size of individuals, therefore contributing to egg and larval export (Félix‐Hackradt et al, 2018; Harrison et al, 2012), besides providing high‐quality habitat for settlement (Lima et al, 2023). By demonstrating that Abrolhos Marine Park serves as a settlement ground beyond being a refuge for the adult population, this MPA can contribute to sustainability of local fisheries.…”

The age and daily growth of fish are registered through the deposition of increments in their otoliths, which are concretions formed by the precipitation of substances present in the endolymphatic fluid, mainly calcium carbonate (CaCO3). Faced with the need to fill some of the gaps in the knowledge on the occurrence and duration of the initial stages of snapper species' life cycles in the Abrolhos Bank, this study aimed to describe the growth rates, age, and period of pelagic larval duration (PLD) of three snapper species during the larval pre‐settlement phase, in the Abrolhos Bank region. The post‐larvae were captured using light traps. Otoliths were removed from 117 samples of snapper species; however, only 69 were viable for age estimation, of which 15 were Lutjanus analis, 25 were Lutjanus jocu, and 29 were Lutjanus synagris. Together, the samples presented individuals with total lengths ranging from 16.14 to 24.76 mm and ages from 21 to 39 days. Settlement marks were found for all three species, and the average PLD was ~25 days. The somatic growth of the snapper species was positively correlated with otolith growth. L. jocu presented the greatest daily growth compared to the other species. The three species use the Abrolhos Bank as a larval settlement site, demonstrating plasticity by using different habitats throughout their lives.

“…The review of recruitment studies conducted in MPAs in the north-western Mediterranean showed no difference in survival of newly-settled littoral fish between MPAs and areas outside of them, while for older recruits mortality was higher inside the MPA, probably due to the greater abundance and size of predators. In a multispecies study carried out in the Southwestern Mediterranean, Félix- Hackradt et al (2018a) found that postlarvae abundance of commercial species were negatively related to protected areas, while the distribution of juveniles did not show any protection effect, due to a high spatial variability. Multiple factors can preclude to find effect of protection on recruitment.…”

“…Carter et al (2017), calculating the annual egg production per unit area for the commercially important Plectropomus leopardus, on fished and no-take reserves throughout the Great Barrier Reef in Australia, found that egg production within no-take areas was up to 152% greater compared to areas open to fishing, although they found areas with 56% less acting as recruitment sinks. Many factors as geographic region, hydrodynamic conditions, protection status, fish size or population density affect egg production which is spatially variable (García-Charton et al, 2008;Carter et al, 2017;Félix-Hackradt et al, 2018a). Moreover, increased egg production from no-take areas may be irrelevant if recruitment is already at saturation levels, and post-recruitment processes such as food availability and predation determine or limit adult populations (Evans et al, 2008).…”

Marine protected areas (MPAs) are globally important environmental management tools that provide protection from the effects of human exploitation and activities, supporting the conservation of marine biological diversity, habitats, ecosystems and the processes they host, as well as resources in a broad sense. Consequently, they are also expected to manage and enhance marine ecosystem services and material, non-material, consumptive and non-consumptive goods, and benefits for humans. There is however certain confusion on what constitutes an ecosystem service, and it is not always easy to distinguish between them and societal benefits. The main nuance is that an ecosystem service is the aptitude an ecosystem has or develops naturally or as consequence of a management action, and that manifests through its own properties (productivity, diversity, stability, quality of its key parameters, etc.), while a societal benefit is the economic or other profitability (emotional, educational, scientific, etc.) that humans obtain from said service or quality. In this work, 268 publications, together with our own experiences in the different investigations carried out in the MPAs that are part of the BiodivERsA3-2015-21 RESERVEBENEFIT European project, have been selected, reviewed and discussed to analyze the knowledge status of the expected ecosystem services of MPAs and the societal benefits derived from them, sometimes providing information on their evidence, when they exist. We define and classify the effects of protection, ecosystem services and societal benefits and elaborate a conceptual model of the cause-effect relationships between them.

“…When designing and implementing MPAs it is important to acknowledge the different types of connectivity including active migrations and passive dispersal as well as the movements and needs of different life-stages (Fe ´lix- Hackradt et al 2018). It is also important to separate between typical home ranges and maximum migration distances since home ranges reflect scales relevant for population dynamics while maximum distances are more important for the genetic variation between populations (Bergstro ¨m et al 2007).…”

Marine protected areas (MPAs) have become a key component of conservation and fisheries management to alleviate anthropogenic pressures. For MPA networks to efficiently promote persistence and recovery of populations, ecological connectivity, i.e. dispersal and movement of organisms and material across ecosystems, needs to be taken into account. To improve the ecological coherence of MPA networks, there is hence a need to evaluate the connectivity of species spreading through active migration and passive dispersal. We reviewed knowledge on ecological connectivity in the Baltic Sea, Kattegat and Skagerrak in the northeast Atlantic and present available information on species-specific dispersal and migration distances. Studies on genetic connectivity are summarised and discussed in relation to dispersal-based analyses. Threats to ecological connectivity, limiting dispersal of populations and lowering the resilience to environmental change, were examined. Additionally, a review of studies evaluating the ecological coherence of MPA networks in the Baltic Sea, Kattegat and Skagerrak was performed, and suggestions for future evaluations to meet management needs are presented.
