In the Atlantic Arc, the stalked barnacle fishery is managed using a variety of spatial tools ranging from open access, through Territorial User Rights for Fishers (TURFs) to Marine Reserves (MR). In addition, co-management in some places allows the emergence of new management practices, which makes this fishery an interesting example to investigate the implications of distinct spatial management options on the biology and ecology of exploited coastal species. It also provides a learning platformto guide marine spatial planning of Small Scale Fisheries in other contexts in the EU. The PERCEBES project is a Portuguese, French and Spanish initiative co-funded by the ERA-Net BiodivERsA intended as a scientific and practical demonstration of the effects of Stalked Barnacle (SB) harvesting on the biodiversity, productivity and connectivity of SB populations/stocks? both at local and landscape level. This is done through two approaches: 1-A continental-scale, Human Exclusion Experiment (HEE). By using steel cages that simulate the effects of 1 and 2 year bans and open plots as controls where harvest continues unimpeded. The HEE tests the effect of those treatments on the biodiversity, productivity and economic value of SB stands and on their potential to produce larvae. 2-Construction of regional, spatially explicit Bioeconomic Models (BM). We are building biophysical larval dispersal models to visualize the seeding effects of fallow or protected areas on other regions and the patterns of connectivity among managed or co-managed spatial units. These models are being validated by direct measurement of recruitment distributed in time and space. Additionally, the biophysical models will be coupled with landings and sales data to assess the sustainability and cost effectiveness of distinct spatial management options. These two objectives are carried out at four experimental sites: coast of Alentejo (Portugal), , NW coast of Galicia (Spain), Western Asturias coast (Spain) and South Brittany (France), covering the latitudinal range where the barnacles are exploited in the EU. PERCEBES benefits from/has the collaboration of stakeholders, fishers, administration and NGOs for site selection, experiment surveillance and sample collection. The project has established a consortium with the fishers to secure a large number of recruitment observations distributed in time and space. PERCEBES combines results from experiments, hydrodynamic models and landings data into spatially explicit bioeconomic models which will allow generation of “policyscapes” to optimize the conservation/exploitation tradeoff. This is of interest for Administrations seeking to manage the SB fishery. At a final collaborative workshop, fishers, scientists, administrators and ONGs will discuss the potential for crossbreeding of good management practices across the Atlantic Arc. PERCEBES is also producing a video documentary focused on the effects of harvesting on biodiversity patterns, intended for a general audience, and focused on the science of the interaction humans-ecosystem.
