Recovery after exploitation of stalked barnacles is facilitated by the presence...
Gómez-del Campo, V.; Arrontes, J.; Cruz, T.; Vázquez, E.; Macho, G.; Thiébaut, E.; Geiger, K.; Fernandes, J.N.; Jacinto, D.; Aguión, A.; Silva, T.We have followed the recovery of gaps produced either by harvesters or by scientists in stands of stalked barnacle (Pollicipes pollicipes) during two years in four regions of Europe (SW Portugal, Galicia and Asturias in Spain and Brittany in France; n = 423 gaps), which was extended to four years in Asturias (n = 252 gaps). The presence of adult conspecifics in the margins of the gaps increased by at least four...
Establishing a governance threshold in small-scale fisheries to achieve sustain...
Aguión, A.; Ojea, E.; Garcia-Flórez, L.; Cruz, T.; Garmendia, J.M.; Davoult, D.; Queiroga, H.; Rivera, A.; Acuña, J.L.; Macho, G.The lack of effective governance is a major concern in small-scale fisheries. The implementation of governance that encompasses the three pillars of sustainability (social, economic, and ecological) is still a worldwide challenge. We examined nine stalked barnacle fisheries (Pollicipes pollicipes) across Southwest Europe to better understand the relationship between governance elements and sustainability. Our r...
Coping with poachers in European stalked barnacle fisheries: Insights from a st...
Geiger, K.; Rivera, A.; Álvarez, J.; Arrontes, J.; Borrell, Y.J.; Cruz, T.; Davoult, D.; Dubert, J.; Feis, M.; Fernandes, J.N.; Fernández, C.In January 2020, a stakeholder workshop was organized as a knowledge sharing strategy among European stalked barnacle fisheries. Management of this fishery differs greatly among regions and ranges from less organized and governed at large scales (>100 km, coasts of SW Portugal and Brittany in France) to highly participatory systems which are co-managed at small spatial scales (10′s km and less, Galicia and Astu...
Biophysical modelling of larval dispersal and population connectivity of a stal...
Nolasco, R.; Dubert, J.; Acuña, J.L.; Aguión, A.; Cruz, T.; Fernandes, J.N.; Geiger, K.J.; Jacinto, D.; Macho, G.; Mateus, D.; Rivera, A.; Román, S.Numerical biophysical models are a standard methodology used to provide estimates of larval dispersal and population connectivity for marine species with a bi-phasic life cycle. How- ever, confidence on biophysical models, tested by confronting model estimates with empirical evi- dence, is seldomly assessed. We compared time-series estimates of larval supply of the stalked barnacle Pollicipes pollicipes to rock...
