Elevated participation in co-management increases the willingness of stalked ba...
Geiger, Katja J.; Rivera, Antonella; Aguión, Alba; Barbier, Marine; Cruz, Teresa; Fandiño, Susana; García-Flórez, Lucia; Macho, GonzaloEnsuring the sustainability of European stalked barnacle fisheries requires effective management strategies. Insights into the experience of resource users with different management strategies can help to assess their success. To explore the opinion of the harvesters on the management of local fisheries, we conducted a multi- regional survey in Spain, Portugal and France with varying degrees of co-management. W...
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...
Chaotic Genetic Patchiness in the Highly Valued Atlantic Stalked Barnacle Polli...
Parrondo, M.; Morán, P.; Ballenghien, M; Acuña, J.L.; Arrontes, J.; Chiss, J.; Cruz, T.; Fernandes, J.N.; Garcia-Flórez, L.; Garcia-Vázquez, E.The stalked barnacle Pollicipes pollicipes inhabits rocky shores from the Atlantic coasts of Brittany (France) to Senegal. Because of the culinary traditions of southern Europe, stalked barnacles represent an important target species for local fisheries on the Iberian Peninsula. To manage this fishery sustainably, it is therefore important to assess the dynamics of local populations over the Iberian coast, and ...
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...
