Borrell y Tomás E. Díaz González. El ciclo contó...

Genetics as a tool for sustainable fishing and protection of vulnerable marine ecosystems VME

Vulnerable marine ecosystems (VMEs) are characterized by being highly vulnerable to disturbances and an impaired ability to recover that takes a long time and is not always possible. Some of these vulnerable marine habitats include seamounts, hydrothermal vents or cold water coral reefs. Cold water corals are of significant ecological value and pro...

Octopus vulgaris (Cuvier, 1797) is a cephalopod species with great economic value. In western Asturias (northwest of Spain), O. vulgaris artisanal fisheries are relatively well monitored and conditionally eco-labeled by the Marine Stewardship Council (MSC). Despite this, the Asturian octopus stocks have not been genetically assessed so far. In orde...

The fishing and aquaculture sectors are an important source of development around the globe. In Asturias (Spain), the diversity and richness of the fishing grounds of the Cantabrian Sea favored the historical settlement of a large number of communities closely linked to the marine environment and fishing resources, forming an integral part of the r...

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 asses...

1. Paracentrotus lividus is a sea urchin with an important ecological role in the Cantabrian Sea ecosystem, where its populations are in severe decline and the regional government has implemented a population restoration strategy with the aim of preserving this valuable marine resource. 2. In this study, genetic monitoring was conducted for the fir...

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-man...

Sustainable Sea is a strategy game developed for educational purposes in which players assume the role of fishermen while learning concepts related to the sustainable management of fishing resources. Players earn points as they apply sustainable policies. The game was tested on high-school students and students pursuing bachelor's and master's degr...

Food fraud involves both financial and health problems for consumers as well as conservation problems for target species worldwide. In Spain, the common name “zamburiña”, which officially only refers to the species Mimachlamys varia (the variegated scallop), is frequently mistakenly used to refer to other pectinid species, and this confuses consume...

The PERCEBES project aspires to answer questions regarding the effects of harvesting on the intertidal community and recovery potential of stalked barnacle populations after harvesting, for which a Human Exclusion Experiment has been deployed over 2 years in 4 regions: coast of Alentejo (Portugal), Atlantic Islands (Galicia, Spain), Western Asturia...

The invasive Crepidula fornicata caused major problems along the European Atlantic coast, especially in France and Netherlands where high densities leads on changes in the habitat, disturb native marine wildlife as well as it originates competition for space and food. Despite its dangerous invasive nature, regular monitoring to alert about its pres...

Environmental DNA (eDNA) can be a powerful method for assessing the presence and the distribution of aquatic species. We used this tool in order to detect and quantify eDNA from the elusive species Octopus vulgaris, using qPCRs (SybrGreen protocol). We designed species-specific primers, and set up an experimental aquarium approach to validate the n...
