Towards global traceability for sustainable cephalopod seafood
Gleadall, Ian G.; Moustahfid, Hassan; Sauer, Warwick H. H.; Ababouch, Lahsen; Arkhipkin, Alexander I.; Bensbai, Jilali; Elegbede, Isa; Faraj, AbdelmalekCephalopods are harvested in increasingly large quantities but understanding how to control and manage their stocks, and tracking the routes of the consumption that exploits them, lag behind what has been developed for exploiting finfish. This review attempts to redress the imbalance by considering the status of the major cephalopod stock species and the traceability of cephalopod seafood along the trade value ...
Alongside but separate : Sympatric baleen whales choose different habitat condi...
González García, Laura; Pierce, Graham J.; Autret, Emmanuelle; Torres-Palenzuela, Jesús M.Fin whales and sei whales are two migratory baleen whale species sighted every year across the waters of the Azores. Improved understanding of the ecological niche and habitat requirements of these baleen whales is needed to identify persistent or predictable oceanographic events that may set the time of their migration, as well as local or ephemeral oceanographic features that may aggregate their prey in a par...
Trophic position of dolphins tracks recent changes in the pelagic ecosystem of ...
Bode, Antonio; Saavedra, Camilo; Álvarez-González, Miguel; Arregui, Marina; Arbelo, Manuel; Fernández, Antonio; Freitas, Luís; Silva, Mónica A.Dolphins play a key role in marine food webs as predators of mid-trophic-level consumers. Because of their mobility and relatively long life span, they can be used as indicators of large-scale changes in the ecosystem. In this study, we calculated the trophic position (TP) of 5 dolphin species from the Canary, Madeira and Azores Islands using bulk and compound-specific stable isotope ratios from muscle tissue t...
The significance of cephalopod beaks as a research tool: An update
Xavier, José C.; Golikov, Alexey V.; Queirós, José P.; Perales-Raya, Catalina; Rosas-Luis, Rigoberto; Abreu, José; Bello, Giambattista; Bustamante, PacoThe use of cephalopod beaks in ecological and population dynamics studies has allowed major advances of our knowledge on the role of cephalopods in marine ecosystems in the last 60 years. Since the 1960's, with the pioneering research by Malcolm Clarke and colleagues, cephalopod beaks (also named jaws or mandibles) have been described to species level and their measurements have been shown to be related to ceph...
Fisheries for common octopus in Europe: socioeconomic importance and management
Pita, Cristina; Roumbedakis, Katina; Fonseca, Teresa; Matos, Fábio L.; Pereira, João; Villasante, Sebastián; Pita, Pablo; Bellido, José MariaThe European Union (EU) is one of the most important markets for cephalopods in the world. Currently, small-scale fisheries targeting the common octopus in the EU are of considerable social and economic importance, especially in southern European waters where more octopus are consumed as part of the traditional diet. Octopuses in Europe are excluded from quota regulations under the Common Fisheries Policy and E...

Stranding patterns and feeding ecology of striped dolphins, Stenella coeruleoal...
Marçalo, Ana; Giménez, Joan; Nicolau, Lídia; Frois, Jessica; Ferreira, Marisa; Sequeira, Marina; Eira, Catarina; Pierce, Graham J.; Vingada, JoséThe striped dolphin, Stenella coeruleoalba, is one of the most abundant cetacean species off the Western Iberian coast, however, studies on the species regarding biology, ecology, threats or conservation efforts are lacking. This study investigates stranding patterns (years 1981–2014) and diet (2002–2014) of striped dolphins (Stenella coeruleoalba) off the Portuguese mainland coast. Stranded animals were sample...
Trends and drivers of marine fish landings in Portugal since its entrance in th...
Bueno-Pardo, Juan; Pierce, Graham J.; Cabecinha, Edna; Grilo, Catarina; Assis, Jorge; Valavanis, Vasilis; Pita, Cristina; Dubert, JesusMarine landings in Portugal have decreased at a higher rate than fishing effort in the last 20 years. Identifying the variables driving the quantity and composition of landings is pivotal to understand the dynamics of the fisheries sector, which entails complex social and environmental aspects. In this study, we investigate the main drivers of marine fish landings in continental Portugal between 1989 and 2014. ...
