Feeding ecology of harbour porpoises Phocoena phocoena stranded on the Galician...
Hernandez-Gonzalez, A.; Saavedra, C.; Read, F. L.; López, A.; Gouveia, Anabela; Covelo, P.; Alonso-Fernández, A.; Velasco, F.; Santos, M BegoñaDiet studies on the endangered and genetically distinct Iberian population of the southern harbour porpoise Phocoena phocoena are scarce. The present study provides updated information on the feeding ecology of this cetacean along the Galician coast (NW Spain) over the last 3 decades (1990-2018). The stomach contents of 72 stranded harbour porpoises were analysed to determine diet composition, to study which fa...
Scottish lobster fisheries and environmental variability
Lizárraga-Cubedo, H. A.; Tuck, I.; Bailey, N.; Pierce, G. J.; Zuur, A. F.; Bova, D.Variability in the fluctuations of two Scottish lobster populations, the Hebrides and Southeast, was investigated from available long dataseries of fishery and environmental variables. In a multivariate context, relationships between selected environmental variables and the fishery data were studied at different spatial and temporal (annual, spring, and autumn) scales and from individual and overall sampled fle...
Anisakis infection in allis shad, Alosa alosa (Linnaeus, 1758), and twaite shad...
Bao, M.; Mota, M.; Nachón, D. J.; Antunes, C.; Cobo, F.; Garci, M. E.; Pierce, G. J.; Pascual, S.Spawning individuals of allis shad, Alosa alosa (Linnaeus, 1758), and twaite shad, Alosa fallax (Lacépède, 1803), were sampled from three rivers on the Atlantic coast of the Iberian Peninsula (Ulla,Minho,Mondego) during 2008 to 2013 to assess the presence of the zoonotic marine parasite Anisakis spp. larvae. The results revealed that both shad species were infected by third-larval stage Anisakis simplex s.s. an...
Essential habitats for pre-recruit Octopus vulgaris along the Portuguese coast
Moreno, A.; Lourenço, S.; Pereira, J.; Gaspar, M. B.; Cabral, H. N.; Pierce, G. J.; Santos, A. M. P.The exploitation of the common octopus Octopus vulgaris in Portugal increased 50% in the last 20 years, largely motivated by the depletion of many fish stocks. Recently, the biomass of this fishery resource sharply decreased in some areas causing serious concern among local fishermen and an effort is underway to advise on novel and sustainable management measures. In this context, the octopus pre-recruit aggreg...
Behavioural responses of sardines Sardina pilchardus to simulated purse-seine c...
Marçalo, A.; Araújo, J.; Pousão-Ferreira, P.; Pierce, G. J.; Stratoudakis, Y.; Erzini, K.The behavioural effects of confinement of sardine Sardina pilchardus in a purse seine were evaluated through three laboratory experiments simulating the final stages of purse seining; the process of slipping (deliberately allowing fishes to escape) and subsequent exposure to potential predators. Effects of holding time (the time S. pilchardus were held or entangled in the simulation apparatus) and S. pilchardus...
