Do pingers cause stress in fish? An experimental tank study with European sardi...
Goetz, Sabine; Begoña Santos, M.; Vingada, José; Costas Costas, Damián; González Villanueva, Antonio; Pierce, Graham JohnAcoustic deterrent devices (pingers) that are designed to alert marine mammals to the presence of fishing gear have been successfully employed to reduce cetacean–fishery interactions. However, pinger sounds may affect fisheries target species: noise can induce short-term stress responses in fish that are reflected in increased blood cortisol concentrations and behavioural alterations, which may ultimately resul...
Cetacean occurrence, habitat preferences and potential for cetacean-fishery int...
Goetz, Sabine; Read, Fiona L.; Ferreira, Marisa; Martínez Portela, Julio; Begoña Santos, Maria; Vingada, José; Siebert, Ursula; Marçalo, AnaIberian Atlantic waters are heavily exploited by Spanish and Portuguese fisheries. Overlaps between fishery target species and cetacean diet, and between fishing grounds and cetacean foraging areas, can lead to cetacean–fishery interactions including bycatch mortality of cetaceans. The present study assesses cetacean distribution, habitat preferences and hotspots for cetacean–fishery interactions by using a coo...
Interactions of cetaceans with Spanish and Portuguese fisheries in Atlantic wat...
Goetz, SabineWith the aim to provide new insights into operational cetacean-fishery interactions in Atlantic waters, this thesis assesses interactions of cetaceans with Spanish and Portuguese fishing vessels operating in Iberian and South West Atlantic waters. Different opportunistic research methodologies were applied, including an interview survey with fishers (mainly skippers) and onboard observations by fisheries observ...
