Trawling for cephalopods off the Portuguese coast—Fleet dynamics and landings composition

Collection and validation of self-sampled e-logbook data in a Mediterranean demersal trawl fishery

“…These data also allow assessment of fisheries' interactions with target stocks and the environment (Fonseca et al, 2008;Lee et al, 2010;Mullowney and Dawe, 2009;Rijnsdorp et al, 1998). Accordingly, the integration of the VMS with landing data (collected through mandatory logbooks) has received considerable attention in the last few years (Bastardie et al, 2010;Gerritsen and Lordan, 2011;Hintzen et al, 2012;Martín et al, 2014;Russo et al, 2014).…”

Essential habitats for pre-recruit Octopus vulgaris along the Portuguese coast

“…The recruitment grounds in the proximity of Ria de Aveiro and close to Ria Formosa are areas subject to intense fishing activity: the artisanal fishery (traps and pots) exploits the inshore part and the bottom trawl fishery exploits the offshore part of those recruitment grounds (Fonseca et al, 2008). In principle, Portuguese fishery regulations determine that small animals (<750 g) are to be returned to the water if caught, which if respected would suffice to maintain the safety of octopus recruitment grounds, regardless of the type of activity in the area.…”

Application of a vessel monitoring system to advance sustainable fisheries management—Benefits received in Taiwan

“…Murawski et al [25] used this information to evaluate the spatial distribution of otter trawl fishing effort after the imposition of a marine protected area (MPA) off the northeastern USA. Fonseca et al [33] also used this information to demonstrate the existence of cephalopod targeting strategies in Portuguese fish trawling activities. The principal area designated for fisheries in the German EEZ in the application of 'marine spatial planning' was also defined using VMS [34].…”
