Black scabbardfish (Aphanopus carbo) longline fishery off the Portuguese contin...
Campos, Aida; Leitão, Pedro; Sousa, Luís; Henriques, VictorThe main objective of this study is to provide, for the first time, fisheries-dependent, spatially explicit information on the activity for the black scabbard fish (Aphanopus carbo) longline fleet operating off the Portuguese coast. Fisheries monitoring data were analysed, covering the period 2014-2016, aiming at identifying deep-sea fishing grounds, gaining a better understanding of the fleet spatial dynamics,...
Spatial patterns of fishing activity inside the Gorringe bank MPA based on VMS,...
Campos, Aida; Leitão, Pedro; Sousa, Luís; Gaspar, Patrícia; Henriques, VictorIn this study, the fishing distribution and intensity over the Gorringe bank, a large oceanic underwater mountain located in the NE Atlantic, Natura 2000 Network MPA inside Portugal's EEZ is evaluated in the period from 2012 to 2016. Based on the combined analysis of fisheries-dependent data comprising Vessel Monitoring System (VMS), Automatic Identification System (AIS) and electronic logbooks available for th...
AUMENTO DA EFICIÊNCIA ENERGÉTICA EM ARRASTÕES COSTEIROS ATRAVÉS DA UTILIZAÇÃO D...
Parente, Joaquim; Fonseca, Paulo; Henriques, Victor; Campos, AidaTrawling is a fishing technique associated with an intensive consumption of fuel and, consequently, the profit margin of a commercial trawling vessel is very dependent on the variations in the price of diesel. The share of fuel in the total costs of Portuguese coastal trawlers may be as high as 40%. One way of reducing consumption is to decrease the overall drag resistance of the trawl by introducing changes to...
Portuguese fisheries in seamounts of Madeira-Tore (NE Atlantic)
Campos, Aida; Lopes, Paulo; Fonseca, Paulo; Figueiredo, I.; Henriques, Victor; Gouveia, N.; Delgado, J.; Gouveia, L.; Amorim, A.; Araujo, G.; Drago, T.The activity of the Portuguese fishing fleet operating near seamounts of the Madeira Tore geologic complex was analyzed. The main objective is to identify the different fisheries taking place in the area, characterize the spatial patterns of vessels activity and estimate the fishing intensity, thus contributing to better inform management decisions. Vessel Monitoring System (VMS) and e-logbook data for the peri...
Preliminary results on the use of semi-floating shrimp traps for the striped so...
Eichert, Moritz; Campos, Aida; Fonseca, Paulo; Henriques, Victor; Castro, MargaridaThe present study provides an account of an experimental survey aiming at the evaluation of the catchability of the striped soldier shrimp, Plesionika edwardsii, using semi-floating shrimp traps off the Algarve coast (southern Portugal). Currently, this species is not targeted by the crustacean bottom trawl fleet, and preliminary results on product value suggest that this may become an economically viable new f...
Broad-scale mapping of seafloor habitats in the north-east Atlantic using exist...
Vasquez, Mickaël; Mata Chacón, D.; Tempera, Fernando; O'Keeffe, Eimear; Galparsoro, Ibon; Sanz Alonso, J. L.; Gonçalves, J. M. S.; Bentes, L.If marine management policies and actions are to achieve long-term sustainable use and management of the marine environment and its resources, they need to be informed by data giving the spatial distribution of seafloor habitats over large areas. Broad-scale seafloor habitat mapping is an approachwhich has the benefit of producing maps covering large extents at a reasonable cost. This approach was first investi...
Biomares, a LIFE project to restore and manage the biodiversity of Prof. Luiz S...
Cunha, Alexandra H.; Erzini, Karim; Serrão, Ester A.; Gonçalves, Emanuel João; Borges, Rita Alexandra; Henriques, Miguel; Henriques, VictorThe Marine Park Prof. Luiz Saldanha, in the coast of Arrábida, is the first marine park in continental Portugal. This area is a Nature 2000 site and is considered to be a hotspot for European marine biodiversity. In 2005, the management plan of the park was implemented, ending several habitat menaces, thereby allowing an application to the LIFE—NATURE Programme. The LIFE-BIOMARES project aimed at the restoratio...

Tuberculosis diagnosis after bleach processing for early stage tuberculosis lab...
David, Susana; Sutre, Ana Filipa; Sanca, Armando; Mané, Alfredo; Henriques, Victor; Portugal, Clara; Sancho, Luísa; Cardoso, Ana; Paixão, EleonoraThe diagnosis of tuberculosis is seriously hampered in the absence of standard biosafety laboratory facilities for specimen concentration and Mycobacterium tuberculosis culture. Within a laboratory twinning arrangement, heat-fixed direct smear and sediment from 74 bleach-processed and 20 non-processed specimens from Cumura Hospital, Guinea-Bissau, were sent to Lisbon for molecular evaluation of rifampicin resis...
