Rumo ao Mar: Avaliação Da Migração De Juvenis De Salmão-do-Atlântico (Salmo sal...
Silva, S.; Alexandre, CM; Honrado, L; Mateus, CS; Quintella, BR; Lança, M.J.; Rato, AS; Oliveira, IC; Oliveira, R; Moreira, A; Almeida, R; Raposo, IO salmão-do-atlântico (Salmo salar L., 1758) é uma espécie piscícola migradora icónica dos ecossistemas aquáticos, com um elevado valor económico e cultural, cuja área de distribuição se localiza desde o mar Báltico até ao norte da Península Ibérica. Em Portugal, as populações de salmão encontram-se no limite sul da sua distribuição e, portanto, em condições sub-ótimas associadas com o regime térmico e variaçõe...
An acclimatization period in a cage promotes site fidelity of hatchery-reared d...
Silva, AF; Castro, JJ; Pereira, E; Marques, JP; Silva, T; Lino, PG; Candeias-Mendes, A; Pousão-Ferreira, P; Pinto, B; Costa, JL; Almeida, PRThe influence of an in-situ acclimatization period of five weeks, seeking the settlement and fidelity of hatchery-reared dusky groupers (Epinephelus marginatus) to the release sites in restocking actions, was tested using acoustic biotelemetry. Eight tagged adult groupers were submitted to the wild conditions in a fish farm cage, while seven remained in the hatchery and tagging location until they were all rele...
Setting Performance Indicators for Coastal Marine Protected Areas: An Expert-Ba...
Cardoso-Andrade, M; Queiroga, H; Rangel, M; Sousa, I; Belackova, A; Bentes, L; Oliveira, F; Monteiro, P; Sales Henriques, N; Afonso, CML; Silva, AFMarine Protected Areas (MPAs) require effective indicators to assess their performance, in compliance with the goals of relevant national and international commitments. Achieving and prioritizing shortlists of multidisciplinary indicators demands a significant effort from specialists to depict the multiple conservation and socioeconomic interests, and the large complexity of natural systems. The present paper d...

Effects of flow regulation on the movement patterns and habitat use of a potamo...
Alexandre, CM; Almeida, Pedro R; Neves, T; Mateus, C; Costa, JL; Quintella, BRRiver regulation for hydroelectricity production results in rapid changes of flow and habitat features, but its effects in the movement patterns of freshwater fish are not well understood. Radiotelemetry was used to track Iberian barbel during a year cycle in non-regulated and regulated rivers. We applied a kernel density method to estimate and compare home range sizes of the two populations. Seasonal patterns ...
Can mitochondrial malondialdehyde content be a useful tool to evaluate sea lamp...
Candeias, Marta; Alves-Pereira, I; Lança, MJ; Ferreira, AF; Quintella, BR; Almeida, PR; Ferreira, RThe sea lamprey is an anadromous species that migrates twice during its life cycle between freshwater and seawater. Microphagous larvae generally spend 4–5 years burrowed in the substrate of rivers and streams before undergoing metamorphosis that ends with the beginning of the juvenile trophic migration. Once metamorphosis is complete, sea lamprey juvenile downstream migrants are fully tolerant to seawater sali...

Hepatic mitochondrial content in malondialdehyde may be a marker of sea lamprey...
Candeias, M; Alves-Pereira, I; Lança, MJ; Ferreira, AF; Quintella, BR; Almeida, PR; Ferreira, RThe atrazine attracts special attention as pollutant because of itspersistence in the aquatic environment. Although this herbicide has been studied in teleost, its toxicity in the sea lamprey, Petromyzon marinus is still poorly understood. Oxidative stress may occur if chemical pollutants contribute to block the capacity of mitochondria to generate ATP with continuous production of reactive oxygen species (ROS)...
