The decline of the ecosystem services generated by anadromous fish in the Iberi...
Almeida, Pedro R.; Mateus, Catarina Sofia; Alexandre, Carlos M.; Pedro, Sílvia; Boavida-Portugal, Joana; Belo, Ana Filipa; Pereira, EsmeraldaThis work aims to present an historical review of the ecosystem services provided by anadromous fish (i.e., species that migrate from the sea to the river to spawn) throughout Human time, as well as of the main related threats, focusing on the Iberian Peninsula region. Anadromous fish provide important provision, cultural, regulatory and supporting ecosystem services across their distribution range and have bee...
Does largemouth bass (Micropterus salmoides) have a season to be consumed?
Almeida, Marta; Jorge, André; Machado, Maria; Alexandre, Carlos M.; Almeida, Pedro R.; Lança, M.J.Introduced in the second half of the 20th century in Portugal, the largemouth bass (Micropterus salmoides) can currently be found in most of the lakes and reservoirs of Southern Europe, being an invasive species in Portugal and other Mediterranean regions. Increasingly in Portugal, the largemouth bass is one of the most sought-after species for recreational fishing activities and a species with the potential to...
Habitat Suitability of Threespine Stickleback (Gasterosteus aculeatus L.) in th...
Moreia, André; Boavida_Portugal, Joana; Almeida, Pedro R.; Silva, Sara; Alexandre, Carlos M.The conservation of fish biodiversity requires reliable information on their distribution and habitat use, especially of endemic species that generally occur in restricted geographic areas and specific habitats. This is the case of threespine stickleback (G. aculeatus L.), that is a small freshwater fish listed as Endangered (EN) in Portugal, which represents the southern limit of the species global distributio...
Into the Wild: A New Approach to the Aquaculture Production of Brown Trout (Sal...
Domingues, Andreia; Alexandre, Carlos M.; Mateus, Catarina S.; Silva, Sara; Almeida, Pedro R.The brown trout (Salmo trutta L.) is one of the most iconic native species from European river ecosystems and is also one of the main species of interest for recreational fishing activities (e.g., fly fishing). This species has a significant potential to attract anglers and related investment to the main fishing grounds, which are usually located in poorly developed areas and away from main city centers. Due to...
Meso- and Micro-Habitat Preferences of European River and Brook Lamprey in a Me...
Oliveira, Inês; Quintella, Bernardo R.; Mateus, Catarina S.; Alexandre, Carlos M.; Almeida, Pedro R.The European river (Lampetra fluviatilis Linnaeus, 1758) and brook (Lampetra planeri Bloch, 1784) lampreys are considered ‘paired species’, i.e., they are closely related and morphologically very similar but have distinct modes of adult life (anadromous vs. resident). In the Iberian Peninsula, the southern limit of both species’ distribution, they face different pressures (e.g., barriers, pollution, hydrologica...
Genetic Structure and Diversity of Brown Trout (Salmo trutta L.) in Portugal
Pereira, Joana; Silva, Sara; Almeida, Pedro R.; Alexandre, Carlos M.; Almeida, Rita; Domingues, Andreia; Alves, Maria J.; Mateus, Catarina S.Population genetic studies have been extensively used as tools for the management and conservation of salmonid species and related habitats. The brown trout, Salmo trutta (Linnaeus 1758), is one of the most studied species within its family, and is frequently used as a population model. It can have a highly complex and variable life history, often presenting a migratory ecotype (i.e., sea trout), and it is cons...
Acoustic Telemetry Unravels Movements and Habitat Use Patterns of Juvenile Meag...
Marques, João P.; Almeida, Pedro R.; Moreira, Pedro; Reis-Santos, Patrick; Prista, Nuno; Costa, José L.; Domingos, Isabel; Alexandre, Carlos M.The meagre is among the largest Sciaenidae in the world (max: 230 cm, 103 kg), with a wide distribution range encompassing the NE and CE Atlantic Ocean and the Mediterranean Sea. The life cycle in Atlantic waters includes migratory movements from feeding and overwintering areas at sea to spawning and nursery areas in estuaries and coastal waters. However, significant spawning aggregations are only observed in f...
Technologies for the study of hydropeaking impacts on fish populations: Applica...
Alexandre, Carlos M.; Quintella, Bernardo R.; Ovidio, Michaël; Boavida, Isabel; Costa, Maria J.; Palstra, Arjan P.; Lima, Rui L. Pedroso deDam construction and streamflow regulation are increasing throughout the world, with impacts in impounded aquatic ecosystems. Hydropower dams, some of them causing a phenomenon called “hydropeaking” during their operation, are known for having a variety of impacts on downstream aquatic biota, particularly fish, and respective habitat. This can result in significant changes, from the community (e.g., fish assemb...
Temporal patterns of the catadromous thinlip grey mullet migration in freshwater
Pereira, Esmeralda; Quintella, Bernardo R.; Lança, Maria João; Alexandre, Carlos M.; Mateus, Catarina S.; Pedro, Sílvia; Belo, Ana Filipa; Rato, AnaThe thinlip grey mullet (Chelon ramada Risso, 1827) is a catadromous fish that performs massive migrations to freshwater habitats for feeding purposes that can assume a structuring role on riverine ecology due to the biomass involved in these movements. Seasonal movements of thinlip grey mullet through a vertical slot fish pass located in River Mondego (Portugal) were continuously monitored between 2013 and 201...
Fish pass use by shads (Alosa alosa L. and Alosa fallax (Lacépède, 1803)): impl...
Belo, Ana; Cardoso, Gabriela; Pereira, Esmeralda; Quintella, Bernardo; Mateus, Catarina; Alexandre, Carlos M.; Batista, Carlos; Telhado, AnaFish pass monitoring is essential to ensure the device's effectiveness as a mitigation measure for river impoundment, guaranteeing the longitudinal continuity of rivers, which is particularly important for diadromous fish that depend on obligatory migrations to freshwater reproduction (anadromous) or feeding areas (catadromous) to complete their life cycle. The upstream migration of the anadromous allis (Alosa ...
