Polychaete annelids as live bait in Portugal: harvesting activity in brackish w...
Cabral, S; Alves, AS; Castro, N; Chainho, P; Sá, E; Cancela da Fonseca, L; Fidalgo e Costa, P; Castro, J; Canning-Clode, J; Pombo, A; Costa, JLPolychaete annelids are some of the most heavily harvested invertebrates collected in coastal areas and estuaries for their economic value as live fishing bait or as food supplement in aquaculture activities. However, information on bait digging in Portugal is scarce or incomplete. Thus, the present study aimed at investigating the bait digging activity in the four most relevant brackish water systems in Portug...
Anelídeos poliquetas como isco vivo: caracterização da actividade de apanha em ...
Fidalgo e Costa, P; Sá, E; Alves, AS; Cabral, S; Castro, N; Picard, D; Castro, JJ; Cancela da Fonseca, L; Chainho, P; Canning-Clode, J; Pombo, AMA captura de isco vivo para a pesca, efetuada em sedimentos intertidais, tem aumentado em todo o Mundo, pois face ao incremento da procura, constitui uma importante fonte de rendimento para as populações que vivem junto à costa. Macroinvertebrados, tais como, moluscos, crustáceos e anelídeos poliquetas, entre outros, são capturados em muitos sistemas estuarinos portugueses, sendo a dimensão real das capturas su...
Impact of freshwater inputs on the spatial structure of benthic macroinvertebra...
Félix, PM; Correia, MJ; Chainho, P; Costa, JL; Chaves, ML; Cruz, T; Castro, JJ; Mirra, C; Domingos, I; Silva, ACF; Cancela da Fonseca, LLandlocked lagoons are naturally stressed environments. They are strongly influenced by freshwater input which not only varies naturally, but which is also impacted by anthropogenic activities. This study investigated the direct influence of freshwater discharges on the distribution patterns and abundance of benthic communities in two neighbouring landlocked coastal lagoons, assessing the whole system and the c...
Non-indigenous species in Portuguese coastal areas, coastal lagoons, estuaries ...
Chainho, P; Fernandes, A; Amorim, A; Ávila, SP; Canning-Clode, J; Castro, JJ; Costa, AC; Costa, JL; Cruz, T; Gollasch, S; Grazziotin-Soares, C; Melo, RTrends in abundance, temporal occurrence and spatial distribution of marine and brackish nonindigenous species (NIS) are part of the indicators to assess the compliance of Good Environmental Status in the European Marine Strategy Framework Directive (EU-MSFD). European-wide regional and national databases for NIS will be useful for the implementation of the EU-MSFD but there are still spatial gaps for some regi...

Chainho, P; Félix, PM; Correia, MJ; Fernandes, CM; Costa, JL; Chaves, ML; Stigter, T; Hugman, R; Salvador, N; Costa, L; Domingos, I; Castro, J; Cruz, TNa União Europeia a Directiva Quadro da Água requer a avaliação do estado ecológico de todas as águas interiores (dulciaquícolas e de transição) e costeiras, incluindo os ecossistemas aquáticos superficiais cujo estado ecológico poderá estar dependente do estado das águas subterrâneas (AS). O estado ecológico em lagoas costeiras dependentes de AS depende das interacções AS - água doce superficial - água salgada...
Short-term versus long-term changes in the benthic communities of a small coast...
Félix, PM; Chainho, P; Costa, Jl; Correia, MJ; Chaves, ML; Medeiros, JP; Cabral, HN; Wouters, N; Bernardo, J; Costa, AM; Cristo, M; Silva, G; Azeda, CThe characteristic high variability and low predictability of coastal lagoons, due to strong changes in marine and freshwater inputs, make these ecosystems an interesting casestudy. The small Melides landlocked coastal lagoon in SW Portugal is a paradigmatic example, with a biological community highly stressed by these phenomena. Benthic macroinvertebrate samples were collected in 1998/99 and 2009 and each year...
