Sea warming affects bream (Sparus aurata) tissues and stress proteins (HSP70)
Madeira, D.; Vinagre, R.; Costa, Pedro M.; Caeiro, Sandra; Galésio, M.; Santos, H. M.; Nunez, C.; Oliveira, E.; Castro, L.; Pere, I.; Lodeiro, C.The aim of the present study is to assess the stress response of a marine fish, sea bream (Sparus aurata) exposed to increasing water temperature and different water acidity (alone or in combination). Here we present preliminary data on temperature effects on S. aurata at a cellular and molecular level. In addition, tissue samples from muscle, livers, gills and intestine are examined to evaluate any alterations...
Histological biomarkers in liver and gills of juvenile Solea senegalensis exposed
Costa, Pedro M.; Diniz, Mário S.; Caeiro, Sandra; Lobo, Jorge; Martins, Marta; Ferreira, Ana M.; Caetano, Miguel; Vale, Carlos; DelValls, ÁngelYoung juvenile Solea senegalensis were exposed to three sediments with distinct contamination profiles collected from a Portuguese estuary subjected to anthropogenic sources of contamination (the Sado estuary, western Portugal). Sedimentswere surveyed formetals (cadmium, chromium, copper, nickel, lead and zinc), ametalloid (arsenic) and organic contaminants (polycyclic aromatic hydrocarbons, polychlorinated bip...
Biochemical endpoints on juvenile Solea senegalensis exposed
Costa, Pedro M.; Caeiro, Sandra; Diniz, Mário S.; Lobo, Jorge; Martins, Marta; Ferreira, Ana M.; Caetano, Miguel; Vale, Carlos; DelValls, ÁngelJuvenile Solea senegalensis were exposed to fresh sediments from three stations of the Sado estuary (Portugal) in 28-day laboratory assays. Sediments revealed distinct levels of total organic matter, fine fraction, redox potential, trace elements (arsenic, cadmium, chromium, copper, nickel, lead and zinc) and organic contaminants (polycyclic aromatic hydrocarbons, polychlorinated biphenyls and a pesticide: dich...
