Lidocaine supplementation in clove-oil and 2-phenoxyethanol anesthesia for gilt...
Tchobanov, Carolina F.; Vaz, Mariana; Pires, Damiana; Passos, Ricardo; Antunes, Luís M.; Baptista, TeresaAnimal welfare and reducing stress during procedures are key objectives for success in animal production. Anesthesia has been used for procedures to reduce animal stress and its negative impact on welfare. This study aimed first to refine the concentrations of the anesthetic clove-oil (CO) and lidocaine (L) in gilthead seabream (Sparus aurata) juveniles (56.0 ± 15.09 g) and then combine clove-oil and 2-phenoxye...
Proximate composition and fatty acid profile of Gilthead seabream (Sparus aurat...
Antunes, Madalena; Neves, Marta; Pires, Damiana; Passos, Ricardo; Carmo, Beatriz do; Tchobanov, Carolina F.; Forte, Sara; Vaz, Mariana; Baptista, TeresaSeaweeds are a sustainable source of protein and lipids that may be used to replace fish by-products in aquaculture feed. This study aimed at using the macroalgae Pelvetia canaliculata as an ingredient in gilthead seabream (Sparus aurata) feed, either as freeze-dried powder or as algae residue (waste) that was obtained after the supplementation of sunflower oil. The formulated diets and the fish muscle were ana...

The Neglect of Financial Literacy in Portugal - Until When?
Passos, RicardoThe communication of financial literacy is a very sensitive topic in Portugal. This is an extremely important topic for young people nowadays, but it has been undervalued in our country.With this article, I present my well grounded opinion on the topic, identifying the problems, possible solutions and a final appreciation. Throughout the article it is highlighted the importance of financial literacy and how it ...
Pelvetia canaliculata as an aquafeed supplement for gilthead seabream Sparus au...
Pires, Damiana; Passos, Ricardo; Carmo, Beatriz do; Tchobanov, Carolina F.; Forte, Sara; Vaz, Mariana; Antunes, Madalena; Tecelão, CarlaFor sustainable and economically viable aquaculture, it is necessary to search for alternative sources of aquafeeds. Algae have been studied because of their bioactive compounds with several activities such as antioxidants. The direct incorporation of the macroalgae Pelvetia canaliculata in sunflower oil to increase oxidative stability and biological value results in waste with high nutritional value that may b...
Functional and molecular mmune response of rainbow trout (Oncorhynchus mykiss) ...
Fajardo, Carlos; Santos, Paulo; Passos, Ricardo; Vaz, Mariana; Azeredo, Rita; Machado, Marina; Fernández-Boo, Sergio; Baptista, Teresa; Costas, BenjaminCurrently, aquaculture production of rainbow trout (Oncorhynchus mykiss) is a multibillion dollar industry; nevertheless, the development of this sector has not been exempt from pitfalls related to the recurrent presence of pathogens of bacterial origin. This is the case of Yersinia ruckeri, the etiologic agent of the infectious pathology known as Enteric Red Mouth Disease (ERM), causing serious economic losses...
Early immune modulation in European Seabass (Dicentrarchus labra) juveniles in ...
Vaz, Mariana; Pires, Damiana; Pires, Pedro; Simões, Marco; Pombo, Ana; Santos, Paulo; Carmo, Beatriz do; Passos, Ricardo; Costa, Janina Z.The early host–pathogen interaction between European seabass (Dicentrarchus labrax) and Betanodavirus was examined by using juvenile fish infected intramuscularly with RGNNV (red-spotted grouper nervous necrosis virus). The time course selected for sampling (0–144 h post-infection (hpi)) covered the early stages of infection, with hematological, antioxidant and immunological responses examined. Early activation...
Principais Patógenos que Afetam Peixes Cultivados em Portugal
Pires, Damiana; Vaz, Mariana; Pires, Pedro; Passos, Ricardo; Carmo, Beatriz; Santos, Paulo; Tomás, Mafalda; Ferreira, Susana M. F.; Baptista, TeresaA mortalidade de peixes que ocorre nas explorações aquícolas, devida à ação de agentes patogénicos, constitui ainda um dos maiores entraves ao desenvolvimento económico do sector. Tendo em conta a sua origem, as doenças podem subdividir-se em não infeciosas e infeciosas, sendo estas últimas as de maior importância e a principal causa de perdas económicas elevadas. As doenças infeciosas agrupam-se em três catego...
Modulatory effect of Gracilaria gracilis on European seabass gut microbiota com...
Gonçalves, Ana Teresa; Simões, Marco; Costa, Cátia; Passos, Ricardo; Baptista, TeresaSeaweeds are an important source of nutrients and bioactive compounds and have a high potential as health boosters in aquaculture. This study evaluated the effect of dietary inclusion of Gracilaria gracilis biomass or its extract on the European seabass (Dicentrarchus labrax) gut microbial community. Juvenile fish were fed a commercial-like diet with 2.5% or 5% seaweed biomass or 0.35% seaweed extract for 47 da...
