Taurine modulates protein turnover in several tissues of meagre juveniles
Matias, Ana Catarina; Dias, Jorge; Barata, Marisa; Araujo, Ravi Luna; Bragança, José; Pousao-Ferreira, PedroThis study aimed to evaluate the modulatory effect of dietary taurine supplementation on protein turnover of meagre juveniles fed semi-purified plant-based diets. For that purpose, fish (3.2 +/- 0.2 g) were fed with five isoproteic (61.2%), isolipidic (16.6%) and isoenergetic (21.9 kJ g(-1)) experimental diets supplemented with 0.5% (Tau0.5), 1% (Tau1), 1.5% (Tau1.5) and 2% (Tau2) taurine or not (Tau0) for 38 d...
Does consistent individual variability in pelagic fish larval behaviour affect ...
Baptista, Vânia; Costa, Eudriano; Carere, Claudio; Morais, Pedro; Cruz, Joana; Cerveira, Inês; Castanho, Sara; Ribeiro, Laura; Pousao-Ferreira, PedroIndividual animals across all taxa differ consistently in behaviour, i.e. they show personality traits. This inter-individual variability has significant ecological and evolutionary consequences, since it affects a range of population-level processes. Here, we focus on the selection and recruitment of nursery habitats in temperate fish larvae. The "Sense Acuity and Behavioural Hypothesis" has proposed that fish...
Reduction of skeletal anomalies in meagre (Argyrosomus regius, Asso, 1801) thro...
Martins, Gil; Ribeiro, Laura; Candeias-Mendes, Ana; Diogo, Patricia; Gamboa, Margarida; Barata, Marisa; Leonor Cancela, M.; Pousao-Ferreira, PedroThe consolidation of meagre (Argyrosomus regius) in aquaculture requires an understanding and optimization of larval rearing and nutritional conditions. The aim of this study was to analyse the effects of an early introduction of inert diets during larval rearing, on growth performance, digestive enzymes activity and development of skeletal anomalies. This study evaluated the effects of three different timings ...
The irrigation salinity and harvesting affect the growth, chemical profile and ...
Rodrigues, Maria Joao; Monteiro, Ivo; Placines, Chloé; Castañeda-Loaiza, Viana; Slusarczyk, Sylwester; Matkowski, Adam; Pereira, CatarinaPreviously, our group identified the halophyte Polygonum maritimum L. (sea knotgrass) as a promising source of ingredients for the cosmetic, food, pharmaceutical and veterinarian industries. To further explore this species, and to guarantee the supply of biomass for commercial purposes, it is necessary to ensure its sustainable production while assuring the preservation of its chemical and biological properties...
Effects of different slipping methods on the mortality of sardine, Sardina pilc...
Marçalo, Ana; Guerreiro, Pedro; Bentes, Luis; Rangel, Mafalda; Monteiro, Pedro; Oliveira, Frederico; Afonso, Carlos; Pousao-Ferreira, PedroThe effects of two different slipping methods on the survival, physical and physiological response of sardines, Sardina pilchardus, captured in a purse-seine fishery were investigated in southern Portugal. Sardines were collected and transferred into holding tanks onboard a commercial fishing vessel after being captured, crowded and deliberately released using two slipping procedures: standard and modified. The...
Fatty acid profiles of the main lipid classes of green seaweeds from fish pond ...
Cardoso, Carlos; Ripol, Andrea; Afonso, Claudia; Freire, Margarida; Varela, João; Quental-Ferreira, Hugo; Pousao-Ferreira, Pedro; Bandarra, NarcisaThe lipid composition of five species of green seaweeds (Chaetomorpha linum, Rhizoclonium riparium, Ulva intestinalis, Ulva lactuca, and Ulva prolifera) grown in fish pond aquaculture systems was studied. In particular, the overall fatty acid (FA) profile and the FA profile of each main lipid class found in these seaweed species were thoroughly analyzed. It was found that every seaweed had a specific FA profile...
