Effect of diets with different non-starch polysaccharides profiles on gilthead ...
Guttuso, P.; Santos, R. A.; Pousão-Ferreira, P.; Carvalho, N. M. de; Madureira, A. R.; Serra, C. R.; Oliva-Teles, A.; Guerreiro, I.Plant feedstuffs are the most established alternative to fish meal in the feed industry but although being readily available and economically viable, the presence of non-starch polysaccharides (NSPs) might impair their use. Accounting the NSP profile of plant feedstuffs, a gilthead seabream (Sparus aurata) growth trial was run testing five isolipidic and isoproteic plant feedstuffs-based diets with 30% inclusio...
Movements of hatchery-reared dusky groupers released in a Northeast Atlantic Co...
Silva, A.F.; Horta e Costa, B.; Costa, J.L.; Pereira, E.; Marques, J.P.; Castro, J.J.; Lino, P.G.; Candeias-Mendes, A.; Pousão-Ferreira, P.; Sousa, I.No-take areas are key instruments to promote the effectiveness of Marine Protected Areas (MPAs), particularly concerning the protection of endangered species such as the dusky grouper (Epinephelus marginatus). However, despite the establishment of no-take areas and the prohibition of catching this species in a southwestern Portuguese MPA (SACVMP—‘Sudoeste Alentejano’ and ‘Costa Vicentina’ Marine Park) since 201...
Lipid composition and some bioactivities of 3 newly isolated microalgae (Tetras...
Cardoso, Cátia; Pereira, H.; Franca, J.; Matos, J.; Monteiro, I.; Pousão-Ferreira, P.; Gomes, A.; Barreira, Luísa; Varela, Varela J.; Neng, N.Recently isolated microalgae Tetraselmis sp. IMP3, Tetraselmis sp. CTP4, and Skeletonema sp. were studied. The three novel strains contained relatively high levels of polyunsaturated fatty acids (PUFA) and n3 PUFA. However, highly unsaturated n3 FA contents were relatively low (5.7-13.0% of the total FA). In general, eicosapentaenoic acid (EPA, 20:5 n3) contents were low (< 6.4% of the total FA). However, in Sk...
Swimming abilities of temperate pelagic fish larvae prove that they may control...
Baptista, Vânia; Morais, Pedro; Cruz, Joana; Castanho, Sara; Ribeiro, L.; Pousão-Ferreira, P.; Leitão, Francisco Miguel de Sousa; Wolanski, E.The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities and sensorial acuity of temperate fish larvae allows them to find and swim towards coastal nursery areas, which are crucial for their recruitment. To gather further evidence to support this theory, it is necessary to understand how horizontal swimming capability varies along fish larvae ontogeny. Therefore, we studied the ...
Composition and bioaccessibility of elements in green seaweeds from fish pond a...
Afonso, C.; Cardoso, C,; Ripol, A.; Varela, J.; Quental-Ferreira, H.; Pousão-Ferreira, P.; Ventura, M.S.; Delgado, I.M.; Coelho, I.; Castanheira, I.The elemental composition of five species of green seaweeds (Chaetomorpha linum, Rhizoclonium riparium, Ulva intestinalis, Ulva lactuca, Ulva prolifera) grown in fish pond aquaculture systems were studied. The elemental bioaccessibility in these species was also investigated through the application of an innovative in vitro digestive model of the human gastrointestinal tract. It was observed that R. riparium ha...
CONSERVAÇÃO EM REFRIGERADO DE FIAMBRES DE CORVINA E DOURADA EMBALADOS EM ATMOSF...
Patriarca, J.; Ribeiro, A.T.; Silva, H.; Vieira, H.; Teixeira, B.; Rodrigues, M.J.; Gil, M.; Pousão-Ferreira, P.; Mendes, R.The search for healthier food products has increased the development of novel fish-based functional foods. In the present work the quality changes during refrigerated storage of meagre and sea bream hams enriched with dietetic fibers and packaged in modified atmosphere (30 % CO2 / 70 % N2) were evaluated. The fish hams had a good sensory acceptance and in microbiological terms were acceptable until at least 20 ...
Solea senegalensis vasa transcripts: molecular characterisation, tissue distrib...
Pacchiarini, T.; Cross, I.; Leite, Ricardo; Gavaia, Paulo J.; Ortiz-Delgado, J. B.; Pousão-Ferreira, P.; Rebordinos, L.; Sarasquete, C.; Cabrita, ElsaThe Vasa protein is an RNA helicase belonging the DEAD (Asp-Glu-Ala-Asp)-box family. The crucial role played by the vasa gene in the germ-cell lineage of both vertebrates and invertebrates has made this gene a useful molecular marker for germinal cells and a useful tool in surrogate broodstock production using primordial germ cell transplantation. With the aim of establishing a novel approach to improving Solea...
Behavioural responses of sardines Sardina pilchardus to simulated purse-seine c...
Marçalo, A.; Pousão-Ferreira, P.; Pierce, G. J.; Stratoudakis, Y.; Erzini, KarimThe behavioural effects of confinement of sardine Sardina pilchardus in a purse seine were evaluated through three laboratory experiments simulating the final stages of purse seining; the process of slipping (deliberately allowing fishes to escape) and subsequent exposure to potential predators. Effects of holding time (the time S. pilchardus were held or entangled in the simulation apparatus) and S. pilchardus...
Larval and juvenile development of dusky grouper Epinephelus marginatus reared ...
Cunha, M. E.; Re, P.; Quental-Ferreira, H.; Gavaia, Paulo J.; Pousão-Ferreira, P.The larval development of the dusky grouper Epinephelus marginatus up to the benthic juvenile stage is described in detail to establish a reference for their larval identification. Development is described in terms of ontogenetic changes in morphology, growth, pigmentation, fin structure and skeletal structure. Larvae were reared in mesocosms at a mean temperature of 24·3◦ C, salinity of 36·5, dissolved oxygen ...
