Comparative analysis between synthetic vitamin E and natural antioxidant source...
Pereira, Ricardo; Costa, Mónica; Velasco, Cristina; Cunha, Luís M.; Lima, Rui C.; Baião, Luís F.; Batista, Sónia; Marques, Alexandra; Sá, TiagoSynthetic vitamin E is commonly used in aquafeeds to prevent oxidative stress in fish and delay feed and flesh oxidation during storage, but consumers’ preferences tend towards natural antioxidant sources. The potential of vegetable antioxidants-rich coproducts, dried tomato (TO), carrot (CA) and coriander (CO) was compared to that of synthetic vitamin E included in diets at either a regular (CTRL; 100 mg kg−1)...
Physical processing or supplementation of feeds with phytogenic compounds, algi...
Valente, Luisa M.P.; Batista, Sónia; Ribeiro, Catarina; Pereira, Ricardo; Oliveira, Beatriz; Garrido, Inês; Baião, Luís F.; Tulli, FrancesaThis study assessed both the effectiveness of a physical-mechanical rupture method and the ability of feed additives (phytogenic compounds, alginate oligosaccharide and nucleotides) to enhance the utilization of G. gracilis by European seabass. A commercial-based diet was used as control diet (CTRL) and compared with five isoproteic (53.5% Dry matter, DM) and isolipidic (14.9% DM) diets containing 8% of G. grac...
Dimensions for the valorisation of sea urchin (Paracentrotus lividus) gonads pr...
Baião, Luís F.; Moura, Ana Pinto de; Rocha, Célia; Valente, Luísa M. P.; Cunha, Luís MiguelThe main goal of this research was to explore and understand Chefs’ perceptions regarding sea urchin gonads sensorial features, production and use, with an emphasis on echinoculture. This study used a mixed methodology, where three groups of chefs were interviewed: Michelin star, from Ericeira and from Algarve, these being the two main regions of sea urchin consumption. During the interviews, Chefs exposed that...
Seasonal effect in nutritional quality and safety of the wild sea urchin Parace...
Rocha, Filipa; Rocha, A. Cristina; Baião, Luís F.; Gadelha, Juliana; Camacho, Carolina; Carvalho, M. Luísa; Arenas, Francisco; Oliveira, AnaParacentrotus lividus gonads are gastronomic delicacies widely appreciated in Europe. Two commercially exploited populations of sea urchins were characterized, for the first time, in terms of gonad quality (market-related traits such as colour, texture and nutritional value) and safety (contaminants levels) to define the best season for harvesting this valuable resource. Spawning occurred between spring-summer,...
The effect of sex, season and gametogenic cycle on gonad yield, biochemical com...
Rocha, Filipa; Baião, Luís F.; Moutinho, Sara; Reis, Bruno; Oliveira, Ana; Arenas, Francisco; Maia, Margarida R. G.; Fonseca, Antonio J. M.Sea urchin population harvest in the North Atlantic coast of Portugal was characterized in terms of gonad yield, nutritional composition and important market-related traits, over one reproductive cycle (March 2016 to March 2017). Most of the quality attributes showed a seasonal variation strongly dependent on sea urchin sex. Maximum gonad yield (18%) was observed in March 2017. A single spawning event occurred ...
Effect of protein and lipid levels in diets for adult sea urchin Paracentrotus ...
Baião, Luís F.; Rocha, Filipa; Costa, Mónica; Sá, Tiago; Oliveira, Ana; Maia, Margarida R.G.; Fonseca, Antonio J. M.; Pintado, ManuelaParacentrotus lividus gonads are considered a prized seafood delicacy due to its organoleptic features. The increasing market demand for sea urchin depleted several wild stocks, thus aquaculture can play an important role in supplying high-quality animals. Nevertheless, the success of this activity largely depends on the development of nutritionally balanced diets capable of producing excellent gonads. In this ...
