Limestone Processing Sludge: From Waste to Sustainable Resource
Guedes, Mafalda; Carrasqueira, Joana; Seixas, Tomás; Afonso, Clélia; Gil, Maria Manuel; Bernardino, Raul; Gamboa, Roberto; Bernardino, SusanaThe limestone quarrying and processing industry generates huge amounts of waste, with limestone sludge being one of the most prevalent and challenging by-products. This study aims to evaluate the potential of limestone sludge as a sustainable secondary raw material for the mechanochemical synthesis of bioceramics, specifically hydroxyapatite (HA), for high-added-value applications in bone tissue engineering. Hi...
Consumer's perceptions and motivations on the consumption of fortified foods an...
Silva, Frederica; Pereira, Tatiana; Mendes, Susana; Gordo, Leonel; Gil, Maria ManuelConsumer attitudes and acceptance of emerging technologies in the food sector, as well as their application, are determining factors for their successful implementation. In this study, a survey was conducted in order to better know and understand the perception, motivation and consumption associated with fortified foods and 3DPF (3-Dimensional Printing Food). Key points such as food neophobia and factors involv...
Increasing biological knowledge for better management of by-catch species: Age,...
Sequeira, Vera; Sousa, Inês; Neves, Ana; Vieira, Ana Rita; Silva, Elisabete; Silva, Frederica; Duarte, Ana Marta; Mendes, Susana; Ganhão, RuiGurnards are a valuable by-catch of mixed demersal fisheries and are commercially important in European waters, but they are often discarded, reported under “mixed gurnards” and with incomplete biological information by species. In the present work, a total of 558 piper gurnard specimens of between 10.9 and 44.4 cm (1 to 11 years) and 425 red gurnard specimens of between 10.2 and 42.1 cm (0 to 9 years) from the...

Annual variations in the mineral element content of five fish species from the ...
Pinto, Filipa R.; Duarte, Ana M.; Silva, Frederica; Barroso, Sónia; Mendes, Susana; Pinto, Edgar; Almeida, Agostinho; Sequeira, Vera; Vieira, Ana RitaThe most consumed fish species in Portugal do not correspond to the most caught fish species on the Portuguese coast. From the point of view of ocean sustainability and economics, it is important to study unexploited or underexploited fish species that have the potential to be introduced into the food market. This potential can be reflected by their nutritional value, where mineral elements are often overlooked...
Temporal changes in sex-specific color attributes and carotenoid concentration ...
Lourenço, Sílvia; Raposo, Andreia; Cunha, Beatriz; Pinheiro, Joaquina; Santos, Pedro M.; Gomes, Ana; Ferreira, Susana; Gil, Maria Manuel; Costa, José L.The market value of sea urchin roe (female and male gonads) depends on several quality criteria, such as size, color, texture, and flavor. Sea urchins given dry pellet feed often produce large gonads, but the preferred bright orange color has been difficult to achieve without the inclusion of supplementary dietary carotenoids. Gonad color depends on carotenoid concentrations (CC), and is influenced by several f...
Modelling fish growth with imperfect data: The case of Trachurus picturatus
Neves, Ana; Vieira, Ana Rita; Sequeira, Vera; Silva, Elisabete; Silva, Frederica; Duarte, Ana Marta; Mendes, Susana; Ganhão, Rui; Assis, CarlosGrowth modelling is essential to inform fisheries management but is often hampered by sampling biases and imperfect data. Additional methods such as interpolating data through backcalculation may be used to account for sampling bias but are often complex and time-consuming. Here, we present an approach to improve plausibility in growth estimates when small individuals are under-sampled, based on Bayesian fittin...
Seasonal study of the nutritional composition of unexploited and low commercial...
Duarte, Ana M.; Silva, Frederica; Mendes, Susana; Pinto, Filipa R.; Barroso, Sónia; Silva, Elisabete; Neves, Ana; Sequeira, Vera; Magalhães, MariaTarget species diversification is essential for fisheries sustainability and fish market revitalization. Fish discards are a widely recognized problem resulting from fisheries worldwide, and are of major concern for all sector players, from administrations, to fishermen, and scientists. However, non-target species are seldom studied, and information on nutritional profiles and seasonal changes in nutritional pr...
