Fermented agar by-product and sunflower cake mixture as feedstuff for European ...
Ferreira, Marta; Ramos-Oliveira, Catarina; Magalhães, Rui; Martins, Nicole; Ozório, Rodrigo O. A.; Salgado, José Manuel Seara; Belo, IsabelIndustrial agar production from red seaweeds such as Gelidium sp. generates large quantities of byproducts (GBP), often discarded as waste. GBP and sunflower cake (SC) are under-valorized as feedstuff due to their high non-starch polysaccharide (NSP) content. Solid-state fermentation (SSF) may disrupt NSP and improve their nutritional value. This study evaluated the utilization of Aspergillus ibericus and Asper...
Combined effects of temperature and dietary lipid level on body composition, gr...
Cardoso, Patrícia G.; Gonçalves, Odete; Cavalheri, Thais; Amorim, Vânia E.; Cao, Weiwei; Alexandrino, Diogo A. M.; Jia, Zhongjun; Carvalho, Maria F.The effects of increasing temperature and dietary lipid level on the body composition, growth performance, and freshness profile of the European seabass (Dicentrarchus labrax) were evaluated through a fish trial lasting 56 days. Findings demonstrated that fish reared at 24 °C presented a lower lipid level and a higher daily growth index than those reared at 20 °C. On the other hand, the sea bass condition index...
On the Utilization of Dietary Glycerol in Carnivorous Fish - Part I: Insights I...
Viegas, Ivan; Tavares, Ludgero C.; Plagnes-Juan, Elisabeth; Silva, Emanuel; Rito, João; Marandel, Lucie; Palma, Mariana; Ozório, Rodrigo O. A.Glycerol is the by-product of biodiesel production and its utilisation in fish feed has recently gained relevance. As an important metabolic intermediate and structural component of triacylglycerol (TAG), it is still unclear whether its supplementation affects lipid utilisation and/or deposition in different tissues. Accordingly, a set of studies was aimed to evaluate how increasing levels of dietary glycerol (...

Acute Stress and an Electrolyte-Imbalanced Diet, but Not Chronic Hypoxia, Incre...
Magnoni, Leonardo J.; Novais, Sara C.; Eding, Ep; Leguen, Isabelle; Lemos, Marco F. L.; Ozório, Rodrigo O. A.; Geurden, Inge; Prunet, PatrickIn aquaculture, fish may be exposed to sub-optimal rearing conditions, which generate a stress response if full adaptation is not displayed. However, our current knowledge of several coexisting factors that may give rise to a stress response is limited, in particular when both chronic and acute stressors are involved. This study investigated changes in metabolic parameters, oxidative stress and innate immune ma...
Changes in fatty acid profile and chemical composition of meagre (Argyrosomus r...
Simões, Tiago; Fonseca, Sthelio B.; Augusto, Ana; Granada, Luana; Ozório, Rodrigo O. A.; Gonçalves, Jose F. M.; Pascoal, Leonardo A. F.This studyaimed to evaluatechangesin body composition, speciallymuscleandliver fatty acid profileinmeagre (Argyrosomus regius) fed with different dietary lipid sources and levels, with or without selenium supplementation. Six hundred meagre were fed twice a day, 6 days per week, with eight experimental diets for 60 days. Diets were a combination of fish oil or a vegetable blend (45% linseedþ 35% rapeseedþ 20% s...
Olfactory sensitivity to amino acids in the blackspot sea bream (Pagellus bogar...
Hubbard, Peter C.; Barata, Eduardo N.; Ozório, Rodrigo O. A.; Valente, Luisa M. P.; Canário, Adelino V. M.The current study investigated the olfactory sensitivity of the blackspot sea bream to amino acids, odorants associated with food detection in fsh, and compared the efficacy of two different experimental methods: multiunit recording from the olfactory nerve and the electro-olfactogram (EOG). Twenty essential amino acids plus L-DOPA evoked clear, concentration-dependent olfactory responses using both methods, wi...
Separate and combined effects of cyclic fasting and l-carnitine supplementation...
Nogueira, Natacha; Cordeiro, Nereida; Canada, Paula; Silva, Paula Cruz e; Ozório, Rodrigo O. A.We examined the e¡ects of cyclic fasting in red porgy (Pagrus pagrus) fed di¡erent dietary carnitine levels. Ju venile ¢sh (23.58 3.49 g) were divided into eight groups ^ four groups were fed every day to apparent sa tiation, while the other four were fasted for 7 days every 2 weeks. In each feeding regime, two replicates were fed an L-carnitine non-supplemented diet (46 mg kg 1 ) and the other two groups were ...
