Strategy combining mammalian fats with supplementation of pungent spices in aqu...
Ruiz, Alberto; Gisbert, Enric; Estevez, Alicia; Reyes-López, Felipe E.; Vallejos-Vidal, Eva; Tort, Lluís; Dias, Jorge; Engrola, Sofia; Magalhães, SaraThe replacement of fish oil (FO) in aquafeeds usually leads to imbalances in the dietary content of n-3 and n-6 polyunsaturated fatty acids (PUFA), with negative consequences for fish performance, health, and fillet quality. Animal-rendered fats are an alternative lipid source high in saturated fatty acids, potentially sparing n-3 PUFA from oxidation, and with lower n-6 PUFA contents than plant-based oils, espe...
Thermal imprinting modifies adult stress and innate immune responsiveness in th...
Mateus, Ana; A Costa, Rita; Cardoso, João CR; Andree, Karl B.; Estevez, Alicia; Gisbert, Enric; Power, DeborahThe impact of thermal imprinting on the plasticity of the hypothalamic-pituitary-interrenal (HPI) axis and stress response in an adult ectotherm, the gilthead sea bream (Sparus aurata, L.), during its development was assessed. Fish were reared under 4 thermal regimes, and the resulting adults exposed to acute confinement stress and plasma cortisol levels and genes of the HPI axis were monitored. Changes in immu...
Thermal imprinting modifies bone homeostasis in cold-challenged sea bream (Spar...
Mateus, Ana; Costa, Rita; Gisbert, Enric; PI Pinto, PPinto; Andree, Karl B.; Estevez, Alicia; Power, DeborahFish are ectotherms and temperature plays a determinant role in their physiology, biology and ecology, and is a driver of seasonal responses. The present study assessed how thermal imprinting during embryonic and larval stages modified the response of adult fish to low water temperature. We targeted the gilthead sea bream, which develops a condition known as winter syndrome when it is exposed to low water tempe...
New developments and biological insights into the farming of Solea senegalensis...
Morais, Sofia; Aragão, C.; Cabrita, Elsa; Conceição, L. E. C.; Constenla, Maria; Costas, Benjamín; Dias, Jorge; Duncan, Neil; Engrola, S.Senegalese sole was one of the earliest identified candidate species with high potential for aquaculture diversification in the south of Europe. Its culture has been possible, and commercially attempted, for several decades, but intensive production has been slow to take off. This has been explained mostly by serious disease problems, high mortality at weaning, variable growth and poor juvenile quality. However...
Coordinated regulation of chromatophore differentiation and melanogenesis durin...
Darias, Maria J.; Andree, Karl B.; Boglino, Anais; Fernandez, Ignacio; Estevez, Alicia; Gisbert, EnricAbnormal pigmentation of Senegalese sole has been described as one problem facing the full exploitation of its commercial production. To improve our understanding of flatfish pigmentation of this commercially important species we have evaluated eleven genes related to two different processes of pigmentation: melanophore differentiation, and melanin production. The temporal distribution of gene expression peaks ...
