This study aimed to investigate the interactive effects between selenium and vitamin B6 supplementation in transsulfuration pathway glutathione metabolism of juvenile rainbow trout (Oncorhynchus mykiss) response oxidative stress. Four plant protein-based diets (48% crude protein 23% total lipid) naturally low were designed: CTL, without any or supplementation; SEL, supplemented with 4 mg per kg diet supplied as selenomethionine (SeMet); PYR, 50 pyridoxine hydrochloride (PN.HCL) SEPY,...
Abstract Arachidonic acid (C20: 4n-6, AA) plays a fundamental role in fish physiology, influencing growth, survival and stress resistance. However, imbalances dietary AA can have detrimental effects on health performance. Optimal requirements for rainbow trout not been established. This study aimed to elucidate the of varying levels survival, long-chain polyunsaturated fatty (LC-PUFA) biosynthetic capacity, oxylipin profiles, lipid peroxidation, resistance fry. Over period eight weeks, 4000...
Abstract Filamentous fungi are able to damage and even destroy archival library materials. Nowadays the conventional method for detecting such micro‐organisms is put them in cultures but methods laborious time‐consuming. ATP methodology has been widely applied other domains its success on bacteria yeast demonstrated. Several commercial reagent kits available they did not give satisfactory results spores mould. We have elaborated new extraction strategies specific fungi. A comparison of 42...
The present study investigated the effect of low stocking density on growth, survival, feed parameters and physiological responses (blood metabolites, welfare indicators, immune biomarkers, transcriptomic stress immune-related genes) juvenile rainbow trout (Oncorhynchus mykiss) reared under a recirculating aquaculture system during 12 weeks. Fish (average weight 29.64 g) were in triplicate four initial densities: nine fish per tank (D9, 3.76 ± 0.06 kg/m3), 18 (D18, 7.66 0.18 27 (D27, 9.67...
Sense of smell is mediated by diverse families olfactory sensing receptors, conveying important dietary information, fundamental for growth and survival. The aim this study was to elucidate the role sensory pathways in regulation feeding behavior carnivorous rainbow trout (RT, Oncorhynchus mykiss), from first until 8 months. Compared a commercial diet, RT fed with total plant-based diet showed drastically altered performance associated feed intake an early stage. Exhaustive examination...
Amino acid (AA) transporters (AAT) control AA cellular fluxes across membranes, contributing to maintain homeostasis. In this study, we took advantage of rainbow trout metabolic feature, which highly relies on dietary AA, explore the and physiological consequences unbalanced diets AAT dysregulations with a particular focus cationic AAs (CAA), frequently underrepresented in plant-based diets. Results evidenced that 24 different CAAT are expressed various tissues, part being subjected AA-...
Selenium is an essential micronutrient and its metabolism closely linked to the methionine cycle transsulfuration pathway. The present study evaluated effect of two different selenium supplements in diet rainbow trout (Onchorhynchus mykiss) broodstock on one-carbon hepatic DNA methylation pattern progeny. Offspring three parental groups trout, fed either a control (NC, basal Se level: 0.3 mg/kg) or supplemented with sodium selenite (SS, 0.8 mg Se/kg) hydroxy-selenomethionine (SO, 0.7 Se/kg),...
It is now recognized that parental diets could highly affect offspring metabolism and growth. Studies in fish are, however, lacking. In particular, the effect of a diet high carbohydrate (HC) low protein (LP) on progeny has never been examined higher trophic level teleost fish. Thus, two-year old male female rainbow trout (Oncorhynchus mykiss) were fed either control (0% 63.89% protein) or containing 35% 42.96% (HC/LP) for complete reproductive cycle females over 5-month period males....

Methionine is a key factor in modulating the cellular availability of main biological methyl donor S-adenosylmethionine (SAM), which required for all methylation reactions including DNA and histone methylation. As such, it represents potential critical nutritional programming. Here, we investigated whether early methionine restriction at first feeding could have long-term programmed metabolic consequences rainbow trout. For this purpose, trout fry were fed with either control diet (C) or...
