Abstract With demands and reliance on aquaculture still growing, there are various challenges to allow sustainable growth the shift from fishmeal (FM) other protein sources in aquafeed formulations is one of most important. In this regard, interest use insect meal (IM) aquafeeds has grown rapidly. Accordingly, aim present study was assess effects dietary IM Hermetia illucens (Hi) larvae included a low-FM diet gut microbial communities rainbow trout ( Oncorhynchus mykiss ), terms both...
Abstract Background Aquaculture must continue to reduce dependence on fishmeal (FM) and fishoil in feeds ensure sustainable sector growth. Therefore, the use of novel aquaculture feed ingredients is growing. In this regard, insects can represent a new world protein-rich for farmed fish feeds. Accordingly, we investigated effects full replacement FM with Tenebrio molitor (TM) larvae meal diet rainbow trout ( Oncorhynchus mykiss ) gut skin microbiota. Methods A feeding trial was conducted 126...
The present research tested the effects of dietary nisin-producing Lactococcus lactis on growth performance, feed utilization, intestinal morphology, transcriptional response, and microbiota in gilthead sea bream ( Sparus aurata ). A feeding trial was conducted with fish weighting 70–90 g. Fish were tagged passive, integrated transponders distributed nine 500 L tanks 40 each. fed for 12 weeks either a control (diet A) or experimental diets (diets B C) triplicate (3 tanks/diet). Extruded...
The significant microbiota variability represents a key feature that makes the full comprehension of functional interaction between and host an ongoing challenge. To overcome this limitation, in study, fish intestinal was analyzed through meta-analysis, identifying core constructing stochastic Bayesian network (BN) models with SAMBA. We combined three experiments performed gilthead sea bream juveniles same hatchery batch, reared at season/location, fed diets enriched on processed animal...
The search for new alternatives the revalorization of porcine blood is crucial due to large quantities that are annually generated in slaughterhouses. In this study, a sequential enzymatic hydrolysis pig was optimized using different combinations enzymes, namely, Alcalase 4.0 L and Protana™ Prime, Flavourzyme 1000 L, Protamex®, as sustainable method obtaining extracts rich bioactive peptides. All assayed hydrolysates exhibited peptide profiles showed vitro antioxidant, hypoglycemic,...
The development of sustainable aquaculture relies on replacing marine raw materials like fish meal (FM) and oil (FO). Emerging alternatives, such as single-cell proteins alternative lipids, offer promise. This study explored the effects partially substituting FM with 10% bacterial protein (Methylococcus capsulatus) completely FO a blend poultry (PO) DHA-rich microalgae in European sea bass (Dicentrarchus labrax) unselected (WT) selected (HG) genotypes. results indicated that had no adverse...
In the present study, gilthead sea bream (Sparus aurata) was reared using sustainable feeds containing insect meal from Hermetia illucens larvae. Proteomics and proton nuclear magnetic resonance-based metabolomics analysis were used to assess metabolic impact of tested in liver, whereas composition muscle fillets characterized by means gas chromatography fatty acid methyl esters. Including 10% while correspondingly reducing fish did not substantially alter metabolism dietary nutrients,...
Gut microbiomes of fish species consist thousands bacterial taxa that interact among each other, their environment, and the host. These complex networks interactions are regulated by a diverse range factors, yet little is known about hierarchy these interactions. Here, we introduce SAMBA (Structure-Learning Aquaculture Microbiomes using Bayesian Approach), computational tool uses unified network approach to model structure gut with biotic abiotic variables associated typical aquaculture...
The influence of hydration on the Watson−Crick cytosine−guanine base pair was investigated, testing ability self-consistent field for molecular interaction (SCF-MI) ab initio method to reproduce pattern present in a real system (the DNA framework). positions sites around predicted by knowledge-based approach employing crystallographic data were compared optimized structures. SCF-MI applied perform basis set superposition error (BSSE)-free geometry optimization. shell taken into...
The sustainable development of modern aquaculture must rely on a significant reduction the fish meal (FM) used in aquafeed formulations. However, FM substitution with alternative ingredients diets for carnivorous species often showed reduced nutrient absorption, significantly perturbed metabolisms, and histological changes at both hepatic intestinal levels. In present study, rainbow trout ( Oncorhynchus mykiss ) were fed three different experimental aquafeeds. A control diet higher content...
Alternative nutrient sources to fishmeal for fish feed, such as insect meals, represent a promising sustainable supply. However, the consequences digestive function have not been exhaustively investigated. In present study we evaluated effect of partial substitution with 10% Hermetia illucens (Hi10) larvae meal on neuromuscular proximal and distal intestine in gilthead sea bream. animals fed meal, weight growth parameters were similar controls conventional fishmeal. addition, no anomalies...
The structure and energy of the guanine (G)−adenine (A) base pairs in G(anti)−A(anti) G(anti)−A(syn) conformations as well their complexes with hydrated zinc(II) ions have been investigated by self-consistent field for molecular interaction (SCF-MI) ab initio method. formation covalent bonds between Zn(II) N7 sites bases results an increase binding G−A pairs. In addition, SCF-MI calculations also performed (G)−guanine (G)−cytosine (C) (G−GC) triplet its complex a ion bound to site...
Using a circular economy concept, the present study investigated use of crude glycerol, primary by-product biodiesel production, as low-priced nutrient source for heterotrophic cultivation fungus-like protist Schizochytrium limacinum SR21 strain. The whole biomass this oleaginous microorganism, rich in docosahexaenoic acid (DHA) and high-quality proteins, was then paired with vegetable oil (VO) used to replace fish (FO) European sea bass ( Dicentrarchus labrax ) feeds. Four nutritionally...

A confinement stress test with 75% tank space reduction and behavioural monitoring through tri-axial accelerometers externally attached to the operculum was designed. This procedure validated by demonstrating less pronounced response in gilthead sea bream than European bass (950-1200 g). Our study aimed assess habituation high stocking densities such bream. Animals (420-450 g) were reared (June-August) a flow-through system at two (CTRL: 10-15 kg/m
Oxford Nanopore Technology (ONT) allows for the rapid profiling of aquaculture microbiomes. However, not all experimental and downstream methodological possibilities have been benchmarked. Here, we aimed to offer novel insights into use different library preparation methods (standard-RAP native barcoding-LIG), primers (V3-V4, V1-V3, V1-V9), basecalling models (fast-FAST, high-HAC, super-accuracy-SUP) implemented in ONT elucidate microbiota associated with aquatic environment farmed fish,...
