In recent years, the pursuit of sustainable aquaculture practices has focused on alternatives to fisheries-derived ingredients, avoid economic and environmental unsustainability. Low-trophic organisms, such as polychaetes, could be a suitable alternative fishmeal due their high protein content. This study aimed investigate feasibility replacing with polychaete meal (Alitta virens; PM) in diets for European seabass (Dicentrarchus labrax; Wi, ~14.5 g). Four isoproteic (51% dry matter, DM)...
The effects of black soldier fly ( Hermetia illucens ) meal (HM) on gut morphology, microbial community, and humoral immune response was evaluated in meagre Argyrosomus regius juveniles. For that purpose, fish with 18.0±0.02 g were fed a control diet (CTR) without HM, 3 other diets including 10, 20 30% HM (diets HM10, HM20 HM30, respectively), replacing 17, 35 52% (FM), for 9 weeks. distal intestine (DI) showed no significant histomorphologic alterations fold height, lamina propria,...
The disruption of pathogen communication or quorum-sensing (QS) via quorum-quenching (QQ) molecules has been proposed as a promising strategy to fight bacterial infections. Bacillus spp. have recognizable biotechnology applications, namely probiotic health-promoting agents source natural antimicrobial molecules, including QQ molecules. This study characterized the potential 200 spp., isolated from gut different aquaculture fish species, suppress pathogens QS. Approximately 12% tested...
Insect meal (IM), recently authorized for use in aquafeeds, positions itself as a promising commodity aquafeed inclusion. However, insects are also rich chitin, structural polysaccharide present the exoskeleton, which is not digested by fish, resulting lower fish performance. Through application of dietary pressure, this study aimed to modulate European sea bass gut microbiota towards enrichment chitinolytic bacteria allow isolation novel probiotics capable improving IM-containing diets,...
Selenium (Se) is a crucial trace mineral in human nutrition, known for its various health benefits, including the enhancement of antioxidant defenses. Enrichment fish fillets with Se seen as an interesting strategy to reduce risk deficiency diets. While inorganic sources have been traditionally used supplement diets, organic forms demonstrated superior bioavailability and efficacy managing oxidative stress tissue retention rates compared their counterparts. The main objective this study was...
Marine algae are recognised sources of bioactive compounds that have attracted great interest as nutritional supplements for aquaculture fish. Intensive rearing conditions often expose fish to husbandry-related stressors, rendering more susceptible disease and reducing production yields. The present work evaluated the potential two marine extracts (Fucus vesiculosus Nannochloropsis gaditana) mitigate stress effects in meagre (Argyrosomus regius) exposed an acute handling (AS). A plant-based...
Insect meals (IM) are being pointed out as a promising sustainable protein source. However, chitin in IM may negatively interfere with fish performance and nutrient availability. Given that carnivorous have low or inexistent ability to digest chitin, novel strategies needed overcome chitin-imposed bottlenecks. Carbohydrolytic sporeforming probiotics offer competitive industrial approach, able resist the harsh feed manufacturing process, transport, storage, animal's gastrointestinal tract,...
Recent research has revealed the significant impact of novel feed ingredients on fish gut microbiota, affecting both immune status and digestive performance. As a result, analyzing microbiota modulatory capabilities may be useful method for assessing potential functionality ingredients. Therefore, this study aimed to evaluate effects dietary polychaete meal (PM) from Alitta virens autochthonous allochthonous European seabass ( Dicentrarchus labrax ). Two diets were compared: control diet...
Various combinations of alternative marine lipid sources were evaluated for their potential to replace commercially available fish oil, specifically sardine oil (SO), in turbot (Scophthalmus maximus). A based diet was used as a control (CTRL) containing (7.0%) and rapeseed (RO; 3.8%) the main sources, providing 1.9% EPA + DHA. positive (SARDINE) also included, which SO sole source provide 2.6% Two other diets formulated target approximately same levels DHA control: ALGA (2.7% algae 5.4% SO,...
The search for natural immunotherapeutic agents has become increasingly important fish disease treatment and prophylaxis. present research explored the effects of macro- microalgal extracts on zebrafish juvenile growth immune status. A plant-based diet was used as a control (diet C), seven other diets were prepared similar to C, supplemented with 10 g Kg−1 each algal extract (Fucus vesiculosus, F; Nannochloropsis gaditana, N; Ulva rigida, U), or combination (diets FN, FU, NU FNU)....

Meagre (Argyrosomus regius) belongs to the family Sciaenidae and is a promising candidate for Mediterranean aquaculture diversification. As relatively recent species in aquaculture, physiological consequences of immune system activation meagre are understudied. Spleen, as primary lymphoid organ has an essential role inflammatory responses. In this study, we have evaluated vivo effects lipopolysaccharide (LPS) on spleen transcriptome by RNA-seq analysis at 4 24 h after injection.
