A 1000-cow study across four European countries was undertaken to understand what extent ruminant microbiomes can be controlled by the host animal and identify characteristics of rumen microbiome axis that determine productivity methane emissions. core microbiome, phylogenetically linked with a preserved hierarchical structure, identified. 39-member subset formed hubs in co-occurrence networks linking structure genetics phenotype (methane emissions, blood metabolites, milk production...
Abstract How complex communities assemble through the animal’s life, and how predictable process is remains unexplored. Here, we investigate forces that drive assembly of rumen microbiomes throughout a cow’s with emphasis on balance between stochastic deterministic processes. We analyse development microbiome from birth to adulthood using 16S-rRNA amplicon sequencing data find animals shared group core successional species invaded early persisted until adulthood. Along factors, such as age...
The hologenome concept proposes that microbes and their host organism are an independent unit of selection. Motivated by this concept, we hypothesized thermal acclimation in poikilothermic organisms, owing to inability maintain body temperature, is connected microbiome composition. To test hypothesis, used a unique experimental setup with transgenerational selective breeding scheme for cold tolerance tropical tilapias. We tested the effects selection on gut transcriptomic response....
Abstract Sustainable aquafeed production requires fishmeal replacement, leading to an increasing use of plant-derived ingredients. As a consequence, higher levels antinutritional substances, such as non-starch polysaccharides and phytate, are present in aquafeeds, with negative effects on fish performance, nutrient digestibility overall gut health. To alleviate these effects, providing exogenous digestive enzymes and/or probiotics can be effective solution. In this study, we tested the...
Five cultures of microalgae (Chlorella minutissima, Tetraselmis chui, Nannochloropsis sp., Arthrospira platensis and Isochrysis sp.) with no culturable bacteria were tested for their ability to inhibit the growth six Vibrio bacterial strains (V. parahaemolyticus, V. anguillarum, splendidus, scophthalmi, alginolyticus lentus). The influence light on antibacterial activity was investigated. All inhibited compared control treatments (P < 0.05), not influenced by presence or absence light. In...

The establishment of the early-life gut microbiota plays an important role in fish development and influences host's health status growth performance. Different rearing conditions can impact initial colonization microbiota, while addition probiotics may also affect such colonization. However, how this larvae survival remains largely unexplored. In study, 3-day old Nile tilapia embryos were hatched until 9 days post fertilization (dpf) three systems, including one flow-through system (FTS)...
Abstract Background Fish gut microbial colonisation starts during larval stage and plays an important role in host’s growth health. To what extent first could influence the microbiome succession later life remains unknown. In this study, Nile tilapia embryos were incubated two different environments, a flow-through system (FTS) biofloc (BFS); hatched larvae subsequently cultured systems for 14 days of feeding (dof). then transferred to one common recirculating aquaculture (RAS1, garden,...
Yellowtail kingfish (Seriola lalandi) is a fast-growing fish species. One of the challenges farming yellowtail in recirculating aquaculture systems their poor faeces integrity, also referred to as ‘diarrhoea-like’ faeces. Whether diarrhoea-like occur under conditions when feeding on its natural feed items or are diet induced, unclear. This study assessed effect type (pelleted vs. feed) faecal characteristics and waste production kingfish. Three dietary treatments were studied over 35-d...
Abstract The constant increase in aquaculture production has led to extensive use of antibiotics as a means prevent and treat diseases, with adverse implications on the environment, animal health commensal microbes. Gut microbes are important for host proper functioning, thus evaluating such impacts is highly crucial. Examining antibiotic impact gut segments different physiological roles may provide insight into their effects these microhabitats. Hence, we evaluated effect feed-administrated...
The addition of external carbohydrate in Pacific white shrimp (Litopenaeus vannamei) culture has shown positive effects on water quality and performance. However, this practice requires additional skills labor, therefore may not be widely adopted. This research investigated the potential to combine carbon source feed one pellet culture. used experiment was corn starch. executed 6 indoors mesocosms tanks, with full control source, temperature, light intensity duration. three treatments...
This study assessed the effect of different dietary ingredients on quantity and characteristics faecal waste produced by rainbow trout (Oncorhynchus mykiss). Seven were tested: fish meal (FM), mussel (MM), poultry wet rendered (PM-W) or dry (PM-D), insect (IM), single cell protein (SCP) brewers grain (BGP). Eight experimental diets formulated: a control diet (CON) being predominantly plant-based seven test diets, which contained 70% CON 30% one ingredients. Rainbow juveniles (65 g, 30...
Yellowtail kingfish have a poor faecal integrity when fed with pelleted diets which may be due to the presence of dietary starch. Moreover, whether starch interacts plant protein ingredients, is not known. In this study, we investigated effect level, source and their interaction on waste production characteristics (visual appearance, removal efficiency particle size distribution (PSD)). Four were formulated according 2 × factorial design (starch level source). The was tested by either...
