The importance of the gastrointestinal microbiota (GM) in health and disease is widely recognized. Although less known fish than mammals, advances molecular techniques, such as 16S rRNA sequencing, have facilitated characterization GM, comprising resident autochthonous transient allochthonous bacteria. microbial diversity composition are strongly influenced by diet. High-protein diets, including alternative ingredients like plant insect proteins, modify impacting beneficial bacteria e.g. Cetobacterium . Lipids affect metabolism short-chain fatty acid (SCFA) production, while excessive carbohydrates can disrupt GM balance, causing enteritis. Dietary additives, probiotics, prebiotics, antibiotics, effectively modulate GM. Probiotics enhance immunity growth, prebiotics support bacteria, though effective against pathogens, may promote antibiotic resistance. Environmental factors, temperature, salinity, pollution, significantly influence Elevated temperatures salinity shifts alter composition, pollutants introduce toxins that compromise intestinal function diversity. Stress pathogen infections further destabilize often favoring pathogenic communicates with host via metabolites SCFAs, bile acids, neurotransmitters, regulating appetite, energy metabolism, immunity, neural functions. Additionally, influences immune system interacting epithelial cells stimulating responses. Despite recent advances, research needed to elucidate species-specific mechanisms underlying GM-host interactions, ecological implications diversity, its applications aquaculture optimize performance.

According to the Food and Agriculture Organization (FAO) from United Nations, aquaculture fish production surpasses fisheries it will continue grow globally in coming decades [1], contributing high quality food for increasing human population. Thus, farming is an important actor achieve UN-Sustainable Development Goals (SDGs) such as SDG 2 (Zero hunger), 12 (Responsible consumption production) 14 (Life below water) [2]. However, this industry faces several challenges that negatively impact its sustainability. For instance, sub-optimal nutrition, infectious diseases (caused by parasites, bacteria virus) environmental problems (e.g., increased seawater temperature, algal blooms) can decrease performance overall health, well increase mortality, leading economic losses sector [3][4][5]. Therefore, a resilient capable of coping with stressful conditions strengthen meet protein demands global population, essential deepen understanding metabolism, immune responses against pathogens hostmicrobiota interaction.In mammals, "immunonutrition" concept has been described nutritional interventions produce health-related effects, reducing risk pathogen infection improving healing process [6,7]. To contribute knowledge on topic importance (i.e., Atlantic salmon, Salmo salar; rainbow trout, Oncorhynchus mykiss; European seabass, Dicentrarchus labrax), scientific articles special issue "Chrono-Immunonutrition Aquaculture towards Robust Resilient fish" focused alternative feed ingredients, growth performance, modulation, health exposure microbe-associated molecular patterns suboptimal nutrition), microbiota characterization interaction host.Furthermore, analysis based different abstracts comprising revealed words "fish response", "diet effects", "feed", "microbiota", "gene expression", "stimulus" "meal" were most used concepts authors (Figure 1).

In addition, cultures splenic leukocytes stimulated EVs B. showed higher number IgM-secreting cells. Also, IgM + B MHC II surface levels antigen-processing capacities. Interestingly, antigen presentation bridge between response [15] these vitro results suggest immunomodulatory potential adjuvants or immunostimulants aquaculture.Linked nutrient absorption utilization, Martin [16], investigated properties L-methionine trout.

The ciliate parasite Ichthyophthirius multifiliis poses significant threats to grass carp (Ctenopharyngodon idellus) aquaculture. However, the limited understanding of host microbiota shifts and immune responses hinders effective control strategies. This study integrated analyses pathological indices, response skin/gill/gut after I. infection. A histopathological examination identified gill fin tissues embedded with multifiliis, accompanied by epithelial necrosis, inflammatory cell infiltration. Biochemical profiling revealed marked elevations in aspartate aminotransferase (AST), alanine (ALT), urea (UREA), creatinine (CREA) levels, indicating impaired hepatic renal function. Quantitative RT-PCR demonstrated up-regulation mucosal gene IgT pro-inflammatory cytokine TNF-α while increasing trend systemic IgM. 16S rRNA sequencing reductions skin diversity. At genus level, opportunistic pathogens Aeromonas Vibrio proliferated intestine, whereas Flavobacterium Candidatus Megaira increased gills. Correlation positive associations between Aeromonas/Vibrio abundance phenotype, contrasting negative correlations observed for Sphingomonas, Acinetobacter, Leifsonia. These findings demonstrate that infection induces microbiome dysbiosis potentially bacterial infections. investigation advances our tripartite host–microbiota–parasite interactions supports microbial community-based parasitosis fish culture.
