TL;DR: The results of this study strongly suggest that dietary supplement of B. subtilis HAINUP40 can effectively enhances the growth performance, immune response, and disease resistance of Nile tilapia.

TL;DR: It is shown that a prebiotic as part of a synbiotic is hydrolyzed to mono- or disaccharides as the sole carbon source with diverse mechanisms, thereby increasing biomass and colonization that is established by specific crosstalk between probiotic bacteria and the surface of intestinal epithelial cells of the host.

TL;DR: The results indicated that optimal SB supplementation improved the fish growth performance and intestinal growth and function and MSB was superior to PSB on improving growth and enhancing intestinal immune function of fish.

TL;DR: Although ingestion of PVC‐MPs provoked few significant effects in the main immune activities of gilthead seabream compared with the values found in control fish, PVC‐ MPs are recognized by the fish as stressors.

TL;DR: It is indicated that chronic exposure to sub‐lethal levels of sulfide could lead to damage of the gut structure, stimulate the response of the inflammatory and immune systems, and shape the structure of the Gut microbiota in L. vannamei.

TL;DR: The results showed that low temperature could decrease total blood cell count, inhibit cell viability, and subsequently lead to DNA damage, and that caspase‐dependent pathway could play important roles in low temperature‐induced apoptosis in fish.

TL;DR: Dietary supplementation of C. butyricum could improve the growth performance, increased intestine SCFA content and body crude protein content, modulated intestine digestive capacity, and enhanced intestine immune function of L. vannamei against ammonia stress.

TL;DR: The present results suggested that the combination of these natural substances could be considered as potential feed‐additives for aquaculture farmed fish.

TL;DR: Results indicated that golden pompano fed a diet supplemented with DE could significantly promote its growth performance, feed utilization, body protein deposit, immune ability, hepatic and plasma antioxidative enzyme activities and improve its resistance to infection by Vibrio harveyi.

TL;DR: Using WMB as carbon source could make up for a reduction in dietary protein levels of 10% and improve growth performance, and the immune and antioxidant status of O. niloticus.

TL;DR: The study demonstrated that the probiotics survived in the intestine of striped catfish after 90 days of feeding, and found that the dietary supplementation of a mixture of B. amyloliquefaciens and B. pumilus at 5 × 108 CFU g−1 can be used to improve the health and growth rate of stripedCatfish.

TL;DR: Findings show that the tested organic acids and essential oils mixture beneficially affects intestinal microflora and improves immune response and disease resistance of L. vannamei.

TL;DR: It is suggested that L. plantarum has improved the anti‐stress capacity of L. vannamei and could serve as a potential feed additive that helps shrimp to overcome environmental stresses.

TL;DR: The invasion of pathogen could change the intestinal microbiota composition and induce intestinal innate immune responses in zebrafish, and the mRNA levels of antimicrobial peptide genes lectin, hepcidin and defensin1 were upregulated in the intestine after pathogen infection.

TL;DR: Fulvic acid improves growth performance and intestinal health condition of loach, indicates that fulvic acid could be used as an immunoenhancer in loach culture.

TL;DR: Results indicated that oral supplement of B. subtilis at 107 CFU/g kg−1 diet could be a more promising source and dose compared to probiotic L. plantarum in freshwater aquaculture.

TL;DR: A pathobiological study using Vibrio parahaemolyticus (VP) strain isolated from vibriosis affected shrimp (Penaeus vannamei) farms in Kancheepuram and Thiruvallur districts of Tamil Nadu during August 2014 to February 2015 showed that these immune related genes could be used as markers for assessing the immune status of P. vannomei.

TL;DR: The diet containing 109 cfu (kg diet)−1 probiotic mixture is recommended to improve the growth and health status of Asian seabass and a synergistic effect of combined probiotics containing E20, BD6, P13, and LW2 was observed to improve both the growth performance and healthstatus of fish.

TL;DR: Results of this study indicated that the immune status and welfare of white shrimp can be seriously impaired in the HD condition (i.e., ≥500 m−3) in biofloc systems and can be used to determine suitable stocking densities in the white shrimp farming industry using the bio floc system.

TL;DR: Dietary &bgr;‐glucan in dosage of 0.1% and 0.2% are beneficial for promoting growth in rainbow trout and enhancing resistance against A. salmonicida, and could play an important role in regulating stress‐ and immune‐related factors in rainbow Trout to more quickly fight against bacterial infection.

TL;DR: The findings imply that V. anguillarum infection substantially disrupted the compositions and interspecies interaction of ayu gut bacterial community, thereby altering gut microbial‐mediated functions and inducing host immune responses.

TL;DR: Results revealed that PHB could improve the growth performance, modulated intestinal digestive and immune function, increased intestinal SCFA content and body composition in L. vannamei.

TL;DR: It is demonstrated that dietary administration of U. dioica enhanced growth and stimulated fish immunity; thus, enabling the fish to be more resistant against bacterial infections.

TL;DR: High concentration of ammonia in aquatic system leads to detrimental effects on the health of aquatic animals, however, the mechanism underlying ammonia‐induced toxicity is still not clear, and histopathology and TUNEL assays results confirmed that apoptosis was induced in liver when fish had suffered HEA.

TL;DR: The identification of the basic mechanisms of immunity and their modulation in mussels can give important information for the possible utilization of this species as an invertebrate model for studies on innate immunity, future immunotoxicological studies, and predict changes in the community for the future.

TL;DR: The present results indicated that dietary inclusion level of at least 18% MW could improve the immune response and the bacterial resistance of yellow catfish without any negative growth effects.

TL;DR: The results of this study indicated that OnMBL, possessing apparent agglutination ability to bacterial pathogens, might be involved in host defense against bacterial infection in Nile tilapia.

TL;DR: Ammonia exposure could induce the immune response in crucian carp, and alter the gut microbial community, and the results revealed that ammonia exposure concentration or time can alter the intestinal microbial community.

TL;DR: Glu could attenuate LPS induced the oxidative damage by Nrf2 signal pathway and depress LPS inducing inflammation response, apoptosis, and barrier function, and the present results showed Glu could alleviated LPS‐induced oxidativeDamage by regulating antioxidant enzyme gene expression and NRF2 pathway.
