“…Supplementing 30% SBM diet with the functional immunostimulant combination significantly improved shrimp body weight, feed utilization, innate immune parameters, and resistance to V. parahaemolyticus infection. The immunostimulatory activity as well as the overall health‐promoting properties of brewer's yeast (Burgents et al, 2004; Xu et al, 2021; Zhang et al, 2021), nucleotides (Andrino et al, 2012; Guo et al, 2016; Novriadi et al, 2021; Shankar et al, 2012), vitamin C (Asaikkutti et al, 2018; Kong et al, 2021), and vitamin E (Y. Li et al, 2019) in shrimp culture are well‐documented. These immunostimulants were found to enhance resistance to a variety of shrimp pathogens including Vibrio spp.…”

Soybean meal (SBM) is widely used in shrimp feed agro‐industry as a fish meal (FM) replacement. However, high levels of SBM may compromise animal health as a result of nutrient imbalance. This study aimed to investigate the effects of feed enzyme combination (a mixture of 6‐phytase, serine protease, and endo‐1,3(4)‐β‐glucanase) and functional immunostimulant combination (a mixture of brewer's yeast, nucleotides, vitamin C, and vitamin E) in improving the overall health of Pacific white shrimp fed soybean‐based diet. Four diets were formulated with different amounts of SBM, FM, and poultry meal (PM): 0% SBM (with 25% FM and 12.6% PM), 30% SBM (with 12.5% FM and 5.7% PM), 30% SBM plus 0.045% feed enzymes, and 30% SBM plus 0.1% functional immunostimulants. The postlarvae were fed the test diets for 45 days. Then, the body weight, survival, FCR, Vibrio spp. count, and immune responses were analyzed. The resistance of shrimp to Vibrio parahaemolyticus infection was also evaluated. The results suggest that the diet with 30% SBM was deleterious to the shrimp's health. Feed enzymes and functional immunostimulant supplements improved overall performance, immune function, and resistance to V. parahaemolyticus infection of shrimp fed the diet containing 30% SBM compared with the 30% SBM diet without feed supplements.

“…There is increasing interest in the use of functional feeds that contain natural supplements such as probiotics and prebiotics to improve fish growth and health ( Akhter et al., 2015 ; Huang et al., 2015 ; Dawood and Koshio, 2016 ). Diets supplemented with probiotics have been studied in many aquatic animals, such as tilapia ( Rmm et al., 2020 ), shrimp ( Sadat Hoseini Madani et al., 2018 ), grass carp ( Liu et al., 2018 ; Qi et al., 2020 ) and crayfish ( Xu et al., 2021 ), showing positive effects on improving water quality, increasing nutrient utilisation, enhancing immune status and disease resistance ( Kiron, 2012 ; Yang et al., 2015 ; Hoseinifar et al., 2016 ). The most widely-investigated probiotics include Bacillus sp.…”

The influence of dietary probiotic Bacillus amyloliquefaciens on the growth performance, digestive enzyme activity, immune parameters and disease resistance of yellow catfish (Pelteobagrus fulvidraco) was evaluated. Commercial diet (C) or diet containing 106 cfu/g B. amyloliquefaciens (T) was fed for 4 weeks, and final weight (FW), specific growth rate (SGR) and feed conversion ratio (FCR) were improved (p<0.05) in the T group. Dietary B. amyloliquefaciens increased protease and amylase activities in the digestive tract after 2 and 4 weeks, respectively. Respiratory burst (RB), plasma lysozyme (LZM) activity, total antioxidant capacity (T-AOC) and superoxide dismutase (SOD) activity were also elevated (p<0.05). Immune-related genes signal transducer and activator of transcription 1 (STATA-1), immunoglobulin M (IgM) and C-type lectin (CTL) were upregulated (p<0.05), but interleukin-1 β (IL-1β) was not (p >0.05). Intestinal microbiota analysis showed that the community structure was significantly different between the two groups; the relative abundance of Cetobacterium was increased but Plesiomonas was decreased in T. Moreover, challenge tests showed that the resistance of fish fed B. amyloliquefaciens against Aeromonas veronii and Edwardsiella ictaluri was significantly enhanced (p<0.05). In conclusion, dietary supplementation of B. amyloliquefaciens can effectively improve the growth performance, digestive enzyme activity, immune responses, intestinal microbiota composition and disease resistance of yellow catfish.

“…Among them, the abundance of Romboutsia , Lactobacillus , and Cetobacterium significantly decreased with increasing Del concentrations. However, Lactobacillus and Cetobacterium are important beneficial bacteria in the intestine ( 104 ). For example, Lactobacillus can reduce the intestinal pH, which might contribute to overcoming pathogen challenges ( 105 ).…”

Deltamethrin (Del) is a widely used pyrethroid insecticide and a dangerous material that has brought serious problems to the healthy breeding of aquatic animals. However, the toxicological mechanisms of Del on channel catfish remain unclear. In the present study, we exposed channel catfish to 0, 0.5, and 5 μg/L Del for 6 h, and analyzed the changes in histopathology, trunk kidney transcriptome, and intestinal microbiota composition. The pathological analyses showed that a high concentration of Del damaged the intestine and trunk kidney of channel catfish in the early stage. The transcriptome analysis detected 32 and 1837 differentially expressed genes (DEGs) in channel catfish trunk kidneys after exposure to 0.5 and 5 μg/L Del, respectively. Moreover, the KEGG pathway and GO enrichment analyses showed that the apoptosis signaling pathway was significantly enriched, and apoptosis-related DEGs, including cathepsin L, p53, Bax, and caspase-3, were also detected. These results suggested that apoptosis occurs in the trunk kidney of channel catfish in the early stage of acute exposure to Del. We also detected some DEGs and signaling pathways related to immunity and drug metabolism, indicating that early exposure to Del can lead to immunotoxicity and metabolic disorder of channel catfish, which increases the risk of pathogenic infections and energy metabolism disorders. Additionally, 16S rRNA gene sequencing showed that the composition of the intestinal microbiome significantly changed in channel catfish treated with Del. At the phylum level, the abundance of Firmicutes, Fusobacteria, and Actinobacteria significantly decreased in the early stage of Del exposure. At the genus level, the abundance of Romboutsia, Lactobacillus, and Cetobacterium decreased after Del exposure. Overall, early exposure to Del can lead to tissue damage, metabolic disorder, immunotoxicity, and apoptosis in channel catfish, and affect the composition of its intestinal microbiota. Herein, we clarified the toxic effects of Del on channel catfish in the early stage of exposure and explored why fish under Del stress are more vulnerable to microbial infections and slow growth.
