The hematological and plasma biochemical parameters of P. unifilis were analyzed at 60, 120, and 180 days of the feeding trial. The increase in total thrombocyte, leukocyte, lymphocyte, heterophil, and eosinophil numbers, besides high respiratory burst activity showed an improvement in animal immune defense response to incremental protein in diets, acting together to maintain the integrity of the tissues against antigens and infectious agents. Elevated subadult P. unifilis plasma total cholesterol and triglyceride levels observed after increasing the feeding time (until 180 days) with incremented protein levels in artificial diets during captivity are a nutritional warning, related to the condition of being less physically active. Based on these results, periodic physiological evaluations are particularly important to ensure the healthy and adequate nutritional conditions of captive-bred animals, such as maintaining lower stocking densities of animals to avoid stress and, if possible, providing them with fresh food in addition to extruded artificial feed.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43519322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study used five experimental groups of fish with a mean weight of 0.69 ± 0.31 g; three groups were fed quercetin loaded mesoporous silica nanoparticles (QMSNs) incorporated diets (0.25 g kg−1 – QMSNs 0.25, 0.50 g kg−1 – QMSNs 0.50, 1 g kg−1 – QMSNs 1), while the control group was fed an additive-free basal diet. The fifth group was a strict quercetin-only diet (0.25 g kg−1 – QMD). Feeding trial was done for 90 days prior to the experimental challenge with Klebsiella pneumoniae and Streptococcus agalactiae. Dietary quercetin loaded mesoporous silica nanoparticles (QMSNs) especially at 0.50 g kg−1 significantly increased digestive enzymes, phagocytic index, potential killing activity, respiratory burst activity, and Serum antibacterial activity. Furthermore, antioxidant-related genes [superoxide dismutase (SOD) and catalase (CAT)] and metabolic enzymes [serum glutamic oxaloacetic transaminase (AST) and serum glutamic pyruvic transaminase (ALT)] were found to be upregulated in the muscle and hepatopancreases of fish fed with 0.50 g kg−1 QMSNs. Survival rates were significantly higher in the 0.50 g kg−1 QMSNs group at the end of the 15th day challenge period compared to all other treatment groups. As a result, feeding Nile tilapia with 0.50 g kg−1 QMSNs for 90 days may be sufficient to improve fish immune response, antioxidant status, and survival rate against Klebsiella pneumoniae and Streptococcus agalactiae. As a result, quercetin loaded mesoporous silica nanoparticles (QMSNs) can be recommended as a dietary substitute against K.pneumoniae and S. agalactiae in Nile tilapia.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45890024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Altered microbial communities due to the application of probiotics were studied using 16S rRNA-based Illumina sequencing. The results suggest that the probiotics-treated group showed higher richness; the control group was even as measured by alpha diversity indices. The abundance of Proteobacteria was higher in the probiotic-treated group (94.85%) compared to the control (58.29%). At the genus level, the probiotics group was dominated by Vibrio (44.17%), Rhodobacteraceae_unclassified (25.22%), Catenococcus (12.89%), Pseudoalteromonas (4.76%), and Kordia (1.53%); Tenacibaculum (24.29%), Catenococcus (19.38%), Vibrio (7%), Gammaproteobacteria_unclassified (6.6%), Fluviicola (5.91%), and Chlamydiales_unclassified (4.61%) dominated in the control group.

A high plant-ingredient basal diet was supplemented with exogenous xylanase at 0 (Control diet), 100, 150, and 200 ppm, and fed to on-growing (initial weight ca 500 g) fish for a duration of 91 days. Growth parameters, fillet proximate composition, hindgut microbial diversity, hindgut short-chain fatty acid concentration, and blood chemistry parameters were monitored. There were no effects on growth parameters, fillet proximate composition, hindgut short-chain fatty acid concentration, and blood chemistry parameters. Dietary xylanase supplementation caused a significant shift in hindgut microbial diversity, where the 200 ppm treatment showed significantly lower Shannon diversity (2.15 ± 0.13) than the control (2.78 ± 0.21). The significantly lower microbial diversity indicates that enzyme supplementation selectively benefitted certain microbial populations in the hindgut, presumably through the release of prebiotic compounds during non-starch polysaccharide hydrolysis. It is concluded that dietary xylanase supplementation can significantly impact hindgut microbial communities in on-growing African catfish, and it is recommended that future work investigate whether dietary xylanase supplementation can benefit aquaculture production performance in younger fish.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42813987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
