Bioactive substances can be incorporated into protective matrices to ensure safe ingestion and controlled release into the posterior digestive tract. Polyethylene glycol and alginate are promising and frequently applied substances in the oral administration of pharmaceutical substances; however, their direct influence on the intestinal tract or inflammatory response is not well investigated in aquaculture fish. In the current study, these two substances were evaluated separately and in combination. They were included in a commercial diet for juvenile rainbow trout (18.7 ± 0.1 g) and applied over 22 days in controlled feeding to determine possible gut alterations and inflammatory responses. Three different sections of the intestine, the anterior pyloric caeca, the mid-intestine, and the posterior intestine, were histologically examined, and expression of inflammatory genes was measured in each. The inclusion of polyethylene glycol in the diet led to a significant reduction of villus height in the pyloric caeca and thus a significant reduction in active surface area. In the mid-intestine, alginate inclusion resulted in a significant reduction of the mucus-secreting goblet cells and a significant increase in villus width. In the posterior intestine, polyethylene glycol inclusion caused a significant increase in number of large vacuoles present; the addition of alginate buffered this effect. The results of the histological evaluation indicated symptoms that are usually evident in intestinal inflammation and can reduce functions of the respective intestinal segments. No significant increases in pro-inflammatory gene expression tumor necrosis factor-α, interleukin (IL)-8, or IL-1β were present, indicating no severe inflammatory response. Based on the observed histological impairments, negative consequences such as reduced efficiency of an oral vaccine or productivity of aquaculture rearing due to hindered nutrient digestion can be considered unlikely.</p>","PeriodicalId":17284,"journal":{"name":"Journal of The World Aquaculture Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jwas.13006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45433851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Applying these methods to pond samples allowed for the identification of 1488 genera, primarily within four dominating phyla: Actinobacteriota, Bacteroidota, Cyanobacteria, and Firmicutes. High variation was observed between individual ponds and sampling timepoints; only 18 of the 1488 genera were found in relative abundances ≥1% in all ponds from at least one sampling point. Despite this variation, consistent results could be observed. Samples obtained from the month of September had the highest number of observed genera, and samples from June had the lowest.

While the importance of monitoring and reporting of AqGR is becoming more and more apparent among different stakeholders, efforts to date are still insufficient (FAO, <span>2022</span>).</p><p>A common method to estimate the AqGR is genotyping, which is a process of determining the genotype at positions within the genome of an individual and comparing it to other individuals' sequences. It is often used to understand association between genotype and phenotype. Sequence variations like single-nucleotide polymorphisms (SNPs) or microsatellite loci are applied as markers in linkage and association studies to determine genes relevant to specific traits. SNPs are the most common sequence variant widely used in genome-wide association studies (GWAS). With more and more SNPs being discovered, SNP genotyping technologies have been greatly promoted and include low-throughput and high-throughput methods.

Our findings indicate that changes in water color were associated with anomalies in these parameters, with water temperature anomalies being the best indicator for early detection. In fact, the top 5% of water temperature anomalies could predict over 40% of the water color changes. Additionally, pH anomalies occurred immediately after the color changes.
