Characterization of bacteria colonizing the mucosal layer of the gastrointestinal tract of Atlantic salmon farmed in a warm water region

Data is based on a study of farmed Atlantic salmon gut microbiome. Fish were sampled from farms and hatcheries in Tasmania, Australia.
1. Sequence data - 8 spreadsheets including bacterial sequence output from DADA2 (Galaxy Australia), read counts, and classifications based off GreenGenes2. The data was collected from samples from farmed Atlantic salmon over several surveys. Metadata summary file provides sources of sequences, animal ethics permits, and some sampling information.
2. Differential abundance analysis - 2 spreadsheets including transformations and statistics (p-values, effect sizes) for comparisons of read abundances for bacterial OTUs
3. Subsampled reads for the combined sequenced dataset to portray overall abundance trends by sample type and by season.

本数据集基于针对养殖大西洋鲑肠道微生物组的研究，实验样本采集自澳大利亚塔斯马尼亚州的养殖场与孵化场。
1. 序列数据：包含8份电子表格，涵盖由Galaxy Australia平台的DADA2工具生成的细菌序列输出结果、读长计数，以及基于GreenGenes2数据库的分类注释信息。该数据源自多次调研中采集的养殖大西洋鲑样本。元数据汇总文件提供了序列来源、动物伦理许可文件及部分采样相关信息。
2. 差异丰度分析：包含2份电子表格，涵盖用于比较细菌操作分类单元（Operational Taxonomic Unit，OTU）读长丰度的转换方法与统计参数（P值、效应量）。
3. 合并测序数据集的抽样子集读长数据，用于呈现按样本类型与季节划分的整体丰度变化趋势。
