White Hake Gut Microbiota and Population Genomics Data from Eastern Canada

Data collected in 2022 and 2023 integrates genotyping-by-sequencing and 16S rRNA gene amplicon sequencing for White Hake (Urophycis tenuis) in eastern Canada. The dataset includes genomic data from fin samples, gut microbiome data from intestine samples, and environmental parameters like depth, temperature, oxygen, and salinity. It was produced by Fisheries and Oceans Canada.

Use Cases

• Correlating gut microbiota composition with host population structure based on genomic analyses.
• Investigating the influence of environmental factors and fish length on microbiome variation.
• Identifying differentially abundant microbial taxa associated with ontogenetic diet shifts.
• Evaluating the role of taxa with chitin-degrading potential in fish consuming crustacean-dominated diets.

Strengths

• Integrates two complementary data types: population genomics and gut microbiome sequencing.
• Includes environmental parameters (depth, water temperature, oxygen, salinity) collected at most sampling sites.
• Data collected during standardized annual ecosystem monitoring surveys by Fisheries and Oceans Canada.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to sampling in eastern Canada.
