Tissue-Specific Lipidomic and Metabolomic Profiles of Coilia nasus Fish

Processed untargeted metabolomics and targeted lipidomics data matrices, along with otolith strontium-calcium transect measurements, for mature female Coilia nasus fish. The dataset, 2.8 MB in size, was authored by hongyi Guo and last updated on April 19, 2026. It provides annotated compound abundances and point-by-point elemental ratios to compare physiological states between estuarine and freshwater habitats.

Use Cases

• Compare tissue-specific metabolic profiles between estuarine and freshwater fish populations based on annotated compound data.
• Analyze quantitative lipid composition differences in specific tissues mentioned in the description.
• Correlate otolith Sr/Ca transect measurements with habitat use history for individual fish.
• Investigate physiological divergence in mature female Coilia nasus using integrated multi-omics data.

Strengths

• Dataset size is precisely 2.8 MB, indicating a manageable download.
• Includes three distinct data files covering metabolomics, lipidomics, and otolith chemistry.
• Data is processed and annotated, as stated in the description.
• Released under the permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
