    • Counts, Fish Weights, and Spectral Data from a Juvenile Chinook Salmon Polyester Microplastic Fiber Exposure Study

    Metadata Updated: January 6, 2026

    This release includes all data collected in support of a juvenile Chinook salmon exposure study designed to understand the retention of microplastic clothing fibers (hereon refered to as "microfibers") after feeding. To understand the potential impacts of microfiber ingestion to fish, we ran a feeding experiment with juvenile Chinook salmon to determine if ingested fibers are retained and/or digestion rates altered over a full, experimentally determined, 10 day digestion period. Data includes: fish weights, microfiber counts, and quality assurance (QA) data for the experiment. QA steps are detailed in the process section of the metadata.
