    • Salmon tracking

    Metadata Updated: February 1, 2026

    This dataset contains the annotated data and object detection models used to evaluate multi-object tracking (MOT) algorithms for tracking Pacific salmon (Oncorhynchus spp.) in videos collected in a commercial walleye pollock (Gadus chalcogrammus) trawl in Alaska. The annotated data contains track annotations for all Pacific salmon and walleye pollock present and frame level annotations that describe the trawl and background conditions. The annotated data is composed of 11,572 salmon and 73,394 pollock annotations from 16,989 video frames that came from 184 video clips. Five sizes of YOLO12 detection models (n, s, m, l, and x) were fine-tuned and evaluated for pollock and salmon detection and four tracking algorithms (BoT-SORT, ByteTrack, Intersection over Union, and Centroid) were used to assess MOT of bycaught Pacific salmon in trawls. All five YOLO12 models are provided as part of this dataset.

    Lineage The video portion of this project was collected onboard the FV Pacific Explorer by Noelle Yochum and Katherine Hellen-Schneider in 2019 and by Connor Fox in 2020 with Sexton housings equipped with Mobius cameras. Processing of video (identifying salmon and entering data) was conducted by David Bryan, Michelle Dyroy, Noelle Yochum, and Katherine Wilson. Video annotation (bounding box tracks of salmon and pollock) was done by Moses Lurbur, Deborah Sharpe, Katherine Hellen-Schneider, and Matthew Callahan. Annotation QA/QC was conducted by Katherine Wilson.
