    • National Bycatch Report 2010 - Present

    Metadata Updated: May 24, 2025

    This system collects bycatch data and fishery landings data from all five NOAA Fisheries Regions and automates the generation of the tables required to publish the National Bycatch Report (NBR). The NBR documents bycatch estimates, using observer data and self-reported logbook data, for all fisheries for which this information is available. NBR bycatch estimates are fishery- and species-specific. The NBR includes bycatch estimates for fish, marine mammals, sea turtles, seabirds, and corals. Future NBR reports will include additional bycatch estimates as new fisheries are monitored and new data are analyzed. Over time, the NBR, along with other information sources, should help improve NOAA Fisheries' ability to monitor bycatch trends, improve stock assessments, and set fishery monitoring priorities, as well as serve as a useful data tool for NOAA Fisheries' management partners.

It is the responsibility of the user to determine whether or not the data is suitable for the intended purpose.
    Lineage Data that make up the National Bycatch Report (NBR) are collected by at-sea fisheries observers, who use notebooks or electronic reporting methods (for example, laptops or tablets) to record their data. These data are transmitted to regional observer programs, where the data are reviewed and validated by regional "debriefers" and other analysts. The data eventually are used to generate species-specific bycatch estimates using a variety of estimators including Binomial Based Ratio Estimators, Census, Combined Ratio Estimator, Delta Lognormal Model, Delta Method, Delta-Lognormal Based Ratio Estimator, General Additive Model, Generalized Lineal Model, Population Model, Ratio Estimator, Simple Ratio Estimator, and Target Fishery Extrapolation. Regional bycatch estimates are uploaded into the NBR database, and after review and approval, the estimates are published online in an NBR Update.
