Bull Trout Summaries

Summary visualizations of PIT-tagged Bull Trout release and detection data for all years. The number of Bull Trout detected is dependent on the presence of instream arrays. Click on an image to view full size.

Initially, these summaries are static; data complete through 2024-12-31.

Cumulative counts are binned by year difference between release date and maximum detection date
Year(s) difference between release date and maximum detection date is calculated for each PIT-tagged Bull Trout with detection (interrogation or recapture) for all years of data, 1998-2024. Cumulative counts are binned by year difference.
Individual Release Hydrounits (HUC8) for number released and number detected of unique PIT-tagged Bull Trout for all years
Individual Release Hydrounits (HUC8) are tracked (if more than 500 Bull Trout released in all years) for number released and number detected of unique PIT-tagged Bull Trout for all years, 1998-2024.
Line plot of number of PIT-tagged Bull Trout released by month from 1998 to present.
