Fish Monitoring Work Group - PIT Tag Data & Analysis 2025 Webinar Series

Washington's Fish Hatchery and Rearing Areas (2023) (~6.5Mb)

I came across an interesting map of Washington state’s fish hatchery and rearing facilities during the course of taking the Pacific Northwest Aquatic Monitoring Partnership’s PIT Tag Data & Analysis 2025 Webinar Series.

Software tools for managing the massive and complex amount of data produced by PIT-tag arrays in the Columbia River Basin of salmon and steelhead have been developed to allow researchers to access the accumulated data on nearly 53 million PIT-tagged fish since 1987. The PTAGIS database containing the results of over 267 million detection events from the 283 interrogation sites across the Columbia River Basin, with 842,171 unique fish were detected in 2021 alone.

PTAGIS is continuously updated with data contributions from around 40 different organizations and includes detailed records of fish tagging events, detection, recaptures, and recoveries. In 2021 the system processed 820,000 data files, inserting or updating 26 million records. Included are individual tag histories, detection timestamps, location metadata, and biological data such as species, length, and origin.

The Columbia Basin PIT Tag Information System (PTAGIS) operated a network of 283 interrogation sites across the Columbia River Basin.

Information about the webinar series can be found at Fish Monitoring Work Group – PIT Tag Data & Analysis 2025 Webinar Series. There is no charge to register and recordings of the sessions are available.

A disclosure, I now use “Synthia” my OpenAi bot to develop much of the content for my website.
