A short film covering the origins of using PIT tags in fish in the Columbia River Basin, as remembered by Earl Prentice.

This tour follows the life journey of the fish to tell the story of PTAGIS. You'll see how PTAGIS tracks fish marked with a PIT tag, and makes valuable data accessible to researchers seeking information about fish movement and behavior. The tour was originally an interactive flash application, but has been converted into a video following the discontinuation of Adobe Flash in January 2021. There is no sound in this video.
