Footage of Santa Ana Sucker (Pantosteus santaanae) from passive (or stationary) camera. Part of a USGS study on the effectiveness and safety of the PIT tagging sampling method.

An open-source image recognition program was used to detect the fish and lures in the videos. The program was “trained” to recognize the fish and lures by exposing it to approximately 800 images of fish and non-fish.

Active (or moving) camera footage of Santa Ana Sucker (Pantosteus santaanae). Cameras were attached to “selfie sticks” and walked up and down the raceways (or fabricated streams).
