The event during which a previously PIT-tagged fish is detected by unattended or remotely operated detection equipment at a location other than an interrogation site and is not handled. It differs from a Recapture event in that the fish is not handled, only detected. It differs from an interrogation record in that the detection occurs opportunistically in a location that is not a registered interrogation site. Multiple passive recapture events are allowed for each PIT tag code as long as the Event Dates are not the same.
