Specifications > MRR > Data Specification Passive Recapture Event |
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.
All of these fields must be completed before the data can be submitted to PTAGIS.
