Survivorship PAT

The sPAT is a pop-up archival transmitting tag (PAT tag, also known as a PSAT) specifically optimized for short-term survivorship studies. The sPAT uses a suite of sensors and algorithms to monitor the status of the tagged animal for up to 60 days.



  • The sPAT is very easy to deploy thus can be used by recreational and commercial fishermen.
  • The sPAT is attached to the fish by a tether and anchor.
  • We provide a variety of anchors for different species.
  • No programming of the tag is required. The sPAT will automatically deploy when it is submerged in seawater.
  • A corrodible pin allows the release of the sPAT from the fish 30, 45, or 60 days after deployment or when certain conditions indicating the tag is no longer on a swimming fish (conditional release) are met.
  • Once released from the fish, the tag floats to the surface and transmits its data to Wildlife Computers Portal for processing. Wildlife Computers pays for all the Argos charges.

Data Products

  • Pop-up date and location via Argos
  • Delta Light—changes in delta light can be an indicator of predation/ingestion
  • Daily min/max depth and temperature (to confirm the tag was attached to a swimming animal)
  • Depth Time Series for five days prior to release

The operational definition of “survivorship” is when the tag is still attached to a swimming animal 30 days after deployment.
