Acoustic Tagging Studies – Beyond Presence/Absence

Published on

Acoustic tags can provide information about fish populations. For example, presence/absence.
If detections are uniformly spaced to a high level of precision, these detections can assess fish behavior.
Example behaviors include:
Moving towards and away
Holding
Defecation
Downstream migration
Fish passage
Searching
Predator avoidance

This presentation illustrates examples of how fish are being monitored in 2D and 3D using acoustic tag technology to improve fisheries management along the West coast and elsewhere in the world.

  • Timing of the start of each transmission is precisely controlled by a microcontroller within each tag.
  • Upstream side of barrier. Either moving toward and away from hydrophone.
  • Behavior can be further interpreted when tag detection histories are observed and analyzed in relation to each other and not as isolated tag detections. In this presentation, we document the behaviors of acoustically tagged fish and discuss the implications for fish survival estimates in the Sacramento-San Joaquin Delta.
