Abstract
  • 1. Acoustic telemetry is increasingly used to observe and monitor animal movements in aquatic environments. Practical deployment mechanisms are needed to sustain consistent data flows in challenging environments.
  • 2. A tripod frame was developed to facilitate the deployment of acoustic receivers on the seabed, allowing for the recovery of all equipment with an acoustic release system.
  • 3. The procedures of deployment and recovery proved to be practical and efficient during a field trial in the North Sea. Compared to a common cabled design, the tripod frame realized a significantly higher detection probability and performed consistently better at greater distance and louder ambient noise.
  • 4. In the context of ocean observation in challenging environments, the tripod frame is a useful tool for temporary and continuous monitoring of tagged fish presence, potentially fitted with additional instruments.
