    Take the guesswork out of predator prey interaction with the V5 Predation Tag

    For several decades, researchers have been using underwater acoustic telemetry technology to study animal behaviour, movement, physiology and survival in marine and freshwater environments. But to determine and understand predation events, scientists have relied on guesswork or applied subjective criterion to data analysis which could potentially lead to inaccurate results.

    VEMCO’s V5 Predation Tags permit exploration of novel questions and important research while increasing the certainty with which researchers can interpret their telemetry results.

    The predation tag provides a direct measure of digestion wherein stomach acids digest a polymer. It is a superior technique to using indirect measures of activity such as acceleration.

    The tag ID changes approximately 3 to 5 hours after predation and its trigger success rate is 100%.

    Over the past two years, we have conducted over 140 control and experimental trials (12°C to 24°C) with an independent University research group. Details about the trials can be found in this recently published research paper.

    Compatible with VEMCO’s new HR2 receiver and the VR2W-180 kHz receiver, the predation tag supports two acoustic transmission systems: PPM (Pulse Position Modulation) and HR (High Residence). For more information, see Downloads section.
