Small Size Opens Up New Research Avenues
Weighing less than 0.3 grams and measuring just 15 mm, the V3D tag is the smallest predation transmitter available today and enables researchers to track and monitor smaller fish and a broader range of species than ever before.
Its predation identification capability means researchers will know with greater certainty if the animals they tagged have been eaten by a predator. The V3D operates at 307 kHz.
Use Predation Tags To:

Monitor Animals Navigating Around Dams and Barriers

Track Hundreds of Small Animals Simultaneously

Conduct Studies in High Flow, High Noise Environments
Innovasea biologist Dale Webber explains how researchers track fish in noisy underwater environments like fast flowing rivers and around hydroelectric facilities.
More Options to Suit Your Study with HR and HTI Coding
V3 tags also offer the ability to alternate between High Residence (HR) and HTI coding schemes. That enables researchers to maximize system performance across more environments while allowing for cross-compatibility with HTI equipment.
HR is suited to tracking many fish at once over a short period of time, while the HTI coding is extremely effective in noisy and reflective environments. In the field a researcher could use HR to track animals as they make their way downstream and then switch to HTI as the fish approach a dam or other structure to maximize detection and positioning probability.
V3D Predation Tag Undergoes Extensive Trials
In the fall of 2021, FISHBIO performed a comprehensive trial of Innovasea’s V3D predation tags to quantify performance of its corrosive trigger and evaluate its efficacy in detecting a predation event.
And the Results are In:
