Have you ever wished you can have the fish show you where they like to hang out in your lake? ---- What specific benthic habitats do they prefer? -----Where do they aggregate when spawning or feeding?
Well, now you can, using our new multibeam imaging sonar technology!
Map habitat and detect & geo-locate tagged fish all at the same time. No expensive receiver array required. Just uses a side-looking sonar deployed from a small moving boat. Activate and detect tags using a sonar beyond 100 m range. Detection swath is 120o.
The integrated sonar and tag system is ideal for identifying & mapping lacustrine spawning areas, or to assess Sturgeon and American Eel in large rivers.
The transponder tags (built by Sonotronics Inc.) are designed to "wake up" and broadcast its ID code upon hearing a ping from the transponder tag activator system (Kongsberg TTAS). The ID, range and geo-spatial location of the tagged fish is recorded and decoded by the Kongsberg M3 multibeam sonar; up to 4 times a second! As the tagged fish moves out of the beam, the tag goes back to sleep, thus conserving battery life. The ability for passive acoustic transponder tag to remain quiet for long periods of time between activation events gives these tags a potentially exceptional long battery life (4+ years) and allows the user to monitor individual fish over multiple years in habitats where fish may return on an annual basis (spawning tributaries and shoals, home ranges, feeding grounds, etc.).
