The Lotek M-Series MiniMAP acoustic transmitters are suitable for use on salmon smolts and similar small juvenile fish. Employing advantages of CDMA coding, these acoustic tags are compatible with Lotek MAP acoustic receivers configured for 200 kHz*.

The unique benefits of this system include support for tens of thousands of unique identification codes operating on a single acoustic frequency.

High noise immunity and collision resistance make these tags suitable for large scale fish tracking and positioning studies, particularly where short burst interval and fine spatial resolution is required and/or where hundreds of fish may congregate in the study area.

The tags have a temperature sensing option that transmits fish temperature data along with ID.

* MAP acoustic receivers are factory-configured for either 76 kHz or 200 kHz operation.
Actual number of codes is application specific - please consult with your Lotek representative for details.

Miniature MAP Series transmitters offer:
  • Small form factor for small/juvenile fish and salmon/smolt applications
  • Temperature sensing option available
  • CDMA coding for increased range and detection rates, especially in high noise/high traffic applications

Applications:

Suitable for all types of acoustic tracking, the Miniature MAP Series acoustic transmitters are particularly well suited for large scale fish tracking and positioning studies, due to their high noise immunity and collision resistance.

These tiny acoustic tags are ideal for studies where short burst interval and fine spatial resolution is required, and/or where hundreds of fish may congregate in the study area.
