Radio Telemetry Studies

In September of 2005 RTA, in conjunction with other consultants, initiated a multi-year brown trout movement study in Rush Creek , the largest tributary to Mono Lake . The study has two primary objectives:

1. Better understand seasonal movements and habitat preference of brown trout throughout Rush Creek, with an emphasis on over-wintering habitat.
   
2. Document seasonal movement of larger brown trout within the Mono Gate One Return Ditch (MGORD) – the 1.2 mile channelized reach immediately downstream of Grant Reservoir.

To meet project objectives, radio tracking of tagged fish required using both a fixed receiving station and a manual receiver. The project utilized Lotek Wireless equipment, including three sizes of radio tags which were surgically implanted in selected brown trout.

RTA is fully trained and experienced in the following aspects of implementing a radio telemetry study:

1. Surgical implanting of tags following procedures developed by D.A. Schmetterling
2. Set-up and operation of a fixed antenna array and receiving station.
3. Programming and data downloading of Lotek's SRX 400A W7A fixed-station receiver/data logger.
4. Programming and use of Lotek's SRX 400W5XG mobile receiver.
5. Interpretation and synthesis of movement data.
