A research project studying Columbia River redband rainbow trout in Twin Lakes, Washington using Sonotronics acoustic transmitters COLUMBIA RIVER REDBAND TROUT STUDY Letter and pictures submitted by Mike Biggs, conductor of the study “A research project studying Columbia River redband rainbow trout in Twin Lakes, Washington, is being conducted this year. This study involves personnel from Washington State University (WSU) and the Colville Confederated Tribes (CCT). Introductions of nonnative fish and water quality conditions have created concerns for the trout fishery in Twin Lakes. In 2006, the CCT stocked a small number of ultrasonically tagged redband rainbow trout into Twin Lakes. Our goal was to determine the horizontal and vertical movements of these fish, and to relate their movements and habitat preferences to environmental conditions. Redband trout tracking demonstrated extensive daily movements along shorelines and across the lakes, with long periods of inactivity at night. Trout remained in a narrow band of habitat near the thermocline throughout the summer. Our preliminary results suggest improving water quality, to enhance summer trout habitat, may need to be addressed to provide a long-term trout fishery. We used depth and coded transmitters, and the MANTRAK to determine fish location and movements. We found the equipment very reliable and user friendly. Sonotronics service was excellent and provided timely delivery of products and customer satisfaction. We appreciate their cooperation and willingness to help us with our research.” Mike Biggs David Christensen Ed Shallenberger Barry Moore

The TH-2 provides a simple method for mobile active tracking: its small size and hydrodynamic shape allows for trolling at speeds up to 5 knots, while the long cable length minimizes the affect of engine and prop noise. Eyelets allow attachment of small weights or diving lures to ensure the hydrophone is kept at depth while trolling. This design, though simple, rivals more elaborate and expensive systems in actual field trials.

The DH-4 provides the greatest range and precision in locating transmitters from 30kHz to 100kHz. The parabolic reflector provide 16db of gain over a comparable omnidirectional hydrophone, and yields a calculated DI of nearly 25db, reducing the effect of environmental noise. The DH-4 is the primary hydrophone for manual/active tracking. MODEL DH-4 DIRECTIONAL HYDROPHONE The DH-4 provides the greatest range and precision in locating transmitters from 30kHz to 100kHz.

Sonotronics temperature telemetry transmitters transmit their current temperature by varying the pulse interval time between pings CTT TRANSMITTERS – CODED TEMPERATURE TELEMETRY Sonotronics temperature telemetry transmitters transmit their current temperature by varying the pulse interval time between pings. For example, a tag at 0 deg Celsius may have an interval time of 700ms, and at 25 deg celsius it may have a pulse interval time of 1450ms. Temperature tag instruction sheets are sent with temperature tags. The temperature transmitters have an accuracy of +/-2 deg C and a resolution of.5 deg C. The transmitters can be user calibrated for accuracies greater than +/- 2 deg C. Temperature Telemetry Transmitters CTT: Range up to 1km+ Notes The typical rule of thumb is to use transmitters that have a weight in water that is 1.5 – 2% of the fish weight in air. Weight in O2 (air) is put only as additional reference. -E is the extension denoting external mount, -I denotes internal implant. You must specify internal or external when ordering transmitters.
