SUR SUBMERSIBLE ULTRASONIC RECEIVER Sonotronics proudly introduces this new addition to available fisheries research technologies. This rugged, inexpensive, long life unit allows for detection of fish passage within its detection area. Strings, arrays, or individual receivers can be utilized depending on the resolution of detection desired in the study. One of the main principles behind the SUR is its ability to save valuable field time, potentially reducing project costs. The SUR brings new features and options to the marketplace aiding in the continued development of fisheries research technologies. Features 1. Frequency scanning – large numbers of unique transmitters 2. Ability to detect transmitters also used in manual tracking 3. Backwards compatibility with all Sonotronics transmitters 4. Ability to determine presence of data in the SUR without retrieving the receiver – “ping and response” 5. Ability to interface with a variety of communication systems: cellular and wireless 6. Long battery life: 8 months with typical configuration 7. Saves valuable time in the field reducing manual tracking hours The SUR is simply moored using the eye bolt on the bottom. Its natural buoyancy will keep the unit upright in the water column. Transmitters within the units detection area will be logged to the on board memory along with date and time. The SUR can be interrogated remotely for the presence of data, allowing it to be left alone with no data hits. Data is then downloaded via the serial port. The SUR is a stand-alone submersed unit which allows for detection and logging of the same transmitters used in manual tracking, including any Sonotronics past or present transmitters. The SUR is a scanning receiver allowing for transmitters on different frequencies to be logged, also allowing exclusive channels for specialty transmitters. The SUR is designed to interface with a variety of communication systems allowing for greater system flexibility and reduce field time. The CUB cellular uplink buoy allows for real time cell phone communication upon animal passage. Radio uplink buoys are now available allowing for remote data download and configuration. 900MHz and 2.4GHz (internationally approved) bands are available. SURsoft Free software for communications with the SUR’s – SURsoft. SURsoft can be used to set time and date, download data, program frequency scanning maps, and many other options. SURsoft now includes a data processing module (As shown on the figure). The data processing center can be used to process and examine the data obtained from SUR’s, saving valuable time in sorting data. Features include examining data by transmitter, processing telemetry data, and viewing a graphic display of activity at an SUR. The SUR’s available ping and response transponding allows researchers to “ping down” to the SUR on a separate frequency, asking it to “ping up” its status, which can be detected with a manual tracking receiver. The SUR transmits a ping sequence related to the presence/absence of data in its flash memory. On many projects, this can save field time as the units do not need to be retrieved to determine data presence. Accessories, Options, Ordering SUR-3BT : This is a stand- alone device consisting of a battery system, microprocessor, 2Mb of flash memory, real time clock, hydrophone, ultrasonic receiver, and Bluetooth connectivity for wireless, high- speed downloads and configuration. SIT-01 : This is the SUR Interrogator Transmitter. This a 60kHz transmitter with a specific pulse rate used to interrogate SUR’s for the presence of data. Only one SIT is needed to service multiple SUR’s. SURBAT : This is a replacement battery for an SUR Links: Datasheets SUR SURsoft SUR-3BT Manuals SUR SUR-22BLE Software Downloads VIDEOS

Sonotronics’ depth telemetry transmitters transmit their depth by varying the pulse interval time between pings. For example, a tag at 0psi at the surface may have an interval time of 650ms, and a full scale pressure of 100psi with a corresponding interval time of 2050ms. Depth transmitters come in 50, 100, 200, 300, and 500psi models. The accuracy of these transmitters is +/- 2% of full scale.

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

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.
