MINISURT Sonotronics proudly introduces this new addition to available fisheries research technologies. This small, inexpensive, long life unit allows for tracking 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 miniSURT is its ability to save valuable field time by simplifying deployments thus reducing project costs.

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 miniSURT is its ability to save valuable field time by simplifying deployments thus reducing project costs. The miniSURT brings new features and options to the marketplace aiding in the continued development of fisheries research technologies. Applications Include: 1. Site fidelity studies 2. Spawning area detection 3. Animal attachment for social experiments 4. Simple positioning in array configurations 5. Gates for Active tracking boundaries 6. Towable: for area surveys The miniSURT allows simple mooring by using tie-wraps to connect to small rope. Transmitters within the units detection area will be logged to the on board memory along with date and time. The miniSURT may be configured in the field to allow frequency scanning for ACT coded transmitters, or use with rcode transmitters. The miniSURT is designed to allow mounting to an animal as a small (16mm diameter) expendable unit, as a remotely powered, cabled RS232 system, or as a standalone submersible receiver powered by a single AA lithium battery. miniSURTsoft The miniSURT is compatible with Sonotronics integrated software for communications with logging receivers – SURtool, SURsoft, and SURsoftDPC. SURtool or SURsoft may be used to set time and date, download data, configure detection frequency and many other options. The data processing center can be used to process and examine the data obtained from miniSURT’s, saving valuable time in sorting data. Features include examining data by transmitter, processing telemetry data, and viewing a graphic display of activity at a passive receiver.

Sonotronics proudly introduces the picoTag family. They represents the smallest acoustic transmitters in the Sonotronics product line, beginning at .6g in weight in water. These tiny transmitters will allow researchers to gain valuable information on small species never possible before. PT SERIES SUBMINIATURE TRANSMITTERS Range 300m – 750m+ Sonotronics proudly introduces the picoTag family. They represents the smallest acoustic transmitters in the Sonotronics product line, beginning at .6g in weight in water. These tiny transmitters will allow researchers to gain valuable information on small species never possible before. The PicoTags come standard in bullet shaped packaged shown in the photo. This packaging is more commonly used for internal implant or in cases where gluing the transmitter is appropriate. Slightly elongated packages are available that can contain small drill holes for external mount. Packaging changes result in changes in the weight and dimension specifications. Note that quoted ranges are when manual tracking. 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.

Coded High Power transmitters generate a unique aural sequence, as well as unique combinations of frequency and ping interval allowing detection by both passive and active receivers. The CHP series of transmitters provide maximum detection ranges for use with pelagic studies or in areas of high noise. CHP TRANSMITTERS Coded High Power transmitters generate a unique aural sequence, as well as unique combinations of frequency and ping interval allowing detection by both passive and active receivers. The CHP series of transmitters provide maximum detection ranges for use with pelagic studies or in areas of high noise. Coded High Powered Transmitters Notes Range is typical under good conditions, using a Sonotronics active receiver and directional hydrophone. Autonomy based on a ping rate of once per second. Extened lifetimes are available by cycling the transmitters, please contact Sonotronics for more details CHP transmitters are by default produced with flat ends and small holes for an external mount, but may be ordered with rounded ends for internal implant.

Acoustic Transmitters and Receivers -Sonotronics offers an array of tracking products built on the concept of an Integrated Tracking Approach – a method that permits interoperability between product types, as well as forward and backward compatibility. TRACKING PRODUCTS Sonotronics offers an array of tracking products built on the concept of an Integrated Tracking Approach – a method that permits interoperability between product types, as well as forward and backward compatibility. As an example, recently a transmitter used to tag a fish 14 years earlier was detected by a modern MANTRAK receiver, and recovered on a lake bottom by use of an Underwater Diver Receiver (UDR) used primarily for the recovery of tagged equipment. This flexibility and consistency protects your investment in equipment, and allows for collaboration between groups with different interests: many universities use Sonotronics passive tracking products for long term fisheries studies, while at the same institution, an engineering group uses equipment tracking transmitters to tag submerged electronics packages for later retrieval, and both groups use the same active tracking receivers to obtain real-time information on either fish or equipment location and associated telemetry. Although this equipment is highly compatible, there are some detailed differences that help in particular applications: for example Equipment Marking Transmitters (EMTs) the same internal electronics as passive tracking tags used in fisheries research, the EMTs are housed in rugged, brightly colored PVC, with large mounting holes allowing use of standard zip ties for easy attachment to equipment. Based on the application area, Sonotronics tacking products are divided into 3 areas: Active Tracking, Passive Tracking, and Equipment Tracking.

Our sonic telemetry project to determine the impact of the March 2008 High Flow Event on rainbow trout movement in Lees Ferry was a success because of your and your staff’s determination. We were able to deploy 90 transmitters in rainbow trout, the smallest of which was 157mm. We detected these tags before and after the flow with manual tracking and by using the submersible ultrasonic receivers. Interestingly, tagged trout did not displace downstream during the high flow. Thank you for your good humor and determination through this challenging project!” — Kara D Hilwig “Just wanted to drop an email to say thanks for all your help with our order! We’re really happy with the tags we received and have just begun our deployments. Thanks again! — Clemency” “… Furthermore I would like to inform you of an AWESOME recent finding. One of the 260cm female lemon sharks that was equipped with a Sonotronics 4 year transmitter was detected on our SUR array in Bimini for multiple days at the end of May this year. This shark was tagged in Bimini on May 19th 2007 and has not been detected since then. This shark was therefore at liberty for 2 years and the transmitter was still working on her return to Bimini – MASSIVE THANK YOU to you and all your team.” — Tristan Guttridge, PhD Student, University of Leeds, UK From another happy Sonotronics Customer – “Thank you for taking my call. I always appreciate how well I am treated by the team at Sonotronics and I look forward to doing more good work with you in the amazing years to come!” “Just received the USR-96 receiver … Looks to be working perfectly… just one more reason why your customer service is top-notch.” “We are honored. #customer service ALWAYS a pleasure”. – Dr. Yannis Papastamatiou, @Dr_Yannis The following information has been submitted by researchers who have used Sonotronics’ products in their studies.
