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.

Acoustic telemetry resources, papers, and information on how to choose transmitters for your study. Resources Depth or Temperature Telemetry Product Comparison A datasheet which shows the comparison of Sonotronics products associated with Depth and Temperature Telemetry Understanding Sonotronics Unique Pinger ID Algorithm A document which explains the algorithm used by Sonotronics for the unique ID of transmitters. Custom transmitter labels Email us to customize the labels in your transmitters. This allows you to leave a visible message that shows through the clear wall of the transmitter telling anglers, etc. where they can send the transmitters if found How to choose transmitters for your study Consider the following when choosing the appropriate transmitter. Size – The commonly used rule is 1.5% – 2% of the animal weight in air is maximum allowable transmitter weight in water . Exceptions to this rule are sometimes made by biologists in the case of robust species, crustaceans, and other animals that are determined to be able to hold a larger transmitter. Lifetime – It is recommended that a lifetime that is 125% of the actual length of the study is used. This allows extra room at the end of the study, and helps guarantee a high output from the transmitters throughout the study. Range – It is recommended that the highest output transmitter available that fits in the necessary lifetime and size categories be used. This guarantees greatest ranges in both automatic and manual tracking. Keep in mind that a number of factors in the environment can limit range. Telemetry – There are a number of telemetry options available on Sonotronics transmitters. Temperature, acceleration (used for feeding and mortality), depth, and tilt. These options are chosen based upon the data desired in the study. The Don L. Brumbaugh Memorial Equipment Scholarship The Sonotronics’ Equipment Scholarship, established in 2005, commemorates Donald L. Brumbaugh’s pioneering work in the development of fisheries and wildlife biotelemetry technologies. The scholarship is designed to aid students in fisheries research projects. Read more…

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.

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.

The ETN, together with industry (being Thelma Biotel, Sonotronics, and Lotek), have worked on the development of new open tag protocols, which are available for all telemetry users across the world. As stated in the compatibility note , it is now clear that encrypted protocols in acoustic telemetry should be avoided by all means. To move forward towards a much-needed pan-European collaborative network that could provide relevant information in support of decision-making processes related to conservation and management, compatibility between brands and agreements on transmission protocols and ID allocation are imperative. Therefore, the ETN, together with industry (being Thelma Biotel, Sonotronics, and Lotek), have worked on the development of new open tag protocols, which are available for all telemetry users across the world - this technology is NOT restricted to Europe. This resulted in two robust and energy-efficient transmission protocols aimed for the aquatic research community, being OPi and OPs, for ID and sensor tags respectively. The Open Protocol: OPi supports over 1 million unique IDs, while OPs supports over 64 000 unique IDs with up to 4096 data points resolution. Both protocols are short and effective to reduce issues with transmission collisions. The protocols are available for all interested manufacturers after agreeing with the terms of references. Opening the infrastructure networks of acoustic telemetry to all manufacturers of different types of sensors and tags will drive innovation, and boost availability of new solutions for future research. The Manufacturers handed over OP to the ETN, who assigned the Flanders Marine institute as a third party to control the ID allocation related to these protocols.
