First Install of 2021

The EU based Biomark team worked hard to install a new antenna ray in Italy at he end of January. 

This system was installed on river Toce, main tributary of the Lago Maggiore, to monitor marble trout and lake trout migration. The System will be managed by CNR IRSA (Italian Research Council) based in Pallanza (Italy).

HDPE Antenna

Biomark employs an exhaustive QC/QA process during production, assembly, and installation to ensure all components function according to required specifications and deliver optimal performance prior to leaving Biomark’s production facility.

Antenna Cable

Biomark offers antenna cables with underwater connectors in various lengths. Bare antenna and CAN Bus cable are available for purchase by the foot.

Remote Monitoring

The Master Controller is used to as the command, control and data collection center for a PIT tag monitoring system.

Nebraska Game and Parks Mussel Study

From Bryan Sweet, Fish and Wildlife Program Manager – North Platte State Fish Hatchery

Nebraska Game and Parks have been culturing and reintroducing native mussel back into the “wild” for a few years.  All mussels released are tagged to identify hatchery origin.  PIT Tags are used for a portion of the release to allow for recapture.  Locating the general area of the mussels with a Biomark BP Plus antenna worked well, but the pinpoint locating to allow them to be dug from the substrate was somewhat an issue in some streams. 

“Working with the folks at Biomark, we came up with a solution,” said Bryan Sweet.  After explaining the issue, a wand antenna was built that works in conjunction with the BP Plus portable antenna.  A selector switch allows the user to toggle between antennas to easily locate buried mussels.  The second antenna design was to build a dual coil BP Plus antenna; a second small antenna inside the standard antenna, again controlled with a switch.  “So far they have performed well, we have been able to dig all mussels located, whereas in the past only a percentage of the “hits” were located,” explained Sweet.

Our PIT Tags can be used to track just about any species out there. Biomark works hard to come up with the best monitoring solutions for your unique study. Talk with one of our Biomark experts to see what solutions we have for you!

NEWS RELEASE: Biomark Launches Open-Access, Sea Turtle Tagging Database

NEWS RELEASE: Biomark Launches Open-Access, Sea Turtle Tagging Database

Digital Infrastructure Seeks to Improve Global Collaboration and Insight on Migration Patterns and Health of Sea Turtles

BOISE, Idaho, June 16, 2020 – Biomark today announced the launch of a database that will further sea turtle research and conservation efforts where biologists and others in the conservation community can work collaboratively to exchange tagging and sighting information. The Sea Turtle Tagging Database was created in partnership with Loggerhead Marinelife Center, a nonprofit organization that promotes the conservation of ocean ecosystems with a special focus on threatened and endangered sea turtles.

The ability to identify and track individual sea turtles over many seasons and throughout their lifetime provides a wealth of knowledge about biology, behavior and movement. Biomark’s Passive Integrated Transponder (PIT) tags were developed as a reliable, life-long, and minimally intrusive technique to identify and track individual animals.

“Biomark has supplied PIT tags to the sea turtle community for many years,” said Brian Beckley, president, Biomark. “From these relationships, we have upgraded the technology to ensure they are sea turtle friendly, while reducing plastic waste and adding new features such as backlit displays to our handheld readers for nighttime nesting studies. We have built upon existing data collection technology to create this database, which is a natural extension in support of our customers. By making the database open access, we can increase the potential to positively impact sea turtle conservation efforts on a global scale.”

The value of a PIT tag is inherently linked to re-sight potential, which may occur beyond the geographic range of an individual project. Despite this, there is limited infrastructure for data sharing, and re-sighting data (along with biological data that are typically paired to it) may not be currently leveraged to their full potential.

The Database was created as a strategic conservation project built by leveraging existing Biomark software frameworks. “Working towards the recovery of endangered species is often dependent on collaboration and the availability of data from partners, especially when dealing with long-lived, migratory animals,” said Chris Beasley, director of biological services, Biomark. “The goal of the database is to enable researchers and organizations involved in sea turtle conservation to have access to a central storage location for their data, at no cost, where they control what data to share with others in the community,”

Collaborators at Loggerhead Marinelife Center ensured that the data points collected and features available would deliver value to others in the sea turtle community, including the ability to include a variety of tag types.

“We are grateful for the opportunity to collaborate with Biomark on this database,” said Dr. Justin Perrault, director of research, Loggerhead Marinelife Center. “By having a single, user-friendly, internationally cooperative system, we will be able to easily identify unknown individual sea turtles nesting on our beaches and using our local waters. We are excited for the potential collaborative nature of this project and how it will connect sea turtle researchers across the globe.”

The Database was introduced to more than 68 organizations involved in conservation and research efforts during a preview webinar in May 2020. Since then, improvements and updates have been made to the Database based upon user input. To date, there are 25 participants from three countries registered on the Database, which is accessible at no cost to participants in the sea turtle community. To learn more and register, visit:
