Leveraging Biomark Litz Cord Antenna Systems to Evaluate Fish Passage and Movement

Leveraging Biomark Litz Cord Antenna Systems to Evaluate Fish Passage and Movement

Biomark’s Biological Services team is leveraging Biomark Litz Cord Antenna Systems to evaluate fish passage and movement in side channels of the Lemhi River.

Field Biologist Mike Hall explained, “We are using these antennas in a recently completed restoration area as well as an area where restoration efforts are slated to begin in the next year or two.”

This will allow the team a great opportunity to gather pre and post restoration data.

The Litz cord antenna systems are set up in “pass-through” orientation allowing the biologists to effectively detect fishes in all portions of the water column at both high and low flows.

We are also utilizing submersible antennas in the main channel of the river for monitoring purposes.

Advanced Analytics for Fish & Habitat Relationships Webinar Recording

Understanding what features comprise high quality habitat is critical to endangered species recovery. Ecological datasets often incorporate nonlinear relationships, correlated variables, and substantial noise: all of which make establishing the relationship between species and their habitat challenging. Biomark researchers have developed advanced analytical tools that pair abundance and habitat characteristics data to define these elusive relationships. Leveraging a suite of modeling techniques such as habitat suitability (HSI), habitat preference, and quantile random forest (QRF) allow for a comprehensive approach to evaluating habitat quantity and quality.

This webinar recording showcases how generating near real-time estimates of carrying capacity by species and life stage, can provide actionable information for habitat restoration and recovery planning.

BOISE, Idaho, March 9, 2020 – Biomark today announced the publication of a research study designed to estimate the carrying capacity for juvenile salmon using quantile random forest models, which demonstrate the viability of guiding habitat restoration efforts that could de-list salmon from the endangered species list.

The research study, entitled “Estimating Carrying Capacity for Juvenile Salmon using Quantile Random Forest Models,” [manuscript number ECS20-0483.R1]  was published in Ecosphere, a journal of ecological science and interdisciplinary studies relating to ecology.  

Endangered salmon populations in the Pacific Northwest are facing the loss or degradation of their stream habitat throughout the interior Columbia Basin. Recent published studies have suggested that their recovery may be constrained by a lack of capacity or a lack of high-quality habitat. However, understanding what habitat characteristics define high-quality habitat is confounded by large, convoluted datasets with non-linear relationships, correlated variables and outliers.

“In our research study, a quantile random forest (QRF) model was developed using fish and habitat data from seven watersheds in the Columbia River Basin to estimate life-stage specific habitat-based carrying capacity. This new approach leveraged nearly a decade of detailed habitat data from the Columbia Habitat and Monitoring Program (CHaMP) to determine habitat characteristics that best explain salmon abundance and density, which is used to predict contemporary capacity at those sites and extrapolated throughout the basin,” said primary author Kevin See, Senior Biometrician, Biomark.

While stream habitat rehabilitation actions are taking place in many watersheds within the Columbia River Basin, the potential improvements to carrying capacity for an individual action may not be reflected in observed fish abundances for many years. This research study demonstrates one way to infer the effect restorative actions have in near real time by focusing on how habitat restoration translates  directly to fish capacity. Historically, the response to capacity changes by fish populations may take years or even decades to manifest, making the evaluation of those actions difficult.

As more ecological datasets become available, and the ability to sample large areas of habitat becomes more feasible (e.g., aerial imagery, LiDAR), the QRF framework demonstrated in this study provides a robust structure for using a capacity-based approach to prioritization, implementation and evaluation of habitat rehabilitation actions.

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.
