In July 2021 and 2022, Biotactic staff travelled to Hope Bay, Nunavut to build fish fences equipped with 2 BRAVO G3 fish monitoring and counting systems. Conducted in association with Minnow Environmental for Agnico Eagle Gold, this project is designed to measure the effectiveness of a rocky ramp fishway, or boulder garden, for restoring access for migratory Arctic Char and Lake Trout to and from Robert’s Lake. Movement will be monitored for several months and passage metrics will be calculated to determine passage success relative to baseline studies.
Videographic Surveys Saugeen River
Biotactic has been performing videographic surveys of fish passage at the Maple Hill dam fishway as well as within Otter Creek since 2018. Seasonal surveys are conducted using BRAVO M2 systems and the species, direction of movement, time, and condition of each unique fish is transcribed from recorded video.

Fish Movement in the Welland River Watershed
Starting in 2001 Biotactic, with the Niagara Peninsula Conservation Authority (NPCA) and Niagara Restoration Council, has monitored the diversity and relative abundance of fishes in the Welland River and Oswego Creek using various active sampling techniques, radio-telemetry and a long-term publicly assisted mark-recapture study.
BRAVO Underwater Videography
BRAVO Network Biotactic Research And Videography ObservatoriesWe began using underwater videography to monitor fish back in 1989 and things have changed a lot since then. Using our invaluable experience, we now design, build and supply cabled underwater fish and wildlife monitoring and counting systems that are ideal for monitoring fishways (for example see Node 10) and any other artificial or …
