American Eel Migration

In 1998 and 1999, we identified the timing of out migration, swimming depth and migratory routes past the Moses-Saunders dam, for American eels

Northern Pikeminnow Telemetry

In early June 2021 CART tags were surgically implanted into 58 Northern Pikeminnow to help identify locations for targeted sampling of spawning fish for a selenium toxicology study in Lake Koocanusa (reservoir) in BC. This project was conducted in association with Minnow Environmental for Teck Coal. Biotactic was involved with designing the telemetry component of the study, tagging fish, training field staff on the use of acoustic and radio telemetry equipment and regularly analyzed sent tracking data to direct Minnow field staff to possible spawning locations for sampling.

Greater Redhorse Ecology

In 1997, we began studying greater redhorse (Moxostoma valenciennesi) spawning habitat, spawning behaviour, fecundity, egg and larval development, as well as post-spawn movements and habitat use. We continued this work into 2006 with a 6-year radiotracking and underwater videography study of redhorse in the Grand River.

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 …
