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.
Grand River Smallmouth Bass
Mobility of tournament-caught and released smallmouth bass Micropterus dolomieu was monitored in the Grand River, Ontario, between 1995 and 1999 using radiotelemetry and mark–recapture.
Welland River Siphon (Aquaduct): Impacts of Flow Reversal
In February 2001, Biotactic was contracted by the Niagara Peninsula Conservation Authority to investigate the impact of the Old Welland Canal (OWC) siphon complex on fish migration. The siphon complex
Lake Mead Razorback Sucker Telemetry
In December 2004, December 2005, December 2008, February 2010, and January 2011 Biotactic assisted Bio-West (Utah) with the set-up of a combined
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.
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 …
