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.
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
In December 2004, December 2005, December 2008, February 2010, and January 2011 Biotactic assisted Bio-West (Utah) with the set-up of a combined
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.
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 Network Biotactic Research And Videography Observatories We 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 systems that are ideal for monitoring fishways (for example see Node 10) and any other artificial or natural …
Fish Surgery and Telemetry Services Surgery We regularly perform professional fish surgery and have developed, tested and published multiple descriptions of surgical procedures for implantation of biotelemetry transmitters, electrodes, and vascular flow probes in freshwater and marine fish species. We have invented custom surgical tools for specific research applications, and examined effects of various surgical techniques, wound-closure, and infection control …
We used radio-telemetry to investigate detailed movement and summer habitat of brown trout Salmo trutta (size range 157 – 488 mm TL, n = 18) in the Kananaskis River, Alberta. Flows in the Kananaskis River respond to pulsed daily discharge from an upstream hydroelectric generating facility (range 0.15 – 25 m3.s-1). Wetted area available for brown trout doubled during periods of high flow. Fluctuating river levels did not appear to influence the degree to which brown trout moved within the study site. However, there was evidence that brown trout used cover and pools more as discharge increased.
Coral Trout were tagged and tracked with ultrasonic transmitters over 81 days at an intra-lagoonal location at One Tree Island (OTI), Great Barrier Reef, Australia
In May of 2007 we initiated a radio telemetry project for spotted gar in Rondeau Bay on Lake Erie
