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.
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.
Fish Surgery and Telemetry Services
Fish Surgery and Telemetry ServicesSurgeryWe 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 methodologies relevant …
Razorback Sucker Telemetry
Biotactic assisted Bio-West (Utah) with the set-up of a combined sonic and radio-telemetry project of federally endangered razorback suckers
Brown Trout in the Kananaskis River
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 Telemetry
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
Spotted Gar Habitat Utilization
In May of 2007 we initiated a radio telemetry project for spotted gar in Rondeau Bay on Lake Erie
