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 …
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 …
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
Seasonal Changes in Movement and Habitat of Largemouth Bass
The main objective of this study is to provide valuable baseline data, which are essential for monitoring and tracking changes in the lake.
Rainbow Trout Migration Patterns in the Saugeen River Watershed
The Truax Dam was removed in August 2019. Future post-removal phases of this study will provide data that will be compared to baseline information to assess the impact of the removal of this barrier on the Saugeen River rainbow trout population.
