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.
Northern Pike Telemetry and Passage Monitoring
Radio transmitters were surgically implanted in the body cavity of ten northern pike between 502 mm TL and 752 mm TL in March 2003 to assess fish passage at the Port Davidson Weir. Fish were released downstream from the fish bypass channel, and tracking began immediately using mobile
Blue Sucker Tracking
In October 2004 we implanted thirty Texas state endangered blue suckers (Cycleptus elongatus) with radio transmitters that we (Bio-West, Austin and Biotactic) monitored continuously
Black Redhorse Ecology
In October 2007 a large pool in the Grand River near Kitchener, Ontario was sampled using seine nets for adult black

In May 2013 we assisted Stantec Ltd. with a walleye, northern pike and white sucker spawning survey in a small tributary
Restoring Walleye Migration in the Shebeshekong River
In 2017 we restored migration routes for Walleye at a set of rapids and a waterfall that had been damaged by historic logging operations in the Shebeshekong River which is a tributary to Georgian
Fisheries Offsets and Compensation- Bruce Power
Biotactic devised and developed a Before-After-Control-Impact (BACI) study for the Bruce Power Nuclear Generating Station to offset and compensate for fisheries impacts associated with nuclear
