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.
Effects of Increased Silt Load
Rock bass (Ambloplites rupestris) are a widespread centrarchid species with both riverine and lacustrine populations. After precipitation evens, rivers often carry elevated silt loads, where as lakes generally remain
Swimming in Turbulent Flows
We have installed and operated cameras that stream fish movement inside fishways, onto the internet since 2007. In 1997, 1998 and 1999, we used underwater videography to monitor fish behaviour
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
Biotactic Fisheries Research & Monitoring – Biotactic Inc.
We began using underwater videography to monitor fish back in 1989 and things have changed a lot since then. Using our invaluable experience, we design, build and supply fish monitoring and fish counting systems.
