In July 2021 and 2022, Biotactic staff travelled to Hope Bay, Nunavut to build fish fences equipped with 2 BRAVO G3 fish monitoring and counting systems. Conducted in association with Minnow Environmental for Agnico Eagle Gold, this project is designed to measure the effectiveness of a rocky ramp fishway, or boulder garden, for restoring access for migratory Arctic Char and Lake Trout to and from Robert’s Lake. Movement will be monitored for several months and passage metrics will be calculated to determine passage success relative to baseline studies.
Sulphur Springs: Chemical Barriers to Fish Movement
Several cold water sulphur springs flow into tributaries of the Welland River on the Niagara Peninsula. Sulphur spring water temperature
Grand River Smallmouth Bass
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.
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
Dam Effects on Benthic Fishes
The biology, microhabitat use and migratory behaviour of greenside darters (Etheostoma blennioides) was studied at the Mannheim Weir
Black Redhorse Habitat Preferences
We have been working in conjunction with Fisheries and Oceans Canada to study egg development, early life history
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.
Silver Shiner Size-Class Structure, Habitat Utilization, Movement and Persistence in an Urbanized Fragment of a Great Lakes Tributary
Silver Shiners were captured and habitat was characterized from 38 locations in the Grand River during the summer and autumn of 2013
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.
Rainbow Trout Passage at a Nature-Like Fishway, Beaver River, Ontario
Rainbow Trout (Oncorhynchus mykiss) were monitored over two consecutive vernal migration periods at a nature-like fishway on the Beaver River, Ontario to assess attraction efficiency, passage
