Fish sponsored by the public (Lake Huron Fishing Club, Steeldreams, Bruce Power LP) will be tracked from November 18 2024 until March 2025 for the fall/winter monitoring period
Spring 2024 Radiotelemetry
Fish sponsored by the public (Kollen family, Lake Huron Fishing Club, Steeldreams, Bruce Power LP) will be tracked from April 22 until early June during the spring 2024 monitoring period
Public Participation Opportunities
The Truax Dam, which was located on the Saugeen River in Walkerton, Ontario, for over a century was identified as a barrier to the upstream movement of the entire fish community while it simultaneously created a 1.5km headpond and interrupted natural biophysical processes within the river.
Videographic Surveys Saugeen River
Biotactic has been performing videographic surveys of fish passage at the Maple Hill dam fishway as well as within Otter Creek since 2018. Seasonal surveys are conducted using BRAVO M2 systems and the species, direction of movement, time, and condition of each unique fish is transcribed from recorded video.
Salmonid Redd Counts in the Saugeen River
Biotactic has been performing redd counts within the Saugeen River watershed since 2018. Surveys are conducted by trained staff in the Spring during the Rainbow Trout spawning period as well as in the Fall during the Chinook Salmon spawning period through a combination of wading and aerial drone videography.
Electrofishing Surveys to Determine Fish Community Biomass
Biotactic established twenty-two long term monitoring sites (66 sampling subsections) across the Saugeen River watershed within which annual biomass electrofishing surveys are performed to monitor the change in the fish community as a function of the removal of the Truax dam in Walkerton, Ontario, as part of a fisheries offset and compensation project.
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.
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
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
