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
BRAVO Network Biotactic Research And Videography Observatory We 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 systems that are ideal for monitoring fishways (for example see Node 10) and any other artificial or natural …
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 (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
Passage efficiency of radiotagged rainbow trout at the Maple Hill fishway was 20 %. Based on our professional opinion, coupled with radiotelemetric data and underwater videography, it is highly likely that the measured
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
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
In September 1999 and April 2002, Biotactic Inc. was contracted by The Dow Chemical Company to examine a vertical-slot fishway
A Denil fishway in Dunnville, Ontario was built to provide upstream passage for walleye Stizostedion vitreum from Lake Erie to the Grand River. Modest numbers of walleye have been observed to use this fishway.
Two Denil fishways on the Grand River, Ontario, have been monitored for activity by several dozen fish species annually since 1994
