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.
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.
Black Redhorse Ontogeny
Adult Black Redhorse (Moxostoma duquesnei), were seined from the Grand River, Ontario and artificially spawned in May 2007 and May 2008. Eggs hatched after 9-16 days at a mean temperature of 20° C, and after 11 – 25 days at a mean temperature of 17° C.
Habitat Creation and Monitoring
In 1999, Biotactic was retained by the City of Kitchener, to help develop spawning and nursery areas for warmwater fishes in ponds at the Stanley Park Optimists Natural Area.
Lake Mead Razorback Sucker Telemetry
In December 2004, December 2005, December 2008, February 2010, and January 2011 Biotactic assisted Bio-West (Utah) with the set-up of a combined
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.
