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.
Greater Redhorse Ecology
In 1997, we began studying greater redhorse (Moxostoma valenciennesi) spawning habitat, spawning behaviour, fecundity, egg and larval development, as well as post-spawn movements and habitat use. We continued this work into 2006 with a 6-year radiotracking and underwater videography study of redhorse in the Grand River.
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
Integrated Wetland Management- Lake Chubsucker
Our initial contract with Environment Canada (EC) / Canadian Wildlife Service (CWS) involved relocation of native fish and disposal of non-native invasive species during a planned drawdown of the St. Clair National Wildlife Area
Lake Niapenco Sport Fish Population Estimates
The Niagara Peninsula Conservation Authority (NPCA) contracted Biotactic to conduct a fish community and population study at the Binbrook Conservation Area, (Lake Niapenco), Binbrook, Ontario. The main objective of the project was to perform
