The Anishinabek/Ontario Fisheries Resource Centre (A/OFRC), in partnership with Michipicoten First Nation, the Ontario Ministry of Natural Resources, Natural Resource Solutions Inc., and Brookfield Renewable Energy Partners, conducted a Lake Sturgeon spawning survey and radio telemetry study from June 9 to July 31, 2014. Water temperatures during this time ranged from 11°C to 18°C, however there was a large amount of thermal variation depending on the location where water temperature was recorded.
This was the third consecutive year that this study was undertaken and a total of nine Lake Sturgeon have been radio tagged to date. Five of the nine radio tagged Lake Sturgeon ascended the Michipicoten River to Scott Falls Generating Station and remained there for several weeks while water temperatures were optimal for spawning. Two additional Lake Sturgeon entered the Michipicoten River during the study period; however their movements were restricted to the lower portion of the Michipicoten River below highway 17. In addition to the two base station receivers that were already installed on the Michipicoten River, an additional base station receiver was installed this year to remotely monitor Lake Sturgeon movements throughout the year.
The A/OFRC would like to thank Michipicoten First Nation band members Zach Day-Andre and Dominic Chasse for their assistance throughout this project.
