COWICHAN LAKE CUTTHROAT TROUT PROJECT INFO

Adfluvial cutthroat trout are the focal fishery in most of the large lakes on Vancouver Island, including Cowichan Lake, yet we have a poor understanding of their natural mortality and spatial ecology, and the degree to which fisheries regulations are appropriate or effective. With support from the Habitat Conservation Trust Fund and the Freshwater Fisheries Society of B.C., Kintama and the B.C. Ministry of Forests, Lands, Natural Resource Operations and Rural Development (FLNRORD) are conducting a multi-year study to partition fishing mortality from natural mortality, provide insights into cutthroat trout life history and spatial ecology, and promote the successful long-term management of cutthroat trout in Cowichan Lake. We tagged cutthroat trout with acoustic transmitters and high-reward Floy T-bar anchor tags in 2019 and 2020. The animations show the movement of these fish up to the last data upload. They will be tracked using acoustic receivers deployed lake-wide for up to three years with data uploads occurring twice a year. We tagged additional fish with high-reward tags and anglers are asked to remove the Floy tags and submit them to the ministry office at 2080A Labieux Rd in Nanaimo for a $100 reward (or photograph and email to Brendan.Anderson@gov.bc.ca).

Dynamic Animator for fish tagged in 2019

We tagged 42 cutthroat trout in October 2019 with acoustic transmitters and high-reward Floy T-bar anchor tags. The animation shows the movement of these fish up to the last data upload in September 2021. Access the animation here.
