Why is fish migration in the Thames River a concern?
A variety of migrating species of fish move up and down the river over the seasons. The time of peak movement is from mid March to late June when some species move upstream to spawn. Healthy fish stocks are a reflection of a healthy river and by the same token a healthy environment for our city. The Thames has over 90 species of fish, making it one of the most diverse rivers in Southern Ontario. Fish, their movement and their habitat, is protected under legislation administered by the Ministry of Natural Resources (MNR) and the Department of Fisheries and Oceans (DFO).
