Understanding the distribution and presence of different cyanotoxins in Ontario waters

Cyanobacteria, algae that form on the surface of nutrient-rich waters, can produce an array of toxins. Accurately measuring these toxins in waterbodies is crucial because they can pose risks to human health and other biological communities. Unfortunately, monitoring and research of these toxins has focused almost exclusively on one particular compound—microcystins. Cyanobacteria, however, can also

Evaluating stationary hydroacoustics for determining fish movement and abundance

Little is known about the large-scale movement patterns of Great Lakes fishes. Though it is understood that large migrations of fish typically occur along regions of Lake Superior during spawning events, the timing and potential drivers of these events are not well understood. Better understanding the timing and drivers of these events is important for more effective management of these fisheries. …

Black Bay Walleye Acoustic Telemetry

Located on the north shore of Lake Superior, Black Bay historically supported a robust commercial and recreational fishery for walleye (Sander vitreus). Unfortunately, the walleye population rapidly declined in the 1960s because of a combination of habitat loss and commercial over-fishing. In response, managers closed the fishery in the northern part of Black Bay to allow the population to recover. …
