Little is known about the spatial biology and seasonal movement behaviour of bowfin (Amia calva), despite the fact that it is the last living member of the Amiiformes and effectively a living fossil. In the summer of 2013, we surgically implanted 10 bowfin captured in Toronto Harbour with acoustic telemetry tags. Using a stationary acoustic telemetry array that covered most of the harbour, the residency and movement patterns of bowfin were tracked from their release until April 2014. The results of this study will provide us with a first look at the seasonal habitat-preference, home range and activity level of this seldom studied fish.
