Seasonal utilization distributions (UD) of lake sturgeon in the Buffalo Harbor area for summer and fall seasons, 2017–2018. Seasonal UDs were calculated for 57 individual lake sturgeon using a Brownian bridge movement model. Cell size was set to 30m2 and breaks were set at 5-h intervals. Resulting UDs were then averaged across all individuals. Position estimates were derived from a Vemco Positioning system [10]
