註釋Describes a field study designed to establish seasonal habitat use relationships for adult lake sturgeon on the Groundhog River, north-eastern Ontario. The study was conducted in 1996 and examined lake sturgeon habitat use during spring and autumn seasons, representing high and low water conditions respectively. Fish were netted in randomly chosen locations in the study area, upstream and downstream of the Camus Rapids, and were measured, weighed, marked, and released. Catch, meristic, and habitat parameter data were entered into an electronic data base and analyzed using the SYSTAT program. Results presented include sturgeon length frequency distributions, substrate and depth preferences exhibited, and stream velocity preferences.
