From July 10 to July 27, gill nets made specifically for capturing sturgeon will be set and marked with buoys Monday through Thursday of each week. Staff will check the nets every 1-2 hours during the day. Nets will be set each day and marked with staff buoys. Nets will be removed at the end of the day and will not be left in the lake overnight. Once captured, lake sturgeon will be measured and tagged with a Passive Integrated Transponder tag if they are not already tagged. The PIT tag allows staff to uniquely identify individual fish when they are recaptured and provides data needed to calculate a population estimate. Some lake sturgeon under 40” will have a small portion of a fin removed so the age of the fish can be determined. This will allow staff to evaluate growth of both stocked and naturally produced lake sturgeon in Black Lake.
The DNR asks the public to be on the lookout for these buoys and avoid them while boating on Black Lake during this survey.
