The DNR is about to start a 3 week study on the fish population in a Cheboygan County Lake.
The study is specifically taking a look at the juvenile fish population in Black Lake.
DNR officers will use a tag-and-recapture technique by marking all the sturgeon they catch, then looking at the ratio of marked to unmarked fish from a later catch to figure out the population size.
This information will help fisheries adjust future stocking levels, and figure out population goals.
Lake sturgeon rehabilitation has been ongoing in the Black River and Black Lake for more than a decade.
