MN DNR Detroit Lakes Fishery Completes Long, but Successful Walleye Egg Take

April 28, 2021 News -- KRJB-KRJM-KKCQ R & J Outdoors Show 0

Detroit Lakes, MN — The Minnesota Department of Natural Resources biologists recently wrapped up their annual spring walleye egg take at Dutton Locks in Detroit Lakes. Last year, the DNR fisheries biologists did not collect walleye eggs because of COVID-related considerations and now this year the procedures were re-engineered to minimize close contact among employees. Despite the early ice out, the temps never warmed up significantly after the ice was gone, which Detroit Lakes Area Fisheries Supervisor Nathan Olson said made for a long and drawn-out process.

Once the DNR collects the eggs, they are taken one of the various hatcheries across the state to be hatched and then stocked into area lakes this spring.

The Detroit Lakes Hatchery usually collects around 60 million eggs each year and about 70% of those successfully hatch into fry. Olson notes that some larger lakes, such as Height of Land Lake, will be stocked with as many as 3 million fry every year whereas most smaller area lakes take in about 500,000. However, only about 1 or 2% of stocked fry typically survive after being stocked.
