- Wisconsin fisheries staff want to know whether a different diet will help muskies survive better.
They're experimenting with a new menu for muskies at the Wild Rose Fish Hatchery in central Wisconsin.
Fishery workers have separated the hatchery's muskies into two groups.
One group is being fed a traditional diet of zooplankton and minnows.
The other group is getting manufactured fish food and then minnows for the last 60 days before they're stocked.
Agency staff will mark the groups to tell them apart before they're stocked.
That will let them assess survival rates.
The DNR can save up to 30 percent of the cost of raising muskies by starting them on manufactured food.
Researchers want to see if the fish grow and survive before the practice becomes standard at all hatcheries.
