MADISON (WKOW) – Wisconsin wildlife officials are trying a new menu for the muskies at the Wild Rose Fish Hatchery.
Department of Natural Resources fishery workers have already separated the hatchery's muskies into two groups and will feed them different things. One group is being fed a traditional diet of minnows and zooplankton. The other group will get manufactured fish food and then minnows for the last 60 days before they are stocked.
In order to tell the fish apart, the agency's staff will mark the groups before they are stocked so they can assess survival rates.
DNR Fisheries Director Mike Staggs says the agency can save up to 30 percent of the cost of raising muskies if they start them on manufactured food.
Researchers want to see if the fish grow and survive before the practice becomes standard at all hatcheries.
