Mozingo Lake

City officials have called in the Missouri Department of Conservation to help identify the cause of a fish kill at Mozingo Lake. City Manager Greg McDanel said that signs currently point to a carp-related virus.

MARYVILLE, Mo. — Maryville officials are looking into the deaths of a large number of fish in Mozingo Lake.

The dead fish were discovered in the lake late last week.

“The fish kill at Mozingo is 100 percent carp to our knowledge, which is a high indication of a carp-related virus,” said City Manager Greg McDanel in an email.

McDanel said that Tory Mason, fisheries management biologist with the Missouri Department of Conservation, assisted city staff on Monday with collecting live fish for a pathologist examination to determine the cause. Mason said an initial pathology report showed there was no organ damage, indicating a virus.

“We had them sent off to pathology, and they send them to a lab in La Crosse, Wisconsin, and they’re on their way right now,” Mason told The Forum. “There is a specific koi virus that just affects carp that happens every now and then.”

Such a virus wouldn’t pose any threat to people though.

“No fish disease has ever transferred to a human,” Mason said. “Fish diseases kind of live in the water all the time anyway, they’re just kind of always there. And then stuff like this happens every now and then when … the stars align and environmental conditions are just perfect for certain situations.”

McDanel said city staff are working to clean up any remains.
