Michigan officials say a fish virus may have contributed to a June fish kill of 300 to 500 common carp in
The state Department of Natural Resources announced Wednesday that samples taken from the lake in Livingston and Oakland counties detected the presence of koi herpesvirus.
State officials say it's the first time the virus has been found in wild fish samples in Michigan. It was detected in a private koi pond near Grand Rapids in 2003.
The DNR says the virus has been seen before in large-scale common carp die-offs in Ontario, Canada, in 2007 and 2008.
The virus affects common carp, goldfish and koi. The state says there are no human health effects.
