Second fish virus hits state
A second virus is sickening a growing number of fish in Wisconsin, but not as many as VHS a year ago.
The Department of Natural Resources says the new virus causes lympho-sarcoma in certain species, including muskies and northern pike.
Like VHS, the disease poses no threat to humans.
Sue Marcquenski, fish health expert, says the condition most likely spreads during spawning and other instances of fish-to-fish contact.
