The DNS is calling it a “major fish health crisis.”

Two freshwater drum fish in the Lake Winnebago Chain of Lakes have tested positive in preliminary analysis for VHS said a spokesperson for the DNR.

“Yesterday (Friday) was the first day of boating,” said Steve Collier, a lock tender at Menasha. “I came down on the 4 (p.m.) to midnight shift and I noticed all the dead fish floating around. I’d never seen that before, especially at this time of the year. I couldn’t believe how many there were.”

The DNR is urging anglers to take caution so they don’t further spread the disease — like draining boats before leaving the water, cleaning off weeds and mud and not moving live fish.
