DNR Looks Into Spike in Dead Fish News | June 29, 2022 | 0 | by Morgan McCarthy The DNR is looking into a spike in dead fish in the Fox River and Green Bay. Researchers don’t have any answers yet, but say they’ve gotten a number of reports of dead fish washing-up along the shores. The first dead fish started washing-up about two weeks ago. DNR scientists say there’s nothing that stands-out from their tests just yet. They are hoping to collect more samples.
