Onsite Comments

Reported on IADNR social media by a citizen. Took photo of hundreds of dead fish caught on a brush snag in McLoud Run.

Fisheries response:

These are all gizzard shad and they came from the Cedar River. It is very common to see gizzard shad die offs after the ice goes out. We are on the northern edge of the gizzard shad and they are very sensitive to low oxygen conditions. This is only a fraction of the total population of gizzard shad and will not affect the fishery in any way. Catfish take advantage of this annual die off and gorge themselves this time of year. We have seen dead gizzard shad in Cedar Lake, Mohawk Park, Robins Lake and Prairie Park this spring.
