Viewers were so concerned they called FOX 2.
"I eat fish out of this river. I fish there. My nieces and nephews fish out of this river and ate out of this river," said Guy Cason. "I'm concerned. I'm concerned about their well-being."
The Michigan Department of Natural Resources says this is a natural occurrence called a "fish die off".
The fish are called "gizzard shad". They are a weak species that easily dies off in cold weather.
It's likely they were dead under the ice for some time.
Here's the bad news. We're told it's up to the property owner to clean up the dead fish. Source
