State investigating reports of dead fish in river
ROCKFORD (AP) — State officials say they are checking out reports from people who say they've spotted hundreds of dead fish in the Rock River.
The Rockford Register Star reports that a spokesman for the Illinois Department of Natural Resources is dispatching a state biologist to the river to look for evidence of a fish kill.
Experts say fish kills can be caused by a number of things, including the flow of industrial or agricultural waste into the river. Also, the cold weather can kill certain kinds of fish and fish also can be trapped in small pools under the ice and die and after the ice melts their bodies surface.
One area man says he counted dozens of dead bluegill, catfish, carp and other kinds of fish floating in the river.
