WHITLEY COUNTY, Ind. (WANE) — The Indiana Department of Natural Resources (DNR) is trying to determine what caused thousands of crappie to die at Loon Lake in Whitley County.

Photos shared to WANE 15 appear to show hundreds or more of the fish floating along the shore. It doesn’t appear any other type of fish was affected according to the DNR.

The DNR doesn’t know how many fish have died. It said DNR fisheries biologists collected fish and water samples at Loon Lake Wednesday.

Samples were provided yesterday afternoon to the Animal Disease Diagnostic Laboratory at Purdue University for testing regarding a cause.

DNR said, though, that it doesn’t believe the cause was a toxic event such as a chemical spill or release because no other small fish species were impacted.
