fish kill

Fish kill events in Minnesota are widespread, and may provide clues about greater ecosystem-level issues such as Viral Hemorrhagic Septicemia virus (VHSv), water quality degradation, climate change, and invasive species. 

Reporting these fish kill events is an easy and effective way to do your part to help protect Minnesota waters. The online, user-friendly database is available now at It simply asks for the date, the location of the fish kill, and other basic information of any fish kill you observe. Once reported, fish kills are triaged and, if appropriate, trained biologists and students will collect samples to diagnose the cause of mortality. Do your part to protect our waters by reporting fish kill events that you see.
