Cleaner water could have negative impacts on certain types of fish in Lake Erie, a study by researchers at Ohio State and other universities found.

Stuart Ludsin, an Ohio State professor of ecology and co-author of the study, calls supervising nutrient levels in Lake Erie a “wicked management problem.” Reducing the nutrients like phosphorus makes the water cleaner and reduces harmful algal blooms and low-oxygen areas called “dead zones.”

That’s good for some fish species, like lake whitefish or walleye. Lake whitefish live on the bottom of the lake and their food supply is affected by low-oxygen dead zones, Ludsin said.
