Microcystis is a type of freshwater bacteria commonly found in specific types of harmful algae blooms, and is known to release toxins into the water which can be dangerous to aquatic ecosystems, animals and humans. This bacteria tends to float near the surface of nutrient-rich and low-salinity waters.
The Cape Fear River Partnership, U.S. Fish and Wildlife Services, UNCW, and Cape Fear River Watch have teamed up to provide a risk assessment for Microcystis blooms on five NC rivers, and are currently in progress.
