Does anything eat Hydrilla?

What does Hydrilla do to the aquatic ecosystem?
It will shade out native aquatic plants until they are eliminated. This forms a monoculture, which will reduce biodiversity and alter the ecosystem. Hydrilla not only poses a threat to other plants but to animals as well.
What kind of fish are affected by Hydrilla?
Dense growths of Hydrilla stunt bass, panfish and other sportfish. Large masses of Hydrilla reduce flow in drainage canals resulting in flooding, erosion and restricted navigation. Swimming, recreation and property values can be negatively impacted.
How much Hydrilla can a grass carp eat?
