FWC’s Position Statement Hydrilla Management ………….FWC prefers to manage for native aquatic plants, but recognizes that in waterbodies where native submersed aquatic plants are absent or limited, hydrilla at low to moderate densities can be beneficial to fish and
- wildlife. FWC will manage hydrilla on a
waterbody by waterbody basis using a risk-based approach to determine the level of management……………
