Solutions to aquatic vegetation problems are often extremely complicated and dynamic, involving factors such as vegetation type, water exchange rate, growing season, secondary infestations, dissolved oxygen crashes, water visibility, plankton blooms, etc.  Therefore, we recommend you consult with a qualified field biologist for a management plan that considers options like biological control, mechanical control, chemical control, and environmental control.  At Overton Fisheries, Inc, we are certified for commerical application of aquatic herbicides by the Texas Department of Agriculture, licensed for culture and sale of exotics like grass carp and tilapia, educated at Texas A&M University, and experienced with hundreds of vegetation problems around the state.  Give us a call at 903-322-2626 or 1-866-347-4327.  We operate two sizes of airboats and can maneuver into even the most difficult of infestations.
