Louisiana Rep. Patrick Williams (D-Shreveport) is trying to draw attention to the invasive aquatic weed giant salvinia that continues to clog many waterways in the state. He invited the inventor of the "WaterMower" to address the House Committee on Natural Resources and Environment during a May 8 hearing. Williams said his constituents want to see results that go beyond chemical sprays and weed eating weevils raised in university research labs.
Fisheries biologist manager Evan Thames says the invasive aquatic weed giant salvinia is not growing out of control. The Louisiana Department of Wildlife and Fisheries is adhering to a four-day per week chemical spray schedule to keep the plant at bay.
