As duck season approaches, Texas Parks and Wildlife Department officials are asking hunters to inspect and clean their gear before moving between water bodies. Officials said invasive plants such as giant salvinia and zebra mussels are present all year and can spread on boats, trailers, decoys and hunting waders.
Giant salvinia is a floating fern native to Brazil and is among the most widespread threats in East Texas waterways, officials said. The plant can form thick mats that block public access and sunlight and lower oxygen levels in the water. TJ Puller, a fisheries biologist with Texas Parks and Wildlife, said that invasive species spread quickly when introduced to waters where they do not normally live. Puller said cooler winter weather does not stop the problem.
Officials advise hunters and other outdoor users to follow the Clean, Drain, and Dry protocol each time they leave the water. Transporting aquatic invasive species is against Texas state law and can carry fines of up to $500 per violation.
