Invasive species from all over the world have been introduced to Irish waters and impact our freshwater environment. Invasive species can outcompete native species, spread disease and can block waterways and riverbanks, interfere with fishing, damage boats increasing maintenance costs and make navigating in boats, canoes and kayaks difficult. As a water user, you may unknowingly be helping to spread invasive species from one water body to another in equipment, shoes and clothing. Help stop this happening by following three simple steps when you leave the water: CHECK your gear, clothing and footwear after leaving the water for mud, aquatic animals, or plant material. CLEAN everything thoroughly as soon as you can. Pay particular attention to nets, waders, and areas that are damp and hard to inspect. If possible, use hot water (at least 45°C) or a high-pressure spray. DRY all equipment and clothing until dry for at least 48 hours before using it again as some species can live for many days or weeks in moist conditions. In this video, Professor Joe Caffrey, Invas Biosecurity, describes two aquatic invasive species that have serious impacts on the freshwater environment - Curly Waterweed (Lagarosiphon major) and Zebra Mussel (Dreissena polymorpha). We also hear from Martin McEnroe, President of the Angling Council of Ireland, on the important role that boat users and anglers play in stopping the spread of invasive species by following the Check Clean Dry protocol.
