The NSW Department of Primary Industries is working closely with a range of stakeholders to control a noxious weed in Wallagoot Lake, on the NSW Far South Coast. NSW DPI Manager Aquatic Biosecurity & Risk Management, Jane Frances explained that caulerpa taxifolia (Caulerpa) is listed as a noxious species in NSW. She told that it is a threat to NSW native marine environment, as it spreads quickly and can potentially impact native seagrasses and possibly reduce fish stocks.
It is informed that till recent Caulerpa has been found in 14 estuaries and lakes in NSW. It was first discovered in Wallagoot Lake on the Far South Coast in 2007. Frances told that previous control work using salt application has resulted in some existing areas being reduced significantly in size.
Frances expressed that it is good for the people to know the presence of Caulerpa in Wallagoot Lake, and that if fragments are found on any fishing or boating gear, such as fishing rods or anchors, that they are removed and put in the bin. Caulerpa can easily become entangled in fishing and boating gear. It is said that NSW DPI will return to Wallagoot Lake later in summer of 2009/10 to conduct further monitoring, and discuss potential future options for the management of the weed.
