What should people do if they see Caulerpa taxifolia in the river or the Gulf?
Everyone boating, fishing or taking part in any water sport should be vigilant and report a sighting to FISHWATCH on 1800 065 522 wherever they find it. To make sure you know what it looks like, a pamphlet entitled Identifying Caulerpas in South Australian Waters is available from PIRSA and is posted on this website. People who see the weed should note the location, date of siting, water depth (if possible), type of siting (while diving, on an anchor chain, from the shore), whether it was isolated or a big patch, and your contact details.
