Several methods for controlling Caulerpa have been trialled overseas and within Australia, ranging from physical removal (by hand or mechanically) to smothering and treatment with various chemicals. From 2001, I&I NSW conducted experimental trials of some of the most promising of these methods (particularly smothering with various materials, suction dredging and salt treatment). Primary Industries and Resources South Australia have also trialled various methods, including large-scale treatment with fresh water All of these methods have advantages and disadvantages relating to their specificity, risk of increased fragmentation, ecological impacts, ease of implementation, and the need for repeat treatments and cost. Most of these factors depend to some extent on the size and nature of the affected area. No single method has yet been demonstrated as achieving permanent eradication of large, established areas of Caulerpa. I&I NSW has found salt treatment to be the most useful control option to date in the short‑term control of Caulerpa. Covering beds with around 3 to 6 centimetres of coarse salt (equivalent to 50 kg per m2) rapidly kills almost all of the treated Caulerpa. Although other species such as seagrasses and benthic invertebrates are also affected in the short term, they appear to recover relatively rapidly, apart from Posidonia seagrass, which is susceptible to salting.
