A recent discovery of an invasive alga in the China Cove area of Newport Bay is drawing concern from officials due to the rapid growth and threat to the environment.
The alga, which is native to Florida and other subtropical and tropical locales, is scientifically known as Caulerpa prolifera. This is the first positive identification of Caulerpa prolifera on the West Coast.
Caulerpa prolifera is a popular saltwater aquarium plant that has a high tolerance to severe nutrient limitations and salinity and temperature fluctuations. It is also known to produce toxic secondary metabolites that may be toxic to marine invertebrates and fish.
How it arrived is unclear. The plant was first discovered by a local diver who then reported the oddity to authorities.
The Santa Ana Water Board is engaging with other federal, state, and local agencies to quickly identify the extent of the algae’s infestation and develop a plan of action.
Although there is significant concern this species could be harmful to native species, the Caulerpa isn’t dangerous to humans. Authorities are asking the public to avoid any contact such as by diving or boating in the area as it could cause the plants to break apart and spread further.
If you believe you have seen this invasive algae, please visit the CDFW’s Reporting a Caulerpa Sighting webpage and submit a report. Please do not collect a specimen, as this may lead to further spread.
