Where has invasive seaweed been found in the San Diego area?
SAN DIEGO (FOX 5/KUSI) — Small patches of invasive seaweed have been found in coastal San Diego, causing concern regarding its spread.
It has been found in the Coronado Cays in the San Diego Bay. The seaweed, known as Caulerpa prolifera, was first discovered last September.
FOX 5/KUSI previously reported that someone’s decision to pour aquarium water into the bay is what led to the spread. Nearly $100,000 has since been spent in efforts to reverse the damage.

Caulerpa seaweed is illegal to possess, sell or transport under California law.
Divers have been working to eliminate the invasive algae by covering them with a sealed barrier, blocking it from light, oxygen and tidal circulation, according to the Port.
An emergency declaration has also been renewed to mitigate the issue.
Caulerpa prolifera is native to Florida and other subtropical locations but it can take over nonnative natural habitats, which then disrupts the ecosystem.
This went unchecked back in the 80s, causing millions of dollars in damage to tourism and the fishing industry.
