San Diego Bay Faces Crisis from Invasive Caulerpa Algae

Emergency measures intensify as fast-spreading seaweed threatens local ecosystems and economy.

Caulerpa prolifera, first discovered in September 2023, has rapidly spread in San Diego Bay.
The invasive algae endangers eelgrass, vital for fish, birds, and green sea turtles.
Officials believe the infestation originated from a saltwater aquarium release.
Efforts include covering algae patches with barriers to block light and oxygen.
Over $3 million in funding is being secured for eradication and monitoring efforts.
