A $200,000 grant will fund diver surveys and eradication efforts for Caulerpa prolifera, a fast-growing alga that chokes native seaweed and eelgrass threatens native marine. The grant was allocated by the Pacific States Marine Fisheries Commission to the Port of San Diego. In April and August of 2025, divers found small patches near the San Diego Bay National Wildlife Refuge. To date, approximately 11,300 square feet of Caulerpa have been identified in San Diego Bay of which more than 300 square feet is within the Port’s jurisdiction. The South San Diego Bay spans about 3,000 acres.
