Aquaculture

As a long-time champion and catalyst of our water-dependent economy, the Port is taking an active leadership role in expanding the domestic aquaculture industry and facilitating early development of regional marine aquaculture projects like the practice of growing shellfish and seaweed.

Aquaculture in and around San Diego Bay

The Port of San Diego is actively advancing aquaculture through the practice of growing seaweed and/or shellfish in aquatic environments in and around San Diego Bay. San Diego Bay and surrounding areas have several characteristics supportive of shellfish and seaweed aquaculture, including a temperate climate, proximity to markets, and existing shore-side infrastructure.

Shellfish and seaweed aquaculture can provide sustainable commercial opportunities in multiple areas, including food production, biofuel, bioplastics, and other alternative materials. When properly planned, managed, and operated, shellfish and seaweed aquaculture can co-exist with other maritime functions and provide many benefits such as improving water quality, habitat enhancement, carbon sequestration, and ecosystem restoration.

San Diego Bay and its surrounding environment has the potential to support a growing and viable shellfish and seaweed aquaculture businesses that also aligns with the Port’s mission, advances science, and grows a new industry sector with strong potential for job creation and related economic and environmental benefits for the region.

Shellfish and Seaweed Aquaculture Program (SSAP)

The Port is proposing to develop a Shellfish and Seaweed Aquaculture Program (SSAP) and is looking for the public’s input on plans to establish three in-water and three landside aquaculture operation locations. The SSAP provides a framework for the Port to guide, consider and approve future shellfish and seaweed aquaculture activities through the program.

 

 

SSAP Discussion Draft

As a port of communities, we are looking to community members and stakeholders to provide feedback on the Port’s proposed SSAP. On August 20, 2024, the Port released the SSAP Discussion Draft for a 60-day review period seeking comments, data, and discussions on potential opportunities or gaps in the preliminary SSAP.

The comment period closed on October 25, 2024. Port staff will review the comments and prepare an updated draft of the SSAP. The process to develop the SSAP is designed to be iterative and responsive to feedback, and this process will likely continue to evolve as the SSAP evolves.

Aquaculture Pilot Projects and the
Blue Economy Incubator

The Port is taking an active leadership role in expanding the domestic aquaculture industry and facilitating early development of regional marine aquaculture projects by investing in two aquaculture businesses through its Blue Economy Incubator. Below are two examples.

Sunken Seaweed


Sunken Seaweed is a seaweed farm located at the northwestern end of Grape Street Pier and is made up of a rectangular grid system in which various seaweeds species are being grown in the San Diego Bay. The seaweed grown can be used for consumption, fuel, feed, and even packaging. In 2023, Sunken Seaweed was featured on the TODAY Show’s Earth Week coverage and on NBC’s show Lx.

San Diego Bay Aquaculture


San Diego Bay Aquaculture grows Pacific oysters from seeds the size of pepper flakes to juvenile stage, or about the size of a quarter. Once at juvenile stage, the oysters will be exported to farms for further grow out. In 2023, TODAY Show co-host Al Roker toured San Diego Bay Aquaculture operations and featured them on his Earth Week coverage.
