Aquaculture & Blue Technology Program
The Port established the Aquaculture and Blue Technology Program recognizing the growth opportunities of the Blue Economy sector and its strategic position within the world’s leading blue technology clusters.
Aquaculture is the practice of growing plants and/or animals in aquatic environments. This can occur in fresh or salt water and it can be done for food production or for other purposes such as alternative fuel, packaging, bioremediation, and fertilizers.
The Port is taking an active leadership role in the expanding domestic aquaculture industry and facilitating early development of regional marine aquaculture projects.

Blue Economy Incubator (BEI)
The Port’s Blue Economy Incubator (BEI) is building a portfolio of businesses and partnerships that deliver multiple social, environmental, and economic co-benefits to the Port and the region by removing barriers to entrepreneurs and providing funding, key assets, support services including entitlement and permitting assistance, and pilot project facilitation.
Ideas to work sustainably within the marine environment can come from anywhere. The best ideas will transition into concepts, design plans, and then prototypes. After the testing and validation is completed within a lab setting, it’s time to deploy the technology in a real-world setting. That’s when the Port’s BEI can play a role and help emerging businesses deploy their products and services in and around San Diego Bay.

Blue Economy Pilot Projects
Sustainable Seaweed AquacultureSustainable Seaweed AquacultureDownload Sunken Seaweed Scorecard
Sunken Seaweed, an aquaculture start-up company led by two marine ecologists joined the Port’s BEI to demonstrate the feasibility of seaweed aquaculture in San Diego Bay. Sunken Seaweed established a seaweed hatchery at San Diego State University’s Coastal and Marine Institute Laboratory and installed their submerged pilot farm using assets, such as docks and piers, managed by the Port. The company is successfully cultivating, outplanting, growing, monitoring, and harvesting several species of seaweed native to Southern California. Beyond commercialization, results from the pilot project are helping assess seaweed aquaculture’s multiple co-benefits, from carbon sequestration and bioremediation to improving water quality and ecosystem productivity. In 2022, the Port reinvested in an expansion of Sunken Seaweed's pilot which enables the company to build and continue its research in the burgeoning industry in and around San Diego Bay, while expanding operations to Humbolt Bay where they will benefit from shoreside facilities to help them reach market scale. Sunken Seaweed was recently showcased during a 2023 NBC “Climate Today” series with host and NOAA emissary, Al Roker.
Bio-enhancing Shoreline ArmoringBio-enhancing Shoreline ArmoringDownload ECOncrete Scorecard
ECOncrete joined the Port’s BEI to demonstrate a new design of its tidepool shoreline armoring technology called Coastalock. This technology serves as a replacement for traditional riprap and provides ecological armoring and shoreline stabilization, while also creating well-defined local ecosystems that mimic natural tide pools. The pilot project has been monitored since installation and data demonstrates an increase in biodiversity, species richness, and abundance on ECOncrete’s Coastalock units compared to the traditional riprap. Through the Port’s pilot, Coastalock units have achieved technological validation and units have since been deployed in new projects around the world. Additionally, the Coastalock unit won the 2022 Design Educates Award and the 2022 ASCE Award for Outstanding Airports and Ports Project.
Stormwater Monitoring DeviceStormwater Monitoring DeviceDownload FREDsense Technologies Scorecard
The Port approved FREDsense Technologies for a pilot project to develop a portable five-in-one field-testing sensor device to provide real-time metals analysis for stormwater monitoring. FREDsense automatically tests levels of aluminum, copper, lead, zinc, and nickel – all of which are known to enter San Diego Bay through stormwater. The system provides real-time data in the field, which is significantly faster than the several weeks necessary to receive traditional laboratory results, allowing for quicker adjustments to Best Management Practices.
Sediment Remediation in Marine EnvironmentsSediment Remediation in Marine EnvironmentsDownload ecoSPEARS Scorecard
The Port approved ecoSPEARS for a pilot project to demonstrate its innovative in-situ technology to extract and remediate contaminants from marine sediment. ecoSPEARS is the exclusive licensee of the NASA-patented SPEARS technology, which was invented by a team of NASA environmental scientists as a green remediation solution. The pilot focused on the deployment of the ecoSPEARS in three different locations around the bay where the SPEARS acted like sponges, passively absorbing contaminants. The pilot project is near completion and helped ecoSPEARS achieve several milestones. Data from the pilot is expected to be published soon and ecoSPEARS is now engaging other markets in the Pacific Islands, leading to scaled-up deployments.
Shellfish NurseryShellfish NurseryDownload San Diego Bay Aquaculture Scorecard
San Diego Bay Aquaculture is testing if a shellfish nursery, called a FLUPSY, or Floating Upweller System, can be effective in helping address a coast-wide shellfish seed shortage. The FLUPSY is a floating barge that circulates water through compartments or bins holding shellfish, in this case oysters, as they grow from about the size of a red pepper flake to about the size of a quarter when they are ready to go to the farm. The operation of the FLUPSY, combined with the region’s mild weather and nutrient-rich water, offers a competitive advantage over northern shellfish nursery sites because seed to harvest time is reduced up to one year compared to northern locations. After being in the FLUPSY, shellfish will be transported to a farm where it will grow to market size. Approvals to conduct this pilot have been slow to obtain, but San Diego Bay Aquaculture is using the FLUPSY to conduct much needed research for oysters, abalone, and seaweeds, and production is expected to begin this year (2023). The FLUPSY is being more widely recognized after being showcased during a 2023 NBC “Climate Today” series with host and NOAA emissary, Al Roker.
