UC Santa Cruz and Global Algae Innovations have secured a $2 million grant to cultivate Spirulina microalgae using CO2 from power plant emissions, aiming to provide a sustainable fish feed alternative. If successful, this could revolutionize aquaculture feed, reducing reliance on traditional sources.

In an innovative move to tackle carbon emissions and sustainability challenges in aquaculture, UC Santa Cruz, in collaboration with Global Algae Innovations, has secured a $2 million grant from the US Department of Energy. The project’s mission is to cultivate Spirulina microalgae using CO2 captured from power plants. Recognized for its rich nutritional content, Spirulina offers a promising sustainable fish feed alternative.

The initiative is twofold: reducing carbon emissions and establishing sustainable fish feed sources. Global Algae Innovations will harness CO2 from power plant exhausts, emphasizing energy and cost efficiency. Subsequent tests, led by Assistant Professor Pallab Sarker, will evaluate the Spirulina’s nutritional profile and safety. The final phase involves feeding the CO2-grown Spirulina to rainbow trout to assess its digestibility and appeal.

CEO of Global Algae Innovations, Dave Hazlebeck, emphasized the project’s focus on tailoring algae cultivation for fish feed. If successful, Spirulina might revolutionize the fish feed industry, reducing dependence on wild-caught fish and other traditional sources.
