Aquafarming, also known as aquaculture, is the practice of cultivating aquatic organisms such as fish, shellfish, and seaweed in controlled environments. This industry has been growing rapidly in recent years, as demand for seafood continues to increase and wild fish populations decline. However, aquafarming has also faced criticism for its environmental impact, including the release of greenhouse gases such as carbon dioxide (CO2) into the atmosphere.
Now, a new initiative is seeking to address this issue by funding projects that enable large-scale carbon removal through aquafarming. The initiative, called the Aquaculture Innovation Challenge (AIC), is a collaboration between the World Wildlife Fund (WWF), Conservation X Labs, and the University of California Santa Barbara’s Bren School of Environmental Science & Management.
The AIC will provide funding and support to entrepreneurs and innovators who are developing new technologies and practices that can reduce carbon emissions from aquafarming, while also improving the sustainability and profitability of the industry. The goal is to identify and scale up solutions that can remove at least one million metric tons of CO2 per year by 2030.
One promising approach is the use of seaweed as a carbon sink. Seaweed absorbs CO2 from the water as it grows, and can be harvested and processed into a variety of products such as food, fertilizer, and biofuel. Seaweed farming has already been shown to have a net negative carbon footprint, meaning it removes more CO2 from the atmosphere than it emits.
Another potential solution is the use of recirculating aquaculture systems (RAS), which recycle water and nutrients to minimize waste and reduce the need for chemical inputs. RAS can also capture and reuse CO2 emissions from fish respiration, which can be used to fertilize plants or algae grown alongside the fish.
Other innovations being developed include new feed formulations that reduce the carbon footprint of aquaculture, and the use of artificial intelligence and machine learning to optimize production and minimize waste.
The AIC has already awarded $100,000 in seed funding to six projects, including a seaweed farm in Indonesia, a RAS system in Mexico, and a feed company in the United States. These projects will receive mentorship and support from the AIC team, as well as access to a network of investors and industry experts.
The potential benefits of large-scale carbon removal through aquafarming are significant. Not only could it help mitigate the impacts of climate change, but it could also create new economic opportunities for coastal communities and improve the sustainability of the seafood industry. With the support of initiatives like the AIC, aquafarming could become a key player in the fight against climate change.
