Can Aquaculture Feed the World Sustainably?

Christine Gould

The UN has declared 2022 the International Year of Aquaculture. But, what is the future of fish farming? Is it in coastal areas? Perhaps it’s miles from the sea, in freshwater ponds owned by smallholder artisans. Maybe it’s nowhere near water at all, but in a lab…or in space.

Here are some exciting startups from all over the world focused on making the fish we eat more sustainable: 

Aquaculture currently relies on fishmeal made from wild fish. But, new alternatives are emerging such as Tanzania’s NovFeed, which uses bacteria and blackfly larvae to recycle organic waste into high-protein feedstock. NovoNutrients in the USA are converting waste CO2 into nutritious feed using synthetic bacteria and renewable energy.

To keep fish healthy, many aquaculture farmers must renew the water in their fish ponds every week. When they do this, excess nitrogen from fish manure ends up in waterways. That’s why Mexico-based MicroTERRA is tapping into the power of the aquatic plant lemna. Lemna cleans the water in ponds, and then it can be harvested and processed to make a high protein, high value, functional food ingredient. Banoo, an Indonesian startup, has developed an affordable and solar-powered microbubble generator that improves water quality in inland fish ponds by increasing dissolved oxygen levels.
