Free-range fish farming

Mexico (Guaymas)

This free floating, untethered deep ocean fish habitat looks like a giant underwater hamster ball: Aquapods are giant, free range fish farms that float deep under water and provide a solution to the fact that the world’s seas could soon run out of fish.

On average, people eat four times as much fish now than they did in 1950 – and in 2015 global fish consumption hit a record high of 17kg (37 pounds) per person per year. This increasing demand for fish on our plate has lead to overfishing with no time for fish populations to recover.

We have turned to fish farming – or aquaculture – as a strategy to meet the growing demand for seafood.  Aquaculture is exactly what it sounds like – farming fish, crustaceans, molluscs, aquatic plants, algae and other organisms – under controlled conditions. Combined with agriculture, it improves livelihoods, as well as alleviating food shortages for small-scale farmers. However, as current methods of fish farming often involve crowded, tethered pens with poor water circulation, disease is spread and huge amounts of environmental stress are put on of surrounding waterways.

Steve Page at Ocean Farm Technologies, based in Mexico’s Sea of Cortez, has come up with a solution – a unique containment for marine aquaculture, tethered offshore. The Aquapod is inspired by naturally occurring schools of fish and the ‘geodesic dome’, North American architect Buckminster Fuller’s spherical shell structures.

Its unique ability to change location with the ocean’s current creates less stress on surrounding environments and reduces overcrowding as the fish are free to move in the same way they would in the wild. The fact they are located at least a mile out at sea in deep water means the fish are as wild as they could possibly be, whilst still being farmed – a true free range fish.

Want to know more about aquaculture? In the sprawling high plains of the Free State province of South Africa, Conchita Milburn is playing a key part in freshwater aquaculture projects. As head of the Gariep Dam Hatchery, she shares knowledge on sustainable practices and supports emerging farmers. We talked to the aquaculture mentor about sustainable fish farming, being a woman in a fishy world – and why catfish are hardcore  ► Aquawoman: Fishy FutureHero

    If one is interested in this project and make it his own or expand it in his region (South East Asia), how can we transpire to make it a reality?

  2. Atul Kinagi

    I would like to know what kind of investment is needed for Aquapod fish farming here in India.

    I am a resident of the northwest Washington State, the Atlantic salmon fish farms are not eco-friendly. I would love to learn more about the possible placement of geodesic dome farms off the west coast to produce fish and end the danger to our wild fish populations in the Strait of Juan de Fuca. I am not against farming fish only the net farms that produce pathogens and introduce concentrated pollutants to our near shore waters.

    heyy, I want to start my business in aquaculture field in Dubai city. I need to know how much it cost to make a geodesic dome

  5. Co-Manci

    Hi. How do we get in contact with you?

  6. anthony gugino

    Where can you buy this fish in the United States?

  7. Imam Jaya Rahmat

    Dear Sirs, I would like to know what kind of investment is needed for Aquapod fish farming here in Indonesia.

  8. Dlayne Blair

    I would really like, additional information about this method, if possible any advice or mentor ship would be appreciated.

  9. Amos Melegepa

    in one dome, how many fishes can you harvest (on average)?

  10. Sam Halpin

    Just curious as to your thoughts about the risk of poaching once the Aquapods are no longer in fixed locations.

  11. Engin Onalan

    Dear Sir,

    I planning to make sea farming. And i can invest for this job. But when i search in the internet, your geodesic farms are incredible. If i want 1000m3 farm, what is the cost? If you directed me, we can coopearation for buying this geodesic farms.

    Best regards.

    We are interested to benefit from Aquapod technology in Nigeria
