We have a winner– ten of them! Australian Foreign Minister Julie Bishop today announced the winners of the Blue Economy Challenge at the World Wildlife Fund headquarters in Washington, D.C. The winning innovations range from low-cost micro-scale farming to improved seaweed farming technology for women to vaccine-carrying fish feed. We can’t wait to see how these innovations revolutionise the aquaculture industry.

Thanks to everyone who participated in the challenge! We encourage those of you who were not selected as finalists or winners to stay engaged in the aquaculture innovation community and apply for other innovationXchange opportunities as they arise.

Here are the winning innovations in alphabetical order:

1. AgriProtein Technologies: Industrial-scale insect meal protein replacement of fishmeal in fish feed

Team: David Drew, Jason Drew, Cobus Kotze, Johnny Kahlbetzer
Wild-caught fish are a primary source of nutrients in current aquaculture feeds, and natural fishery populations are consequently being depleted to feed farmed fish. AgriProtein Technologies uses human food waste to grow insect-based feed replacement for the aquaculture industry. The feed is competitively priced and has significant potential to scale across the Indian Ocean Region and globally, all the while contributing to a reduction of pressure on wild fish stocks.

2. Bridging International Communities: Oasis Aquaponic Food Production System

2 bridging international communities
Team: Michelle Leach, Jacquelyn Hernandez Ortiz
In many parts of the Indian Ocean Region, access to fresh and nutritious foods can be limited. The Oasis Aquaponic System is a low-cost, low-resource-use, and solar-powered household ‘farm-in-a-box’ capable of producing 90 kilograms of tilapia and 270 kilograms of vegetables annually – providing reliable and healthy food for households and small communities. This system has the potential to dramatically impact household level nutrition in remote and island communities as well as urban settings.

3. Climate Foundation: Open water Marine Permaculture Arrays

In many parts of the world, changing climate has prevented natural ocean upwelling—a process that brings nutrient-rich waters to the sea surface resulting in aquatic plant and animal productivity. Without this naturally occurring process, kelp forests and seaweed farms are suffering and dying. The Climate Foundation has engineered a cutting edge system to reverse this process manually: pumps placed at the ocean floor, powered by wave energy, manually restore upwelling in areas where it has stopped. The nutrient-rich waters are directed towards the seaweed farmed in permaculture arrays. These arrays may eventually have the potential to operate automatically, roaming the deep seas and returning to shore at harvest time.

4. EnerGaia Co. Ltd: Sustainable production of Spirulina

Team: Saumil Shah, Derek Blitz, Ingo Puhl, Siriporn Nuchyai, Annop Jittijarunglarp, Minh Buu, Na Manasak, Amonporn Peekarn
EnerGaia has devised a way to farm Spirulina, a nutritious algae super-food, that not only tastes good but can be grown anywhere. The company grows Spirulina on urban rooftops, but their production unit can be outfitted to grow anywhere worldwide. The algae is harvested, dried, and ground into a powder, which can be used as a vitamin supplement or added directly to recipes. EnerGaia will increase their production in the Indian Ocean Region by outsourcing to contract farmers (particularly women) – providing a reliable income with a guaranteed market for the algae.

5. Indian Ocean Trepang: Sea cucumber farming for local communities

While some aquaculture facilities are high-tech, not all aquaculture farms need high inputs of energy and resources to be successful. Indian Ocean Trepang grows, processes, and sells sea cucumbers to consumers worldwide. Their unique model involves partnering with local fishing villages so that the sea cucumbers can mature at sea and not in expensive facilities. It’s a low-tech solution that connects communities to a growing and lucrative market for sea cucumbers. Scaling this production method across the Indian Ocean Region could provide significant alternative income and prosperity to local communities and reduce pressure on wild fisheries.

6. Institute of Marine Sciences — SEA PoWer: Improved seaweed farming technology for women

Team: Dr. Flower Msuya, Dr. Cecile Brugere, Dr. Ritha Maly, Dr. Betty Nyonje, Dr. Narriman Jiddawi
Traditional peg-and-rope seaweed farming is currently used by many women farmers in Tanzania. These women are working in often hazardous conditions, and climate change has reduced the economic productivity of this shore-based aquaculture industry. Dr. Flower Msuya and her team at the Institute of Marine Sciences are adapting a new “tubular net” technology to meet the needs of these women farmers – these nets will be easier to operate and should provide increased and more reliable seaweed production, resulting in increased income and improved standing in the local community.

7. MicroSynbiotiX, Ltd.: Algal oral vaccines for disease management

9 MicroSynBiotiX
Team: Simon Porphy, Antonio Lamb, Sebastian Cocioba, Dr. Kwang Chul-Kwon
Aquaculture farmers are at a high risk of losing fish, and therefore revenue, due to bacterial and viral diseases that spread easily and quickly in tanks. MicroSynbiotiX is developing a potentially revolutionary microalgal feed that will be a vehicle for a range of vaccines. Benefits of this innovation will include a reduction in antibiotic use, reduced fish loss from disease outbreaks and increased productivity for aquaculture farmers.

8. Odyssey Sensors: A low-cost solar-powered salinity sensor

12 Odyssey sensors
Team: Wayne Turner, Stephen Honan, Mike Cruse, Hiranmoy Battacharjee, Gary McDarby, Christopher Hunter, Michael Thornton, Kevin Baum, Syeed Huq, Holden Bonwit, Selim Reza Hasan
Salinity testing in aquaculture tanks and ponds is of critical importance to the health and productivity of shrimp and finfish. Current sensors on the market are often expensive, highly technical, or dependent upon electricity – leaving some farmers to rely on unreliable and inaccurate taste-testing. Odyssey Sensors has designed and field-tested a salinity sensor that is low-cost, easy to use, and solar powered, and has the potential to double aquaculture crop yields. Working with partners in the field to distribute through local markets, this low-cost sensor could be a game-changer for salinity testing.

9. The Recycler Ltd.: Larvae from biowaste for aquaculture feed

Team: Matthew Haden, Christian Zurbrügg, Stefan Diener, Adeline Mertenat, Imanol Zabaleta, Moritz Gold, Kigen Compton, Laura Gasco, Marco Meneguz, Ivo Zoccarato, Philipo Stephen, Jonathen Arul, Abdallah Masoud Mtutumu, Prisca Wallace Maugu
Existing aquaculture feeds rely heavily on wild-caught fish, which depletes natural fish populations. The Recycler has a successful track record of raising black soldier fly larvae from food and other biowaste to produce nutritious feed for poultry in Tanzania. Their first forays into refining their insect larvae meal for fish feed look promising. The Recycler is reducing the amount of biowaste ending up in landfills and producing much needed protein inputs for aquaculture at the same time.

10. WorldFish and CSIRO: Novel sustainable aquafeeds


Team: Nicholas Bourne, Sue Cheers, Kazi Ahmed Kabir, Karolina Kwasek, Claire Loy, Mohammad Rashid, Mmochi Aviti, Nigel Preston, Adrian Rara, Cedric Simon, Sharon Suri, Ban Swee Tan, Guy Watson

Annually, one third of wild caught fish (around 30m tonnes globally) are used to make feed for farmed fish. This is unsustainable. Aquaculture is necessary to feed our growing demand for fish and is a particularly important source of nutrition in the developing world. CSIRO created an aquafeed from agricultural waste that uses no wild caught fish and enables farmers to produce fish with zero loss of nutritional quality. WorldFish and CSIRO are partnering to take the novel technology to farmers, in particular smallholders, to enhance their productivity and the performance of local feed ingredients.

  • Dear All,

    Thank you for the update on the winners and more specifically on the innovation. We would like to follow keenly on the oasisaquaponic food production system and how it works and production level Vs input level. Kenya Women Holding through its aquaculture program is keen on developing low cost interventions for women who particularly have no land ownership and have limited space where they set up an aquaponic food production system. We did apply but were not successful and would love to improve for future applications. Thank you for this update and hope to keenly follow up on the impact of the 10 innovations.
