That’s the challenge scientists at the Bioeconomy Science Institute Maiangi Taiao are tackling as they work to develop new foods for larval fish. Their research could help reduce reliance on traditional live feeds and support a more resilient aquaculture industry, one of the world’s fastest-growing food production sectors.\n\nIn this episode of Scigest, scientist and host Julie Blommaert joins scientist Hemi Cumming to explore the surprisingly complex world of feeding tiny fish.  They discuss the challenge of creating a microfeed that delivers the right nutrition while also behaving like the live food larval fish naturally respond to. One of the main live feeds currently used in aquaculture is Artemia, brine shrimp many people will know as Sea-Monkeys. But relying on Artemia comes with risks, including supply uncertainty and the potential for disease. Could a specially designed microfeed provide a more reliable alternative? \n\nDive into the science behind creating very small food for very small fish and discover why getting it right could make a big difference for the future of aquaculture. \n\nTo view our full catalogue of podcasts including extra links on some podcasts please go to our Scigest pages: www.plantandfood.com/scigest","title":"Microfeeds - the challenges of producing tiny fish food"},"cardImage":{"sys":{"id":"23aNoib0h8F4xKMkfYc7nl","publishedVersion":4},"url":"https://images.ctfassets.net/y9no91j9bwnp/23aNoib0h8F4xKMkfYc7nl/c1cf1c69d5c402e21665c135a0fa7c1c/podcast-2026-microfeeds-the-challenges.jpg","title":"Microfeeds - the challenges of producing tiny fish food","height":1406,"width":2500,"contentType":"image/jpeg"},"shareImage":{"url":"https://images.ctfassets.net/y9no91j9bwnp/23aNoib0h8F4xKMkfYc7nl/c1cf1c69d5c402e21665c135a0fa7c1c/podcast-2026-microfeeds-the-challenges.jpg"},"publishDate":"2026-09-18T00:00:00.000+12:00","content":null,"contactBlock":{"__typename":"Contentful_BlockGetInTouch","sys":{"id":"3vtnDWOEZfTHV2fURsAIO1","publishedVersion":39},"heading":"Get in touch","subHeading":"Interested?","colourway":{"label":"Purple"},"callToAction":{"__typename":"Contentful_Link","sys":{"id":"6duaiOQrpF2reo5g7x0uRd","publishedVersion":7},"label":"Contact Us","externalUrl":null,"internalPageQueryString":null,"openInNewTab":null,"internalPage":{"__typename":"Contentful_Page","urlSlug":"contact-us"},"variant":"Primary","buttonSize":"large","file":null},"image":{"__typename":"Contentful_ImageWithFocalPoint","sys":{"id":"57Egf2RaZ9AoZ0DHpZMbAz","publishedVersion":3},"focalPoint":{"focalPoint":{"x":1201,"y":388}},"image":{"sys":{"id":"2auskQdAfK9HTQwqy8X1eW","publishedVersion":4},"url":"https://images.ctfassets.net/y9no91j9bwnp/2auskQdAfK9HTQwqy8X1eW/1f04e3f46bb9358358ac9173464795d0/image3.png","title":"Get in Touch","height":792,"width":1440,"contentType":"image/png"}}},"creditsCollection":{"items":[{"title":"Dr","firstName":"Hemi","lastName":"Cumming","urlSlug":"hemi-cumming","bio":"He uri ahau ō Ngāti Koata, Ngāti Toa, me Ngāti Raukawa ki te tonga.\n\nMy role spans across both science research and Māori business development. \n\nI have a PhD in Chemistry from Victoria University of Wellington, and my current research interests are in green chemical processes for seafood products, and the investigation of novel microfeeds for native fish larvae aquaculture. \n\nI am the Māori co-lead for our internally funded ‘Ngā Tai Hōhonu / Open Ocean Aquaculture’ direction, where I support the high level strategic direction of the research programmes and develop our strategies to build meaningful relationships with iwi entities, and create opportunities for Māori to develop in the science research system.","photo":{"sys":{"id":"njnjA8fhPaacvbL669wRc","publishedVersion":6},"url":"https://images.ctfassets.net/y9no91j9bwnp/njnjA8fhPaacvbL669wRc/420f9fb4b8de84e4474f8bffac70bb65/profile-photo-hemi-cumming.jpg","title":"Hemi Cumming","height":2875,"width":2875,"contentType":"image/jpeg"}}]},"marketingTeamCredit":false,"researchAreasCollection":{"items":[{"sys":{"id":"5nFhxPq2lJmzKEYKvzZgZF","publishedVersion":4},"label":"Seafood production"}]},"sectorsCollection":{"items":[{"sys":{"id":"1hIahJwLyxf0LUqxvp55vq","publishedVersion":19},"label":"Seafood"}]}}}},"pageContext":{"id":"2Mj7IEYGwXG8055n5gRFbG","preview":false,"language":"en-au","intl":{"language":"en-au","languages":["en-nz","en-au","pt-br"],"messages":{"usefulLinksHeading":"Useful Links","footerNewsletterSubscribeHeading":"Subscribe to our newsletter","footerNewsletterSubscribeSuccess":"Thanks for subscribing!","formValidation.unexpectedError":"An unexpected error has occurred.
