Circular nutrition in aquaculture focuses on reducing waste and closing nutrient loops by transforming fish byproducts into sustainable aquafeed. Simon Das from the Tropical Aquafeed Innovations Lab at James Cook University presents how this model can cut reliance on wild-caught forage fish while supporting cost-effective, nutritionally balanced diets. The lab’s work includes developing weaning protocols for pellet-ready fingerlings, training farmers in advanced feeding practices and economics, and promoting gender and youth inclusion. Circular nutrition highlights how rethinking resource use can make aquaculture both more efficient and more sustainable.

This pitch was presented as part of AquaInnovate, an immersive networking and coaching event for aquaculture entrepreneurs and startups, held in Bangkok from 12–19 May 2025. For more information visit:
