Get to know the work being carried out by Gokulakrishnan Marisami during his Transnational Access visit to Centro de Ciencias do Mar (CCMAR), supported by EMBRC - European Marine Biological Resource Centre and AQUASERV, and developed in collaboration with Aquaculture Research Group (Aquagroup).
🌊 From beer production waste to fish nutrition: closing the loop in food systems At CCMAR, PhD student Gokulakrishnan Marisami is exploring how to transform industrial by-products into high-value fish feed ingredients, helping reduce pressure on global food systems. One of the key challenges in aquaculture today is the reliance on soy protein concentrate, a widely used ingredient linked to: • high land use and deforestation pressures • competition with human food and feed systems • supply chain vulnerability and price volatility At the same time, the brewing industry generates large volumes of brewer’s spent grain (BSG), a by-product that is often underutilized or discarded after beer production. This research brings these two systems together. Through AQUASERV funded access, Gokulakrishnan joined CCMAR to conduct feeding trials with seabream, testing a protein isolate previously developed from BSG using green and cost-effective extraction and functionalization technologies to transform it into a high-value ingredient for aquafeeds. His work evaluates how far soy protein can be replaced while maintaining growth performance, feed efficiency, and fish health. The goal is simple but powerful: 👉 turn waste streams into feed solutions 👉 reduce dependence on soy 👉 build a circular bioeconomy between brewing and aquaculture This is not just feed innovation, it is system redesign. Supported by AQUASERV, this high-potential circular economy project connects industry, science, and sustainability across borders.
