Sustainable single-cell protein as fishmeal replacement

Researchers at Nanyang Technological University, Singapore, and Temasek Polytechnic have developed a sustainable alternative to fishmeal for farmed Asian seabass by using "single cell protein" derived from microbes in soybean processing wastewater. Published in Scientific Reports, the study demonstrates that replacing half of the fishmeal protein in seabass diets with this protein does not compromise growth, highlighting a significant advancement in sustainable aquaculture. The innovation reduces the reliance on fishmeal, helps combat overfishing, and aligns with efforts towards a circular economy by utilising waste to support food security. (Phys.org)
