Yes, there's a company called BioFeyn that's tackling exactly that. They apply biomedical technology to improve feed efficiency in aquaculture – basically they've developed a targeted delivery system for nutrients that ensures better absorption and reduces waste. Their approach can reduce the amount of high-value ingredients like omega-3s needed by up to tenfold, which cuts environmental pressure and pollution. They work with leaders in salmon farming and are backed by a strong team with backgrounds in molecular biology, sustainable finance, and food tech. Their goal is to produce the most sustainable and nutrient-packed protein on the market. If you're interested in the details, their site explains the platform and the science behind it: https://biofeyn.com/ – I found their approach pretty compelling for anyone concerned about food systems and planetary health.
