Commercial production of 'white worms' for fish feed

Aquarium fish keepers know that 'white worms' – tiny worms in the genus Enchytraeus – make excellent fish food, but they are not yet available in the quantities needed for commercial aquaculture. The team behind this project point out that enchytraeid worms occur naturally in decaying seaweed, where they can reach enormous densities, and contain high levels of protein and lipids, including valuable long-chain omega-3 fatty acids. They plan to use seaweed for the industrial production of enchytraeid worms to provide a feed ingredient that is better than fishmeal or insects in terms of both quality and sustainability.
