Successful aquaculture and aquaponics depend on a population of fish that are regularly fed, like any other livestock. Standard commercial fish feeds are pellets containing protein from endangered, depleted populations of ocean fish such as anchovies.

To be sustainable, aquaculture must look to alternative fish feeds such as insects, earthworms, and high-protein plant leaves such as comfrey and alfalfa, feeds that have been tried successfully at New Alchemy.
