Commercial aquatic culture needs manufactured ,specially formulated and nutrient feed to keep them health and productive. While all animals needs to eat and all farmed animals need to be fed, aquaculture represents the most efficient method by which to convert feed to edible protein. Research through the NOAA-USDA Alternative Feeds Initiative has accelerated progress toward reducing fishmeal and fish oil use in aquaculture feeds while maintaining the important human health benefits of seafood consumption.The remarkable progress in developing alternatives has reduced reliance on wild fish caught for this purpose.
