Fly Frass Forms Fabulous Fish Food

Frass, a byproduct of the larval meal industry, contains larvae waste, exoskeleton sheds, and residual feed ingredients.

Food producers are working hard to ramp up production to meet the needs of a world population expected to reach 9.7 billion by 2050. American aquaculture – specifically catfish farming – will help meet these needs with innovations developed by a microbiologist with the ARS Aquatic Animal Health Research Laboratory in Auburn, AL. A new fish food made from fly frass is helping fish farmers raise larger, healthier catfish.

Frass, the leftover waste of black soldier fly larvae, contains about 18-21 percent protein, about 5-7 protein lipid, and an amino acid profile that is better than traditional fish food made of corn meal and wheat short. Fly frass, which is available commercially, is a byproduct of farming insects for processing into protein meal and oil for biofuel.
