A study at Auburn University has evaluated inclusion rates for bacterial, dried fermented biomass for Florida pompano feed.
Previous research has shown that, for pompano diets, fishmeal can be partially replaced with many plant and animal proteins without affecting fish growth rates, and that amino acid supplementation improves growth performance. Various co-products from diverse manufacturing processes are being increasingly used as alternative ingredients in aquaculture feeds, including corn and wheat coproducts from the manufacture of biofuels and ethanol production, such as distiller’s dried grains with solubles (DDGS), fermented bacterial biomass, or ethanol yeast. Microbial single cell protein (SCP) sources include algae, fungi, yeasts and bacteria. Because these coproducts are secondary products of larger commodities, they provide high nutritional value at lower cost.
In this study, researchers evaluated the inclusion of a dried, fermented bacterial (DFB) biomass (a co-product of amino acid production) as a fishmeal replacement in practical diets for Florida pompano.
