Affordable and sustainable feed ingredients for fish farmers are in the works as researchers continue to develop fish diet formulations using discarded agricultural wastes and byproducts. Dr. Frolan Aya, a scientist at the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC/AQD), and his colleagues examined agricultural wastes and byproducts for potential inclusion in diets formulated for omnivorous fish such as Nile tilapia (Oreochromis niloticus) in their study, “Potential use of agricultural wastes in aquafeed production.” Fruit peels, pulps or brans, seeds, bagasse (sugarcane residue), molasses, and okara (soybean curd residue) comprise 40 to 60 percent of wastes generated from major crop industries such as coconut, banana, pineapple, mango, citrus, and sugarcane.
