Application of Agricultural Byproduct/Waste as Functional Feed Additives In Aquafeed

Abstract: 

The issue of agriculture circular economy has received attention around the world in recent years. The main purpose of the agriculture circular economy is to promote economic efficiency and environmental protection through waste recycling. Aquafeed is a key issue in sustainable aquaculture. Recently, the active components from plants or their extracts, such as polysaccharides, alkaloids, flavonoids, pigments, phenolics, terpenoids, steroids, and essential oils, have been paid attention in their effects on health control and as a strategy instead of antibiotics and chemotherapies in aquafeed. Our team has evaluated some agricultural byproduct/waste as the functional feed additives in aquaculture industry. The water hyacinth, banana peel, cacao pod husks, and lemon peels, the four commonly agricultural byproduct/waste in Taiwan, have been documented their potentiality in enhancing immune responses, stress resistance, and disease resistance for fish and shrimp. Our studies also reported that simple processing, such as heating, extraction or fermentation, could improve the efficacy of these products.
