Abstract

The aquaculture sector is growing exponentially and has certainly gained popularity in the international economics and development agenda across the world. The challenges in aquaculture intensification can be solved by establishing sustainable technologies that could boost the rapid growth rate while minimizing disease outbreaks. Host physiology is influenced by the microbiome; thus, its modulation can improve human and animal health. This can be achieved through the introduction of beneficial microorganisms (probiotics), a supply of substrates to support the growth of commensal microorganisms (functional additives) and fecal transplants. Functional additives include prebiotics, immunostimulants, and short-chain fatty acids (SCFAs). Prebiotics have been reported to improve growth performance, feed utilization, survival, carcass composition, health status, disease resistance, immune functions, microbiota modulation, and reduced oxidative stress in aquaculture. Prebiotics confer benefits in fish through changes in bacterial communities; they act as energy sources for beneficial bacterial species that ferment prebiotics. The by-products of this fermentation (SCFAs, vitamins, and peptides) are responsible for the beneficial effects of prebiotics in fish. In this chapter, we summarize the effect of prebiotics and their application in aquaculture as functional feed ingredients for fish nutrition and provide perspectives on the potential application of prebiotics in aquaculture in Africa.
