Prebiotics based on mannan-oligosaccharides in fish feeding (a review)

Abstract

Purpose. To analyze the array of special literature and summarize the information obtained on the peculiarities of prebiotics based on mannan-oligosaccharides. To review the basic principles and prospects of their application in fish feeding, first of all in the conditions of aquaculture of Ukraine. Findings. An overview of modern scientific publications on the pecularitires of prebiotics based on mannan-oligosaccharides, the prerequisites for their widespread use and prospects for use in aquaculture is presented. The literature data on main directions of the effect of these drugs on non-specific immunity of fish and increase of resistance of fish body are summarized. The expediency of using prebiotics in reservoirs of different types is reviwed, considering the environmental safety of these drugs. The prospects of creating new generations of prebiotics based on mannan-oligosaccharides and their use in different types of fish farms in Ukraine are shown. The obtained results testify to the expediency and efficiency of using the prebiotic “Actigen” in fish farming. Introduction of prebiotics based on mannan-oligosaccharides to feeds of different composition helps to obtain additional growth and increase the economic component in the cultivation of fish to marketable condition. Practical Value. The review can be useful for scientists, postdoc students, gdaduate students, government officials and private entrepreneurs involved in the process of production of aquaculture products, fish feeding and maintaining the environmental safety of water bodies. Keywords: prebiotics, mannan-oligosaccharides, fish feeding, feed conversion, non-specific immunity, resistance, microbiota.
