Globally, the aquaculture industry is one of the fastest-growing sectors in food production. To modulate the health and growth conditions of aquaculture species, probiotic feed supplements, additives, and immunostimulants of microbial origin have been used. Yeasts are becoming increasingly significant in meeting the nutritional requirements of aquaculture species, with Saccharomyces cerevisiae being the most extensively studied. Several other potential non-conventional Ascomycetous yeasts, such as Debaryomyces hansenii, Yarrowia lipolytica, Candida spp., Wickerhamomyces spp., Kluyveromyces spp., Blastobotrys adeninivorans, and Metschnikowia spp., are emerging as lucrative alternatives. Products such as β-glucans, mannan oligosaccharides, pigments, and nucleotides derived from them are also gaining popularity for enhancing the overall health and performance of aquaculture species. These lesser-explored yeast genera are utilized as probiotics, feed additives, nutritional supplements, or immunostimulants in the aquaculture industry. They help improve growth performance, antioxidant activity, and hematological parameters of aquaculture species. When included in diets, they can enhance immunity, digestion, and disease resistance against various pathogens affecting aquaculture yields. Some also serve as protein sources or enhance pigment production. Strategies such as using low-cost substrates, optimizing process parameters, metabolic engineering, and genetic manipulation of these yeasts are crucial for their sustainable application in aquaculture. This review summarizes the effects of non-conventional Ascomycetous yeasts in improving the overall well-being of various aquaculture species.
