Yeast is one of the best probiotic components in the aquaculture industry. Usage of yeast controlsthe pathogens in aqua ponds by number of mechanisms. It promotes growth, therefore, it increasingly become an important material in the aqua industry. The world is so concern about aquaculture; and the industry uses fishmeal to prepare aqua feed. The reduction in fish meal lead to looking for an eco-friendly alternate. In such a scenario, BIOGREEN TECHNOLOGIES’s research team revealed that Yeast is best alternate for fish meal due to its non-pathogenic, free of plasmid-encoded antibiotic resistance genes and resistant to bile and acidic pH.Hence, BIOSAC was formulated with yeast which is the most common single cell protein that can be incorporated within aquafeeds for shrimp and fishto efficiently minimize the need for protein of animal origin.
