Disease prevention in aquaculture
Disease management and prevention has become one of the top priorities for the aquaculture industry. This is due partly to economic losses, caused by disrupted production, and partly to sustainability issues and increased pressure to reduce the use of antibiotics and chemicals. The risks associated with drug resistant pathogens, environmental impacts, and consumer perceptions of antibiotic residues in farmed products, are notably the sector’s main concerns.
Preventing pathogenic bacteria outbreaks requires planned and integrated action, including strict biosecurity protocols, improved aquaculture practices, genetic selection, vaccines, and the use of functional feed additives.
Yeast-based solutions for aqua feed are known to be a highly effective and cost-efficient tool. Yeast parietal fractions, rich in beta-glucans 1.3 and 1.6 and mannan-oligosaccharides, can directly improve innate immunity, reduce pathogen attachment to the gut epithelium, bind toxins and improve gut structure and function.
