Microbial research in aquaculture focuses on understanding the role of microorganisms in maintaining the health and productivity of aquatic species. Beneficial microbes, such as probiotics, can help prevent disease, improve digestion, and enhance the immune response of farmed fish. Conversely, harmful microbes can lead to outbreaks of diseases that threaten fish populations. Researchers are exploring ways to harness beneficial microbes and microbial communities to improve the health of farmed species while minimizing the use of antibiotics and chemicals. This research is vital for creating sustainable and resilient aquaculture systems that reduce environmental impacts and improve the efficiency of production.
