A new piece of research published in Animals showed that yeast had a significant impact on the growth of rainbow trouts in a 60-day trial. The study combined S. cerevisiae and thymol, a compound derived from thyme. The main takeaways also show better immunity and antioxidant indicators. This discovery points at the potential of more natural additives for aquacultures.
Together, thymol and S. cerevisiae had an increased impact on fish health. The
growth of treated trout was 348%, compared to 296% for the control group. As the aquaculture industry faces challenges like disease outbreaks and environmental pressures, yeast stands as a useful, more natural alternative to synthetic products and antibiotics.
