Dietary administration of yeast (Saccharomyces cerevisiae) hydrolysate from sugar byproducts promotes the growth, survival, immunity, microbial community and disease resistance to VP in Pacific white shrimp (Litopenaeus vannamei).

This study investigated the effects of yeast hydrolysate (YH) from sugar byproducts on various parameters in Pacific white shrimp (Litopenaeus vannamei). The study found no significant differences in water quality parameters across all treatment tanks, ensuring that the observed effects were not due to environmental variations. There were no significant differences in growth parameters between the control group and groups receiving YH at different dosages.

Effects of ribonucleotide supplementation in modulating the growth of probiotic Bacillus subtilis and the synergistic benefits for improving the health performance of Asian seabass (Lates calcarifer).

In aquaculture, due to the requirements for high-density culture, the diseases caused by bacterial pathogens have become a serious issue. To solve this problem, we performed synbiotic application of RNA and Bacillus subtilis as a sustainable and eco-friendly approach to improve the health and immunity of Asian seabass (Lates calcarifer) during cultivation without using any harmful antibiotics or chemicals. Among various forms of nucleic acids, such as mononucleotides and DNA, RNA was found to be most effective in promoting the growth performance of probiotic B.
