Introduction

The study investigates the protective efficacy of a beta-glucan-enriched diet on Nile tilapia (Oreochromis niloticus) against infection by Aeromonas hydrophila. Given the increasing popularity of tilapia in aquaculture and its significance for rural economies, there is a need to enhance fish health and growth performance in farming practices. The research indicates that dietary supplementation with beta-glucans can stimulate immune responses, improve disease resistance, and enhance growth metrics in Nile tilapia.

Immunostimulant Effects of Beta-Glucans

Beta-glucans are polysaccharides found in the cell walls of various organisms, including bacteria and fungi, known for their immunostimulatory properties. The study highlights that beta-glucans can increase fish immune responses, thus providing protection against pathogens like Aeromonas hydrophila. The results demonstrated that fish fed diets enriched with beta-glucans exhibited higher survival rates when exposed to bacterial challenges, particularly with those receiving 1% beta-glucan, achieving a 100% survivability rate compared to unprotected groups.

Growth Performance Improvement

The research also focuses on the growth performance of Nile tilapia fed with varying concentrations of beta-glucans. The findings indicated significant increases in body weight, weight gain, and overall feed conversion efficiency in groups with dietary supplements compared to the control group that did not receive beta-glucans. Specifically, the group receiving 1% beta-glucan showed the best growth metrics, emphasizing the positive correlation between beta-glucan supplementation and enhanced growth performance in farmed tilapia.

Hematological and Biochemical Benefits

In addition to growth performance, the study explored the biochemical and hematological parameters associated with beta-glucan supplementation. Notably, there was a significant increase in total leukocyte counts, lysozyme activity, and immunoglobulin M (IgM) levels in the fish fed with beta-glucans, indicating enhanced immune competence. Furthermore, the health of the liver and kidneys was assessed through serum biomarkers, and the results suggested that beta-glucans could mitigate the harmful effects of infections while supporting overall fish health.

Conclusion

The results of the study conclude that dietary supplementation with beta-glucans can significantly enhance immune responses, growth performance, and overall health in Nile tilapia. This dietary strategy presents a viable approach to improving fish farming practices, ultimately leading to increased productivity and economic returns. As aquaculture continues to evolve, incorporating immunostimulatory agents like beta-glucans offers potential benefits for sustainable fish farming and can help mitigate challenges posed by prevalent aquatic pathogens.
