This study aimed to conduct a systematic review and meta-analysis evaluating the
inclusion of β-glucan in aquaculture animal diets and its impact on their health outcomes. Relevant studies were identified from Scopus and Web of Science databases.
A total of 82 primary studies published between 1996 and 2024 were reviewed, of
which 70 were included in the meta-analysis. The results revealed that the application
of β-glucan to aquaculture animal's diets significantly enhanced specific growth rate
(SGR; mean effect, g = 2.71; p < 0.001), feed conversion ratio (FCR; g = 3.88;
p < 0.0001) and lowered mortality after exposure to pathogens. Likewise, β-glucan
had a positive influence (p < 0.0001) on innate immune parameters (lysozyme and
phagocyte activity, NBT, ACH50, and IgM). The study found that the effects of
β-glucans varied among marine and freshwater fish where freshwater fishes
(g = 2.05–6.57) exhibit better performance. This study also found a negative correlation between fish's innate immune response and trophic level, suggesting that fish
with higher trophic levels may be less efficient at absorbing this bio-stimulant. Even
though there were high heterogeneity (I
2 = 73%–97%, p < 0.05) due to the diversity
of tested organisms and publication bias, our model and findings are valid. The findings suggest that the dietary application of β-glucans can have beneficial effects on growth and immune responses especially for freshwater species. The validity of these
observations needs to be confirmed by further prospective studies.
