Probiotics are widely used in commercial shrimp aquaculture, but responses are variable. The objectives of this study were to quantitatively review using meta-analysis the production, survival, and immune responses of Macrobrachium rosenbergii to probiotics (Lactobacillus or Bacillus) and to identify sources of residual variation.

💡 The results indicate that interventions with probiotics in M. rosenbergii improved growth performance and survival, may be influenced by probiotic agents, and are likely to lead to economic benefits for industry.

📌 Research Highlights:
▶Probiotics improved the specific growth rate in M. rosenbergii.
▶Feed to gain was improved with probiotics in M. rosenbergii.
▶Variation in the response of M. rosenbergii to probiotics was largely attributable to study conduct.
▶Covariables rarely explained variation in response of M. rosenbergii to probiotics.
▶Probiotic agent may influence outcomes in M. rosenbergii.

🎯 Probiotics can be an effective way at increasing the health and production of giant freshwater prawns. A focus of our work here at Regen Aquaculture has been to further explore the cultivation of low-cost highly effective microbial inoculants and biostimulants on-site.  Interested in learning how to cultivate your own microbes?
