About GrandPro
While probiotics for pond culture of shrimps are widely used, very few realise the critical need to produce quality, disease-free seeds in the hatchery — which is what leads to healthy shrimp in ponds. A good hatchery probiotic must address infections from luminescent Vibrios, ciliates, filamentous bacteria, and certain fungal species.
This is precisely where GrandPro excels. The antibacterial substances produced by one of the bacteria in the formulation have demonstrated excellent bactericidal properties (not antibiotics) against luminescent Vibrios — proven in field hatcheries.
🧬 Composition
GrandPro contains a specially blended mixture of different Bacillus species — selected specifically for hatchery conditions. No anaerobic bacteria that cannot work in the highly aerated hatchery environment, and no human pathogens such as Pseudomonas species.
