In the bustling world of aquaculture, where innovation meets necessity, a groundbreaking study has emerged from the labs of Bogor Agricultural University, offering a promising solution to one of the industry’s most pressing challenges: disease management. Muhamad Gustilatov, a researcher from the Department of Aquaculture at the Faculty of Fisheries and Marine Sciences, has been delving into the potential of biofloc systems supplemented with beneficial bacteria to bolster the health and productivity of Pacific white shrimp (Penaeus vannamei).
The study, published in Comparative Immunology Reports, explores the impact of biofloc density and Bacillus sp. NP5 supplementation on bacterial inhibition, antibiofilm activity, and the immune response of shrimp against the notorious pathogen Vibrio parahaemolyticus. The findings could revolutionize shrimp farming practices, particularly in regions where disease outbreaks pose significant threats to commercial operations.
Gustilatov’s research focuses on the use of biofloc technology, a system that leverages microbial communities to improve water quality and nutrient management in aquaculture settings. By supplementing biofloc with Bacillus sp. NP5, a beneficial bacterium known for its antimicrobial properties, the study aims to enhance the shrimp’s natural defenses against pathogenic bacteria.
The experiment involved rearing shrimp in aquariums with varying biofloc densities—5, 10, and 15 mL/L—and challenging them with V. parahaemolyticus. The results were striking. While all biofloc treatments showed improved growth performance compared to controls, the 15 mL/L biofloc density stood out by significantly reducing the pathogen’s density and biofilm formation. This density also boosted the shrimp’s immune responses, as evidenced by increased total hemocyte count, phagocytic activity, respiratory burst, and phenoloxidase activity.
“Biofloc supplemented with Bacillus sp. NP5 significantly improved shrimp health and productivity,” Gustilatov explained. “The 15 mL/L biofloc density provided optimal pathogen reduction and immune enhancement, which could be a game-changer for the aquaculture industry.”
The implications of this research are far-reaching. For the energy sector, which often relies on aquaculture for sustainable protein sources, this study offers a viable strategy to enhance disease resistance and productivity. By integrating biofloc systems with beneficial bacteria, farmers can reduce the need for antibiotics, lower operational costs, and ensure a more sustainable and resilient shrimp farming practice.
As the aquaculture industry continues to evolve, the adoption of such innovative technologies will be crucial. Gustilatov’s work, published in Comparative Immunology Reports, translates to Comparative Immunology Reports, sets a precedent for future research and development in the field. It underscores the importance of exploring microbial interactions and their potential to revolutionize aquaculture practices.
The study’s findings suggest that the future of shrimp farming lies in harnessing the power of beneficial microorganisms. As researchers and industry stakeholders continue to explore these avenues, the prospects for a more sustainable and productive aquaculture sector become increasingly bright. The journey towards a disease-resistant and high-yielding shrimp industry is well underway, and the path is paved with microbial innovation.
