Webinar "Manajeman Penyakit dalam Budidaya Udang" Oleh Prof. Dr. Esti Handayani Hardi, S.Pi., M.Si

Summary

This video discusses innovative approaches in aquaculture, particularly focusing on the use of probiotics, prebiotics, and symbiotics to improve shrimp and fish health. The speaker explains how certain probiotics, like *Bacillus* strains, can enhance immune responses, suppress pathogen growth, and promote gut health in aquatic organisms. They also explore the potential of prebiotics to foster beneficial microbial populations. Additionally, alternative methods like using intermediate hosts to control parasitic infections are highlighted. The speaker emphasizes the role of biotechnology, including nanoparticle approaches, in advancing sustainable and effective aquaculture practices.

Takeaways

• 😀 Probiotics in aquaculture can reduce the growth of pathogenic bacteria by competing for nutrients and space, helping to maintain a healthy environment for aquaculture species.
• 😀 The extracellular and intracellular products of bacteria like *Aeromonas* and *Pseudomonas* can naturally inhibit each other's growth, showing potential for natural antagonistic behavior in aquaculture environments.
• 😀 Probiotics have shown the ability to improve the immune system of shrimp and increase their resistance to diseases by producing antimicrobial compounds.
• 😀 Bacteria in aquaculture systems can secrete toxins that naturally target and kill harmful microorganisms, contributing to a natural defense mechanism in aquatic environments.
• 😀 The application of probiotics in shrimp farming can be done orally or through immersion, with oral administration being particularly effective across all stages of shrimp development.
• 😀 Prebiotics, which are non-digestible carbohydrates, help support beneficial gut microbiota, enhancing immune responses and promoting the growth of healthy microorganisms.
• 😀 Symbiotics, a combination of probiotics and prebiotics, are used to improve gut microbiota composition and overall health in farmed organisms.
• 😀 Research in Indonesia and other countries has shown the benefits of using nano-particles and biotechnology to combat pathogens in shrimp farming, offering promising approaches for disease management.
• 😀 The use of probiotics and prebiotics in aquaculture can reduce the need for chemical treatments, supporting more sustainable and eco-friendly farming practices.
• 😀 The natural microbial antagonism observed in aquatic environments suggests that native bacteria could play a significant role in controlling disease outbreaks in aquaculture without the need for synthetic additives.

Q & A

What is the significance of the extracellular and intracellular products in *Aeromonas* and *Pseudomonas* bacteria?

The extracellular proteins produced by *Aeromonas* and *Pseudomonas* bacteria can inhibit each other. This interaction suggests that probiotics might help reduce the growth of harmful bacteria by competing for resources, which could be beneficial in aquaculture for disease prevention.

How do probiotics contribute to disease reduction in shrimp farming?

Probiotics in shrimp farming can help reduce disease by competing with pathogenic bacteria for growth resources. This competition reduces the population of harmful bacteria, thus decreasing the risk of infections in the shrimp.

What are some of the benefits of probiotics for shrimp health?

Probiotics can enhance shrimp health by increasing non-specific immune responses, producing antimicrobial substances that inhibit pathogens, aiding in digestion, and competing for nutrients to maintain a balanced microbial environment.

What methods of probiotic administration are mentioned for shrimp?

Probiotics can be administered orally, which is effective for shrimp at all stages of development. Additionally, soaking treatments are effective for juvenile shrimp.

What is the role of prebiotics in shrimp farming?

Prebiotics, which are undigestible carbohydrates like monosaccharides and oligosaccharides, support the growth of beneficial gut microbes by interacting with immune receptors and improving immune function. They help maintain a healthy gut microbiota in shrimp.

How do symbiotics differ from probiotics and prebiotics in shrimp farming?

Symbiotics are a combination of probiotics and prebiotics. They work together to improve the health of shrimp by enhancing gut microbial colonization and supporting the growth of beneficial microorganisms, thus boosting the immune system and overall health.

Can you provide examples of probiotics used in shrimp farming?

Examples of probiotics used in shrimp farming include strains of *Bacillus*, which can be found in the shrimp's gut or in the surrounding water. These probiotics help in controlling harmful bacterial growth and improving shrimp health.

What are some prebiotics that have been used for shrimp?

Prebiotics such as inulin and mannan oligosaccharides are used in shrimp farming. These prebiotics help in immune modulation and enhancing the overall gut health of shrimp.

How can nanotechnology and biotechnology contribute to shrimp farming?

Nanotechnology and biotechnology can help combat pathogens in shrimp farming by improving the effectiveness of probiotics, prebiotics, and other biotechnological tools. These approaches have been successfully developed both in Indonesia and globally.

What innovative methods have been suggested for controlling parasitic worms in shrimp farming?

For controlling parasitic worms in shrimp farming, one method involves using intermediate hosts like algae or seagrass to break the parasitic cycle. These hosts can serve as a place for worms to complete their life cycle before the contaminated plants are removed.
