Exploring fish microbial communities to mitigate emerging diseases in aquaculture

Area of Science:

• Aquatic microbiology
• Animal science
• Sustainable aquaculture

Background:

• Aquaculture is a rapidly growing global food sector crucial for feeding the human population.
• Disease outbreaks and the overuse of antibiotics pose significant threats to fish and shellfish cultivation.
• Current disease control methods are insufficient, necessitating sustainable alternatives.

Purpose of the Study:

• To review the diversity and functions of fish-associated bacterial communities.
• To explore the potential of beneficial microbes for disease mitigation in aquaculture.
• To highlight the importance of understanding fish microbiomes for sustainable aquaculture practices.

Main Methods:

• Next-generation sequencing techniques were employed to analyze fish bacterial communities.
• Literature review focusing on fish microbiome diversity, dynamics, and functions.
• Discussion of microbial functions and their role in host health and disease resistance.

Main Results:

• Next-generation sequencing has provided significant insights into the diversity and functions of fish bacterial communities.
• Beneficial microbes demonstrate potential for mitigating emerging diseases in aquaculture.
• A healthy fish microbiome is crucial for host growth and overall health.

Conclusions:

• Augmenting beneficial microbes presents a sustainable strategy for disease control in aquaculture.
• Further research into fish microbiome dynamics is essential for developing effective microbial interventions.
• Harnessing the power of the fish microbiome can reduce reliance on antibiotics and improve aquaculture sustainability.
