Probiotics for coral aquaculture: challenges and considerations

Area of Science:

• Marine Biology
• Microbiology
• Conservation Science

Background:

• Coral reefs are declining globally due to climate change and cumulative impacts.
• Active interventions, including coral restoration, are crucial for mitigating these declines.
• Coral aquaculture offers a scalable solution for reseeding reefs and potentially selecting stress-tolerant corals.

Purpose of the Study:

• To explore the potential of probiotics in enhancing coral aquaculture for reef restoration.
• To identify beneficial probiotic traits for coral health, stress tolerance, and nutrition.
• To outline research directions for developing and verifying probiotics in industrial-scale coral aquaculture.

Main Methods:

• Review of coral-associated bacteria and their role in the coral holobiont.
• Identification of probiotic characteristics beneficial for coral health.
• Discussion of research needs for probiotic application in coral aquaculture.

Main Results:

• Coral-associated bacteria play a vital role in the coral holobiont.
• Probiotics can potentially confer benefits like disease resistance, enhanced environmental tolerance, and improved nutrition.
• Further research is needed to validate probiotic efficacy for large-scale coral aquaculture.

Conclusions:

• Probiotics show promise for improving coral aquaculture and supporting reef restoration efforts.
• Targeted research is essential to develop and implement effective probiotic strategies.
• Successful application of probiotics could significantly aid in conserving coral reefs globally.
