Fermentation Technology in Aquafeeds: A Review

Area of Science:

• Aquaculture Nutrition
• Animal Feed Science
• Microbial Fermentation

Background:

• Fermented feed is a functional feed that improves nutrition and palatability via microbial fermentation.
• It addresses digestive and immune issues in aquaculture animals and reduces reliance on fishmeal.
• Challenges include limited industrial production and research on crustaceans.

Purpose of the Study:

• To provide a narrative review of fermented feed in aquaculture.
• To summarize the benefits, types, and influencing factors of fermented feed.
• To highlight its positive effects on growth, immunity, gut microbiota, and product quality.

Main Methods:

• Narrative literature review of fermented feed.
• Synthesis of existing research on fermented feed applications in aquaculture.
• Identification of benefits, challenges, and future research directions.

Main Results:

• Fermented feed enhances nutritional value and palatability through microbial fermentation.
• It promotes growth, boosts immune response, optimizes intestinal microbiota, and improves product quality in aquaculture animals.
• Key benefits include mitigating digestive and immune dysfunction.

Conclusions:

• Fermented feed offers significant potential to reduce costs and improve efficiency in aquaculture.
• Further research is essential for database development, intelligent manufacturing, and economic evaluations.
• Expanding research to crustaceans is crucial for broader application.
