Repurposing and reusing aquaculture wastes through a biosecure microfloc technology

Area of Science:

• Aquaculture
• Environmental Science
• Microbiology

Background:

• Intensive aquaculture generates significant waste, posing environmental challenges.
• Sustainable alternatives are crucial for the aquaculture industry's future.
• Biofloc technology (BFT) offers a novel approach to waste utilization.

Purpose of the Study:

• To review the microbial dynamics and bioremediation capabilities of Biofloc Technology (BFT).
• To highlight the role of metagenomics in understanding BFT's microbial communities.
• To discuss biosecurity and biocontrol aspects of BFT in aquaculture.

Main Methods:

• Review of existing literature on Biofloc Technology.
• Analysis of metagenomic studies identifying microbial communities in bioflocs.
• Examination of ecological interactions within the biofloc system.

Main Results:

• Bioflocs comprise diverse microbes (e.g., Cyanobacteria, Proteobacteria, Bacillus) crucial for waste mineralization.
• These microbes convert toxic compounds into nutrients, supporting fish and shellfish.
• BFT enhances water quality, reduces pollution, and improves aquaculture system efficiency.

Conclusions:

• Biofloc technology provides a biosecure, sustainable, and cost-effective solution for intensive aquaculture.
• It optimizes resource use, mitigates environmental impact, and enhances biosecurity.
• BFT represents a promising strategy for eco-friendly aquaculture production.
