Biofloc Application Using Aquaponics and Vertical Aquaculture Technology in Aquaculture: Review
This review examines biofloc technology as a sustainable aquaculture approach that uses microbial communities to improve water quality and reduce disease spread without requiring water exchange. Researchers discuss how integrating biofloc with aquaponics and vertical aquaculture systems can further enhance production efficiency. The study notes that while biofloc technology offers environmental benefits over traditional aquaculture, challenges like water quality fluctuations and microplastic contamination need to be addressed.
