Biofloc Technology in Fish Aquaculture: A Review
Summary
This review examines biofloc technology, a method of fish farming that uses beneficial microbial communities to improve water quality and fish health. While not directly about microplastics, the technology is relevant because it could reduce the environmental footprint of aquaculture and potentially limit fish exposure to waterborne contaminants. Healthier aquaculture practices may help produce safer fish for human consumption in an era of increasing water pollution.
The application of biofloc to fish species has several advantages, including the enhancement of production by increasing growth performance and survival rate and the improvement of fish aquaculture physiological activity. There has been a recent increase in biofloc addition to fish culture, and this review examines changes this causes to the survival and growth rate of fish and its economic feasibility. Physiological activity and disease resistance of biofloc-fed fish is being extensively studied. The hematological parameters and antioxidant and immune responses of fish fed biofloc were reviewed in this study, as well as their disease resistance by testing them for major specific diseases. Standards for effectively applying biofloc to fish aquaculture are also suggested.
