Biofloc Technology in Fish Aquaculture: A Review

Abstract

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.

Swinging between the beneficial and harmful microbial community in biofloc technology: A paradox

“…In a biofloc closed system, certain species of microorganisms play a crucial role in maintaining water quality and promoting the growth and health of the culture animals. Innovative aquaculture systems using BFT have been applied to many fish farms due to increasing concern about environmental pollution [ 6 ]. Heterotrophic bacteria in BFT assimilate inorganic nitrogen and synthesis them into useful energy-rich bio-materials for the trophic utilization of the cultured animals [ [7] , [8] , [9] , [10] ], consequently detoxifying the culture system of the deleterious waste generated from the fecal pellets and unconsumed feeds left in the water medium.…”

Design, development, and deployment of a sensor-based aquaculture automation system

“…The aquaculture industry, set to grow at a 7.5% CAGR from 2020 to 2027, has seen the shrimp market valued at USD 45.9 billion in 2019, projected to reach USD 68.9 billion by 2027 with a CAGR of 5.2%. The industry has adopted innovative practices, such as bio oc farming, online monitoring, pond optimization, probiotics, and automation, for sustainable and pro table shrimp cultivation (Das et al 2022;Yu et al 2023). However, challenges persist in shrimp grow-out ponds owing to uctuating environmental factors, poorly understood nutrient cycling, and wastewater management issues, resulting in suboptimal growth rates.…”

Impact of Organic Carbons Addition on the Enrichment Culture of Nitrifying Biofloc from Aquaculture Water: Process, Efficiency, and Microbial Community

“…Over the past decade, BFT has been widely studied and applied in aquaculture for many shrimp and fish species [18,19]. In practice, significant rises of NH 4 + -N and NO 2 − -N and an uncertain duration of their peaks are often observed when applying BFT in the intensive aquaculture systems [14,15,17,20].…”
