Does the biofloc size matter to the nitrification process in Biofloc Technology (BFT) systems?
Aquaculture, 2019Abstract In addition to environmental factors, particle size can interfere with the nitrification process because smaller flocs are less efficient in terms of ammonia and nitrite oxidation. The objective of the present study was to evaluate, in three experiments, the effect of the biofloc size on the nitrification process during the production of the

Abstract The present study evaluated the use of a biofloc system (BFT) for the larviculture of goldfish (Carassius auratus). Two experiments were carried out, of which the first evaluated two culture systems (BFT and clear water) and three densities of Artemia nauplii (100, 200 and 300 nauplii larvae−1).

Abstract The current study evaluated the effect of a carbohydrate addition strategy set at two biofloc levels on the establishment of nitrification in new biofloc technology aquaculture systems. Three carbohydrate addition strategies were chosen as follows: one-time glucose addition with 20:1 of the input C/N ratio, glucose additions at a C/N ratio ...

Impacts of Nile Tilapia (Oreochromis niloticus) exposed to microplastics in bioflocs system
Science of The Total Environment, 2023Microplastics (MPs) are abundant in aquaculture water, including in bioflocs aquaculture systems. Compared with other aquaculture systems, biofloc technology systems have the richest microbes and are beneficial to cultivated organisms. Therefore, this study provides a comprehensive assessment of the potential effects of MPs on aquaculture organisms in ...

The nitrification process for nitrogen removal in biofloc system aquaculture
Reviews in Aquaculture, 2020AbstractAquaculture is an economic activity that faces the unavoidable problem of water quality detriment, which is mainly generated by the improper management of production ponds, including inadequate water circulation and aeration, accumulation of undigested food residues, excretion of metabolic by‐products by the cultivated organisms and other.

A 25-week experiment was conducted to investigate the changes in the microeukaryote community (MEC) and nutritional composition of the biofloc during Nile tilapia culture in water-reusing biofloc systems. The study evaluated two treatments: tilapia culture in biofloc (TB) and tilapia culture in biofloc with reuse water (RWTB).

Evaluation of floc-harvesting technologies in biofloc technology (BFT) system for aquaculture
Bioresource Technology, 2020This study was conducted to examine floc-harvesting performance by three separation technologies, namely sedimentation, centrifugation, and membrane filtration, for biofloc generated from a BFT system in aquaculture. According to the experimental results, sedimentation demonstrated the poorest harvesting performance with the lowest energy consumption ...

Abstract Biofloc technology involves manipulation of the C/N ratio to convert toxic nitrogenous wastes into useful microbial protein and helps improve the water quality in a closed system. Poly-β-hydroxybutyric (PHB) has been demonstrated to have positive effects on aquatic animals in an aquaculture system. A 40-day lab scale trial was carried out to
