This research aimed to elucidate the effect of Chlorella sp. addition on biofloc quality and growth of Macrobrachium rosenbergii juveniles in biofloc systems. Four treatments of freshwater prawn nursery culture systems were tested, i.e., control system with clear water system at a regular water exchange at about 50% every 2 weeks; control system with ...

The structure of microbial communities in a biofloc Technology (BFT) system has a great influence on the optimal functioning of the system. This makes understanding the microbial composition in BFT of paramount importance. A study was conducted to characterise the microorganisms in an indoor biofloc technology system.

Nitrate accumulation in biofloc aquaculture systems
Aquaculture, 2020Abstract Minimizing ammonium is one of the most important concerns in the practice of aquaculture. Chemoautotrophic bacterial nitrification (CBN) and heterotrophic bacterial assimilation (HBA) are the two main ammonium pathways in aquaculture water under light-limited conditions. CBN oxidizes ammonia–nitrogen (NH4+-N) to nitrite–nitrogen (NO2−-N) and

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

This study investigated the effects of biochar application on the bacterial community structure in bioflocs and intestines of Oreochromis niloticus cultured in a biofloc system and further evaluated its effects on some intestinal enzyme activities. Three carbon treatments, the control G, sole application of glucose; B, sole application of biochar; and ...

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).

Bacteria in biofloc technology aquaculture systems: roles and mediating factors
Reviews in Aquaculture, 2022AbstractThe abundance of nitrogen compounds, phosphorous compounds and organic matter in biofloc technology (BFT) aquaculture systems creates an ideal medium for increasing microbial communities and load. The abundance of microbial DNA found in BFT aquaculture systems is hypothesised to be among the greatest in current aquaculture systems.

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 ...
