Egypt is on the edge of sinking into an abyss of issues that will slow down the country's rebirth due to its current array of unresolved issues. One major issue is the lack of technological uses in agriculture. To address this challenge, agricultural and aquacultural feedback systems can be implemented.

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

Over the last decade, synthetic flocculants such as polyacrylamide, polyethylene amine, and aluminum sulfate have been widely used as flocculating agents in wastewater treatment process. Despite their effective flocculating activity, there are problems regarding their safety status in terms of high potential to cause carcinogenic and neurotoxic effects

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

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).

Biofloc Aquaculture: Guide for fish farmers
In contrast to RAS, where water treatment is carried out outside the culture column, biofloc technology is an in-situ water treatment technique that is a new development in fish culture systems that is moving towards assuring sustainable aquaculture (Vinatea et al., 2018).Dr. SAUGATA SASMAL +1 more
