Description

1. An interesting example of this system type was so-called Biofloc, which consist of developing microbial aggregates formed from carbon:nitrogen ratio (C:N) in water, with low or zero exchange and high oxygenation, diets with low crude protein content and external carbon source like molasse (sugar cane), rice bran, wheat bran, among others. This C:N ratio allows microbial community growth, especially of heterotrophic bacteria, which metabolize carbohydrates and consume inorganic nitrogen (principally ammonia NH4 +), reducing their concentration and improve water quality .

2. Biofloc technology (BFT) is one of the innovative methodologies for waste management and nutrient retention that offers a solution to solve environmental problems in aquaculture because it doesn’t use water exchange to solve nitrogen compound elimination, but it utilizes microbial assimilation, stimulated for addition of material rich in carbon, to transform those compounds. Also, microbial protein can be used as food for culture species . This is very important because in any fish and crustacean culture system, water quality management is the principal factor that impacts in production sector, particularly in intensive and hypertensive culture systems

3. In conventional fish and crustacean culture systems, the nitrogen compounds transformation is made by autotrophic microorganisms of Nitrospira, Nitrobacter and Nitrosomonas genders. However, an excess of organic matter in form of carbon, inhibit their efficiency by limiting their growth [34]. Contrary, in Biofloc systems, nitrogen compounds transformation is more efficient, because this process is made by facultative heterotrophic bacteria that correspond principally to Bacillus and Pseudomonas gender. These two genders are more efficiently in organic matter presence, which allow increasing their population abundances quickly and oxide-reduction process .

4. Effectively degrades all types of organic wastes in the pond like excess feed, faecal matter, exoskeletal moults and keeps the pond clean.

5. Reduced Vibrio and other bacterial disease problems- Healthier ponds

6. ,zero water exchange
