Abstract
Aquaculture production has increased steadily in recent years and is the fastest growing food production sector and has become a valuable component of national development and poverty reduction plans in many areas of the world. Aquaculture is now considered as a potential polluter of the aquatic environment and a cause of degradation of wetland areas. To reduce the environmental damages caused by aquaculture, the alternative technology available is to optimize production with the usage of the “biofloc technology (BFT)”. Biofloc applies to a complex structure made out of 60 to 70% of organic matter, which includes a heterogeneous mixture of microorganisms (fungus, algae, protozoans, and rotifers) and of 30 – 40% of inorganic matter such as colloids, organic polymers, and dead cells. Nearly all biofloc systems are used to grow shrimp, tilapia and carps.
