How Biofloc is useful in fish farming?

In the aquaculture system, the strong influential factors are the feed cost and the limiting factors is the water or land availability and high stocking density and rearing of aquatic animals require wastewater treatment.

The problem of extensive fish culture in ponds is to keep the water quality and before bioflocs way was to recycle 10 % of the water frequently. But in some places, Water is not present in abundance and replacing the old water with a new one disturbs the growth of fish. So, Biofloc came to solve all these difficulties.
