During the Biofloc method, fish are reared in modest tanks of about 4 meters in diameter using a ability of about 600 fish. In addition to the fish, a culture of heterotrophic bacteria is also developed with them. The set up also calls for aeration and mixing mechanisms to stability the oxygen supply and thoroughly perform the heterotrophic bacterial society.
There’s much more to biofloc than satisfies the eye. The system demands a startup interval and yields aren’t constantly steady amongst seasons. Due to the fact producers have to continuously mix and aerate society water, Electricity costs could possibly be larger than envisioned.
