Aeration with atmospheric air and perhaps supplemental compressed or liquid oxygen. Supplemental oxygen can be incorporated into venturi aspirators or diffuser stones. Above 40C there is chance of floc to die.

Biofloc systems require up to 6mg of oxygen per litre per hour and it is recommended to start with at least 30 horsepower of aerators per hectare. If you dont have good knowledge of aeration pumps and dissolved oxygen requirements in your Biofloc System you can help you with that. We have been in Biofloc System for a while now and understand which aeration pumps can give how much dissolved oxygen in the Biofloc System.

Whereas 4 ton biomass of fish will need 1 HP of blower and 25 metre of AirOxi tube. Oxygen additions may be combined with the need to keep biofloc in suspension. The basic requirements for biofloc system operation include high stocking density with 130-150 PL10m2 and high aeration of 28 to 32 hpha with correct paddlewheel position in ponds.

But depending on the intensity and productivity of the system this number can reach as high as 200 horsepower per hectare See table 1 from the Southern Regional Aquaculture Center further on. Due to the elevation of water respiration rates the response time is reduced remarkably. Ponds must be lined with concrete or high-density polyethylene HDPE and pel-leted grain and molasses are added to the culture water.

Thus high volume of water can be pushed using a relatively low pressureTemperature in Biofloc fish farmingFor fish farming in Biofloc ideal temperature is 20C to 40C Below 20 C less chance of floc formation Some bacteria can grow in 15 C also. Aeration in Biofloc Fish pond. Readings should be taken at least once weekly.

The requirements for Biofloc system operation have a high stocking density of about 130 to 150 PL10m2 10 post larvae PLs per square meter and high aeration of 28 to 32 horsepower per hectare hpha with correct paddlewheel position in ponds.
