EM use in Aquaculture
EM is ideally suited for use in pond based aquaculture systems. Not only will the EM help to maintain the water quality, but will also the breakdown of waste and sludge on the pond floor. If EM is used, both growth rates and fish help is significantly improved.
If added to fish feed, EM has been proven to boost the immune system of fish. Download Research
EM is also ideally suited for use in recirculating systems, as the EM will increase the efficiency of biological filters, especially if used in conjunction with EM ceramics. BOD levels will be significantly reduced.
If reed beds are incorporated into a fish farms as part of its pollution control protocol, EM will again boost the efficiency of the system helping to reduce BOD & COD.

EM ceramics mentioned above come in two forms, rose and grey and are ideal for closed systems. They will help maintain the water quality and control odours by consuming the waste products produced by the fish - both organic and chemical, including ammonia (excreted by fish through their gills), CO2 and hydrogen sulphide - all of which are toxic to fish if allowed to accumulate.
The grey EM ceramics improve the structure of the water, enabling the EM microbes to work more efficiently, however they do not remove any waste products from the water. These have a life span of around 10 years.
The rose EM ceramics actively consume the waste that comes in contact with they won't become clogged, however they will only remain effective for 6 months.
EM ceramics are used at 1 part:1000 parts water (1 Kilo/CuM) - but if used in an enclosed system, the quantity required can be reduced by 20%.
