Water
Oxygen and ammonia are the two most important parameters in aquaculture operations. While oxygen can be easily controlled ammonia on the other hand is much more difficult to mitigate and is highly detrimental to the health of fish. The natural generation of toxic levels of ammonia (NH3) and hydrogen sulphide (H2S) by large densities of fish in aquaculture operations affects fish tissue, growth rates, oxygen utilization, disease resistance and causes mass mortality.
