Control of water quality is the key factor for a successful culture of aquatic animals
like fish, prawn and shrimp. An open water system with sufficient good water quality
may ensure successful aquaculture. However, if proper quality or sufficient quantity
of water is not available, purification of water by eliminating polluting substances
including toxic metabolites and growth inhibiting substances which originate mainly
form fish or shrimp excretion and excessive feed is necessary. Under these lower
water quality conditions there are chances for occurrence of mortalities by diseases
due to viral, bacterial, protozoal, fungal pathogens. High populations of aquatic
animals can be kept healthy under successful semi-closed and closed systems by
maintaining proper sanitisation. The increased demand in water quality and quantity
in shrimp and fish culture has resulted in a growing interest in using water sanitisers
and disinfectants.
