6.1.5. Bioremediation in aquaculture systems

The recent approach to improve water quality in aquaculture is the application of microbes/ enzymes to the ponds, known as ‘bioremediation’.

• Bioremediation involves manipulation of microorganisms in ponds to enhance mineralization of organic matter and get rid of undesirable waste compounds and there by toxic effect.
• When macro and micro organisms and/or their products are used as additives to improve water quality, they are referred as bioremediators or bioremediating agents (Moriaty, 1998).
• The isolation and development of indigenous bacteria are required for successful bioremediation.
• The administration of beneficial bacteria in the culture water has emphasized two advantages: bioremediation for controlling water quality and biocontrol with the goal of being antagonistic to pathogens.
