Is the Working Principle of Ecological Engineering Being Followed in Wastewater Fed Aquaculture?

There has been a paradigm shift towards reclamation of wastewater from high cost to low cost effective technology for treatment of sewage and resource utilization for economy driven activities.Under appropriate conditions, sewage fed fisheries would reduce the cost of fish production by utilizing the sewage induced natural plankton and become cost effective because of savings through chemical fertilizer and supplementary feed. It is conceived that concept of ecological engineeringis followed by the way of design and development of sustainable ecosystem for reclamation cum fish culture practices in waste stabilization pond systems. Living machines are also employed as tool for reclamation enhancement in wastewater pond system. However, further research are necessary to critically assess the pathogenic load of the fish grown in sewage fed ponds vis-a-vis, mode of transmission of bacteria and other parasites to fish farmers and the health risk of the fish-consumers who use them after proper cooking process.
