abstract
The growth of the aquaculture industry is gaining momentum day by day. The ever-increasing population, required food and nutritional security from the limited available resources viz. land and water magnifying the problems of diminishing productivity. The indiscriminate use feed, chemicals (aqua inputs) results in increasing pollutants led to producing significant amounts of wastes, including metabolic by-products which are responsible for making the situation more worsen. In today’s scenario, the focused must be on the productivity of the resources instead of production. To increase the productivity of the affected land and water one must found the sustainable way of treatment, in this context bioremediation is an innovative approach which is safe and less costly compare to the existing ones. In this technique, the use of live microbes is employed in the degrading the complex pollutants or harmful waste into simple and harmless products. The use of these microbes (bacteria’s) not only improve the water quality but also promoting the health aspects of the culture organisms and thus maintaining the sustainability of aquaculture ecosystems. Bioremediation plays a significant role in aquaculture and actively participated in the process of mineralization of complex organic load into simpler forms which can be assimilated by the planktons and improve the primary productivity of the system. Further, the bioremediations agents (heterotrophic nitrifying and denitrifying microbes) plays a significant role in nitrification and denitrification process to remove unwanted nitrogen compounds and contribute to improving the overall health of the pond ecosystem.
