The rapidly expanding field of inland aquaculture has several obstacles relating to water management, such as environmental impact, resource sustainability, and quality monitoring. Inland aquaculture, particularly shrimp culture, relies on the brackish environment and discharge of these waters that are unsuitable for crops or human consumption. Since most developing nations shrimp culture farming practices include water changes for every one or two crops without any treatment, Because of the high nutrient load, untreated aquaculture water should be treated and reused for the following crop rather than released into neighbouring canals. An essential component of sustainable aquaculture farming is water management in the pond. The management of pond water with modern innovations is covered in this chapter. Furthermore, this chapter explored sustainable methods like feed management, built wetlands for wastewater treatment, and recirculating aquaculture systems (RAS). The practical application of these techniques is demonstrated by case studies from numerous international aquaculture enterprises, which show increased aquaculture productivity, decreased environmental impact, and improved water use efficiency. Aquaculture can attain increased sustainability by using these cutting-edge water management strategies, guaranteeing the long-term survival of this vital sector.
