   Abstract

   Inland aquaculture has rapidly expanded due to the world’s need for food and aquatic resources, which poses severe environmental sustainability obstacles. Intense aquaculture practices have worsened environmental issues in land and aquatic ecosystems, notwithstanding the green, blue, and silver revolutions’ breakthroughs that increased production in various industries. Some significant issues are nutrient enrichment syndrome, groundwater and soil salinization, mangrove destruction, biodiversity loss, and aquatic pollution. Concerns regarding the long-term sustainability of the fisheries and aquaculture sectors have also been sparked by overfishing, disputes amid players over the distribution of resources and space, and international trade disputes. These problems show how urgently aquaculture has to adopt sustainable practices. This chapter examines the important causes of the existing practices’ unsustainable nature and suggests solutions. It looks at crop rotation, wastewater-fed aquaculture, integrated culture systems, and the use of probiotics and premium feed to lessen environmental impact. Other crucial elements of sustainability include socioeconomic factors, moral issues, and legal frameworks, such as transboundary ecosystem management and fishery legislation. The chapter also emphasizes the significance of the conservation of natural resources, environmental impact assessments, and ethical fishing practices. In order to attain long-term sustainability, a recommended model describes feedback loops that incorporate selective pesticide usage, better farm management techniques, and policy tools. This thorough analysis aims to offer a road map for striking a balance between ecological integrity and productivity, guaranteeing that inland aquaculture can withstand the demands of global food security.

   G. Sri Bala, T. V. Nagaraju, G. V. R. Srinivasa Rao

   Abstract

   Inland aquaculture environments are manmade ecosystems in which water quality is a critical factor in defining the quality of aquatic products and the economic benefits of aquaculture. Inland aquaculture facilities are generally smaller, more susceptible to contamination, and have less capacity for self-purification than their sea counterparts. This chapter offers crucial theoretical and practical understandings of the vital role that water quality plays in inland aquaculture, with a focus on shrimp and fish productivity. We examine the ideal ranges for important water quality metrics, the operational requirements for preserving ideal water quality, and the significance of fertilizer delivery. There is a risk that White-leg (vannamei) shrimp farms, with their dense stocking, will surpass nearby habitat quality standards. The chapter also discusses ways to monitor water quality and manage diseases, emphasizing the value of continuing sustainable practices in inland aquaculture. This chapter seeks to advance sustainable inland aquaculture methods by highlighting the importance of careful water quality control.

   Abstract

   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.

   V. Chanakya Varma, G. Shyamala, G. Sri Bala, T. V. Nagaraju

   Abstract

   Inland aquaculture ponds in Asian countries saw an increase in aquaculture pond area and production with intensive farming activity. Therefore, the ammonia and nitrates produced by these intensive farming ponds may substantially impact global warming. Additionally, lower airways and interstitial lung illnesses have also been linked to acute exposures to high levels of ammonia. One more efficient approach is treating wastewater with biosorbents to remove ammonia. A quick, affordable, and environmentally beneficial way to remove ammonia from water is through biosorption. This work utilized biosorbents to remove ammonia from the aquaculture waters, specifically modified rice husk ash and corncob ash. Both biosorbents have been proven successful at removing ammonia from aquaculture waters. This paper also emphasizes how to utilize aquaculture waste sludge and shrimp processing waste in agricultural and construction industry, contributes to the waste-to-energy nexus. Adapting the methods mentioned above could help create sustainable inland aquaculture ponds for future generations. Additionally, social aspects of sustainability should be considered.

   Abstract

   India is the second-largest aquaculture nation in the world. The inland aquaculture is a rapidly growing coastal region of South India. For inland aquaculture, productivity majorly depends on environment, power, and water availability. The investment, maintenance, and risk involved should be minimized to enhance the economic aspects of inland aquaculture farming. The running cost of power for water pumping and aerators is becoming a burden for the farmers. The risks involved due to environmental conditions and water quality parameters should be predicted, and preventive measures should be taken to enhance farmers’ profits. Further, to minimize the effort of aqua labor and labor costs for farmers, automation should be made in aquaculture. To overcome these problems, this chapter proposes an Internet of Things (IoT) solution for aquaculture. The primary solution is a Photovoltaic (PV) based water pumping system. Its objective is to minimize the running cost for diesel-based water pumping systems, and for power-based, the number of units for electricity consumption can be minimized. The secondary objective is to detect and automate water quality parameters using IoT. These objectives minimize the risk and investment cost and enhance the farmers’ profit.
