Aquaculture is widely recognized as a vital resource for satisfying nutritional security and livelihood options for the growing world population when the capture fishery resources are stagnating. Although aquaculture started with traditional farming models, the spiraling demand for quality protein sources to meet the ever-increasing population resulted in a paradigm shift from conventional to semi-intensive or intensive farming. Intensification in aquaculture nevertheless doubled the income with better nutritional security; the sector started to face myriad challenges, such as eutrophication, single species-oriented culture, the escalating price of fish meal and feed ingredients, disease outbreaks, antibiotic residue, traceability, etc. This social and environmental insecurity urgently calls for farming practices that are economically profitable to meet the growing demand for food and eco-friendly to ensure future sustainable aquaculture production. Sustainable integrated aquaculture considerably differs from extensive or intensive stand-alone farming models as it integrates ecosystems with diversified species having different trophic levels. Thus, this farming system can reduce the risk associated with intensive monoculture, disease outbreaks, price volatility of aquatic products, etc. As these farming models have better synergism and are environmentally sound, they can be considered a panacea for small-scale farmers in developing countries. The majority of sustainable aquaculture embraces the age-old integrated agriculture-aquaculture farming models, such as paddy-cum-fish culture, livestock-cum-fish culture, etc. Due to technological advancement, many farming models, such as recirculatory aquaculture (RAS), integrated multitrophic aquaculture (IMTA), biofloc-based farming system (BFT), polyculture, etc., integrate sustainability in intensification and are gaining popularity among the farming community and stakeholders due to their multiple advantages.
