The increase in aquaculture activities around the world has had a significant impact on food utilization. Intense inland aquaculture is becoming increasingly necessary to maintain protein supplies as natural sources like lakes and reservoirs reach their limits in producing shrimp. Leading nations in this field, South Asia uses various techniques to increase shrimp harvests. However, toxic substances in aquaculture wastewater, such as pesticides, leftover feed, antibiotics, and shrimp waste, raise questions since they might hurt the environment when released. Extensive research has been conducted to create efficient aquaculture effluent treatment techniques to overcome these problems. The recirculating aquaculture system (RAS) is frequently employed in Western countries; low-cost phytoremediation techniques are less prevalent in inland aquaculture even though they are in vogue in industrial treatments. This study examines the body of research on the phytoremediation of wastewater worldwide between 2000 and 2023, using bibliometric and textual analysis to identify trends. The findings show a consistent rise in publications, particularly beyond 2020, with China and India contributing the most. Since 2000, initiatives have been made to preserve and improve the environment, with a particular emphasis on techniques such as artificial wetlands and RAS. Biological remediation techniques have received more attention lately, with phytoremediation emerging as the most successful method. In order to improve remediation capabilities and support sustainable inland aquaculture, this report summarizes the literature and offers recommendations for future research.
