Abstract

Aquaculture is becoming a key source of affordable animal protein worldwide. It is also viewed as a sustainable alternative to wild fisheries, which are declining due to overfishing. As the global population grows, the demand for seafood increases, leading to more intensive aquaculture practices. However, this expansion generates various effluents that can harm natural water resources. Traditional treatment methods have struggled to manage the growing number of contaminants effectively. This chapter introduces advanced technologies for treating aquaculture effluents. These include cavitation, high-rate algal pond systems, nanomaterials, Advanced Integrated Wastewater Pond Systems (AIWPS), constructed wetlands and the Sheaffer Modular Reclamation and Reuse System. These innovative methods are increasingly used to improve wastewater management in modern aquaculture operations.
