AQUACULTURE WASTES AS A RESOURCE: AN OVERVIEW
Keywords:
Aquaculture Waste, Circular Economy, Biofertilizers, Bioremediation, Sustainable DevelopmentAbstract
Aquaculture, a rapidly growing sector, produces substantial amounts of organic and inorganic waste, which, if not managed properly, can lead to environmental degradation. This review explores the potential of aquaculture wastes as valuable resources within a circular economy framework. The study focuses on various types of wastes, including fish feces, uneaten feed, and mortalities, and their potential applications in agriculture, energy production, and bioremediation. The current methods of waste management and their limitations, highlighting innovative approaches for converting these wastes into biofertilizers, biogas, and other bio-based products are analyzed. Emphasis is placed on the role of microbial processes and biotechnological advancements in enhancing waste valorization. Case studies demonstrating successful implementation of waste-to-resource strategies in different aquaculture systems are reviewed, providing practical insights and best practices. The paper also discusses policy implications and the need for integrated waste management strategies that align with sustainable development goals. By transforming aquaculture wastes into valuable resources, the industry can mitigate its environmental footprint while contributing to global food security and sustainable development. This review aims to offer an overview of the current state of research and to identify future directions for maximizing the potential of aquaculture wastes within a sustainable and resilient aquaculture system.
