Abstract:
Aquaculture, the farming of fish and other aquatic organisms, has become an essential component of the global food supply. However, the rapid expansion of aquaculture has led to significant environmental concerns, primarily due to the management of aquaculture waste. This article provides a comprehensive review of the current state of aquaculture waste management, focusing on innovative solutions and best practices to mitigate the environmental impact of aquaculture operations.

Introduction:
Aquaculture has experienced substantial growth in recent decades, driven by increasing global demand for seafood. This growth, however, has raised concerns about the environmental sustainability of aquaculture practices. One of the primary issues is the management of aquaculture waste, which can include uneaten feed, fish excreta, and dead fish. Inadequate waste management can lead to water quality degradation, eutrophication, and the spread of diseases. This review aims to explore innovative approaches to aquaculture waste management, highlighting recent advancements and best practices.

Conclusion:
Aquaculture waste management is a critical aspect of ensuring the environmental sustainability of aquaculture operations. Innovative solutions and best practices are essential to mitigate the negative impacts of aquaculture waste on the environment. By adopting these strategies, the aquaculture industry can contribute to a more sustainable and responsible seafood production system.
