Bioactive Feed Ingredients used in Aquaculture: A Review

Abstract

Food security is a critical concern for nations like India, where poverty affects access to nutritious food for a significant portion of the population. While India has made strides in addressing this issue through agricultural revolutions, evolving demands necessitate a reformation in aquaculture practices. With a global surge in demand for fish and fisheries products due to their nutritional benefits, aquaculture has become pivotal. However, the intensification of aquaculture brings risks such as disease outbreaks and rising costs of essential feed ingredients like fish meal, particularly impacting the shrimp industry. To mitigate these challenges, exploring alternatives like bioactive feed additives sourced from marine and agricultural origins emerges as a promising solution. Marine derivatives such as algae offer nutritional benefits and bioactive compounds, while agri-industrial wastes provide versatile applications, including medicinal plant extracts and plant-based ingredients. Additionally, complex bioactive feed ingredients like probiotics, prebiotics, metabiotics, and phytobiotics show promise for enhancing the health and productivity of cultivated aquatic organisms. Integration of these alternatives into aquaculture practices presents a sustainable approach to improving food security, feeding efficiency, animal health and economic sustainability in India and beyond.
