POTENTIAL NOVEL FEED INGREDIENTS IN AQUACULTURE FOR FUTURE FEED: A REVIEW.

There is an increasing awareness of the difficulties associated with ensuring optimal nutrition for everyone, while preserving the environment. This issue is particularly relevant in the context of aquaculture, as it heavily relies on marine resources for essential feed components, while also playing a crucial role in supplying vital nutrients such as omega-3 long chain polyunsaturated fatty acids. Aquaculture is responsible for producing the majority of the world's fish and seafood, making it a significant contributor to global food security. However, the rising costs of traditional feed ingredients and the unsustainable exploitation of natural resources pose significant challenges to aquaculture production. To address these challenges, various methods and techniques are employed, with the recent trend being the utilization of unconventional feed ingredients in the aquaculture sector. These alternative feed sources include plant-based products, various types of algae (both micro and macroalgae), single-cell protein derived from bacteria and yeast, as well as insect meal, poultry by-products, meat and bone meal etc. all aimed at promoting sustainable food production in aquaculture. The objectives of this review are to elucidate the role of "blue-food production" (which encompasses animals, plants and algae harvested from freshwater and marine environments) within a circular bio-economy, to explore how this approach can enhance the sustainability and resilience of aquaculture, and to provide an overview of emerging novel nutrient sources for aquaculture species.
