Although fishmeal is an excellent feed component for trout, there are concerns about its sustainability. Overfishing and the environmental impact of fish meal production have raised questions about its long-term availability. Consequently, there's a growing interest in finding alternative protein sources for fish feed, such as plant-based proteins. The exploration of non-conventional ingredients in trout feed stems from a pressing need to safeguard the environment, promote aquaculture sustainability, and enhance consumer safety. By ensuring the safety of food products, consumer trust in purchasing aquaculture-derived fish is likely to increase, potentially reducing reliance on wild-caught fish. Within this framework, a comprehensive literature review was conducted to identify novel ingredient sources suitable for trout feed. This involved examining the origins of new plant-based ingredients, assessing their physical, chemical, and microbiological characteristics, and evaluating their impact on trout feed production. The findings of this study can inform and enhance feed management strategies in aquaculture, aligning with sustainability objectives and efforts to boost productivity.
