Compound aquaculture feed stands out as the main factor responsible for environmental impacts of fed aquaculture species based on life cycle assessment analyses.  Production and transport of raw materials represent between 30 and 95% of all environmental impact categories, whereas feed processing is the main contributor to greenhouse gas emission (GHG). The objectives of this presentation are to (1) demonstrate past achievements, among which some were made inadvertently, to contribute to the sustainability of aquafeeds, (2) identify challenges yet to be addressed globally and in Israel, and (3) propose a strategic roadmap to improve sustainability of aquaculture feeds that support food production systems for the growing human population.  Israel, particularly in the Negev, can contribute to tackle challenges by considering the limitless possibilities offered by biotechnologies (e.g. microalgae, bacteria and yeast production) in a context of finite resources.  Finally, nutrient recycling and principles of circular economy are pivotal to enhance aquafeed sustainability in such context and will be discussed with consideration for their role in securing food supply in an ever-changing world.
