Are circular economy principles applied to aquaculture feeds?

Yes. In aquaculture, the circular economy utilises by-products and waste generated by supply chains in the production of food for human consumption. For example, trimmings from fish processing account for about 35% of the fish meal used in aquaculture. Similarly, the by-products from the slaughter of terrestrial animals destined for human consumption can be turned into meal with high nutritional values. Novel ingredients like insect and bacterial meals offer further potential in the utilisation of waste streams as inputs.
