Do circular economy principles apply to aquaculture feed?
Yes, in aquaculture, the circular economy uses by-products and waste generated by supply chains in the production of food for human consumption. For example, trimmings from fish processing account for approximately 35% of fishmeal used in aquaculture. In addition, by-products of the slaughter of terrestrial animals intended for human consumption can be transformed into meals with high nutritional values. Novel ingredients, such as insect and bacterial meals, offer greater potential in utilizing waste streams as inputs.
