Cover Story: Aquafeed contamination caused by microplastics (MPs) poses a risk to fish health due to their gastrointestinal absorption and translocation to other organs, particularly the liver, triggering oxidative stress. The present study aimed to combine the use of natural astaxanthin contained in natural-based microcapsules to counteract the negative side effects of MPs in juvenile European seabass (Dicentrarchus labrax) fed diets containing MPs. Specifically, starch contained in the microcapsules enabled the coagulation of MPs in fish gut, limiting their absorption and accumulation in all the tissues analyzed. Conversely, natural astaxanthin led to the mitigation of oxidative stress. This technology represents a new and economically affordable approach to promote fish welfare and quality within the aquaculture sector. View this paper
